Photo Credit: Ewere Diagboya As you move faster and faster with your DevOps practice, there is a piece of the puzzle that seems to be a little snag. That snag can cost you a whole lot, in terms of system security, management and updates. Application Parameters/Configurations; these guys practically determine how our applications run. It spans across database connection, to login credentials for RabbitMQ and other secret credentials. As a security practice, you do not want these credentials to be visible in your codebase when committing your code to your VCS (Version Control System). One of the ways to secure these credentials is by using Environment Variables which can be injected in the particular environment you need those secrets and configurations, instead of the values as they are. There also needs to be a place where these data need to be stored for safe keeping and if possible encrypted where they are stored. We shall be looking at these 3 secret storage solution used by DevOps engineers. Each of these has their pros and cons and we shall be analyzing them with the following criteria: a. Costb. Securityc. API/SDK Integrationd. Features Cost **AWS Secrets Manager**This is a managed service by AWS and according to AWS Pricing, this service costs $0.40 per secret per month $0.05 per 10,000 API calls. For context purposes, if you store 100 secrets (password, API Keys, etc) you pay $40 a month and if you request the value of the secret with a 40,000 API calls in a month you pay $0.2. more here **Hashipcorp’s Vault**This is an open-source tool. Meaning you are in charge of setup and scaling the service. You will need to set it up on a Virtual Machine and the VM you use will determine the cost and other operational costs involved in updating, securing the server in which Vault will be installed and configured on. **AWS Parameter Store**Still a managed service on AWS but this time it is under a feature called Systems Manager. It basically costs nothing. Did you just see that? Yes I mean it costs NOTHING. see here Security **AWS Secrets Manager**Secrets manager is quite a new service which is fully managed by AWS to the security of credentials stored on it is tied to IAM access on your AWS account. You can also integrate Secrets Manager with . Which helps to encrypt the data that is stored. Secrets Manager also comes with a secret rotation feature which allows you to automatically rotate API keys, passwords and more. This can be configured and wired with a Lambda Function to help with the rotation. AWS KMS **Hashipcorp’s Vault**Everything that has to do with the security of the vault application is solely the user’s responsibility. Vault stores the passwords inside the machine it is installed in and encrypts the data. It supports various backend storages; Filesystem, AWS S3, Azure, Google Cloud Storage, MongoDB. secret rotation feature here ( ) more here https://www.vaultproject.io/docs/internals/rotation.html **AWS Parameter Store**Just like the Secrets Manager, the security is tied to your IAM account in AWS. All requests are made either via the API or CLI. The keys for both are generated from the console and used. There is no secret rotation feature of any sort, except you want to customize one. API/SDK Integration Here they all have APIs and SDKs to retrieve stored keys. So for this grading they all pass General Features **AWS Secrets Manager**- Secured storage of secrets on AWS- Allow encryption of keys stored via KMS- Key rotation can be configured within a specific period- Privilege Access Management (IAM) **Hashipcorp’s Vault**- Stores secret in the filesystem or a database- Encryption as a Service- Privilege Access Management **AWS Parameter Store**- Secured storage of secrets on AWS- Allow encryption of keys stored via KMS- Privilege Access Management (IAM) Based on these features. You can choose which you can use for storing and retrieving your secrets. But it is crucial that you have a vault to store password, API Keys and connection strings.

Traditionally speaking, the banking system works with the help of a vast network of reliable intermediaries. Despite its challenges and shortcomings, we continue to rely on it to protect our funds and valuables – primarily in the virtual safe deposit box. This trust has been built over the centuries by the traditional banking system. Meanwhile, in the non-traditional landscape of cryptocurrency, the idea of a self-custody wallet has continued to gain traction even though bad actors are constantly in the news for hacking exchanges. While the crypto industry has undergone significant development, it is still very much plagued by scams and hacks that undermine efforts to build trust among millions of potential users. Crypto has an image problem, despite the promises of a self-custody revolution, and this is only aggravated by the instances of “overnight millionaires”. As a technological innovation, self-custody, which moves the management of assets into the hands of customers, represents a paradigm shift. It eliminates third-party involvement—a feature that can be a lifesaver as many platforms such as Terra, Celsius, and FTX, to mention a few, have crumbled causing significant losses to the tune of $40 billion as per CoinDesk. Building Trust Over Time It has taken several years of legal framing and enhancing the security measures of the conventional banking systems for people to develop trust in those systems. For instance when Silicon Valley Bank went bust, requisite measures to deal with customer losses were instituted without any delay. Crypto business, conversely, is a rather ill-defined and continuously developing market that still has no set rules to follow. Trust in this space has often been lost due to several failures as well as fraud-related cases. Consequently, self-custody appears to be the most viable innovation in such an environment. We can own assets outright and decrease the risk associated with third parties, which makes the process free from their intervention. The Role of Technology in Enhancing Security In the future, as this industry develops, we should also see these self-custody technologies reach the same high levels of trust and reliability as the present-day banking sector. Currently, CCData reveals that over one hundred providers can be identified all over the world to provide custodial solutions to retail and institutional investors looking to invest in crypto assets. The consolidation of the industry is foreseeable, as it is borne out by the experiences of sectors such as banking and the internet when transitions are initiated to tighten up security and instill greater trust in the industry. Distrust of centralized infrastructure is another problem that might appear unfathomable for retail users, but self-custody is imperative. The self-custody market remains to be developing, providing better and more consumer-friendly solutions that handle assets on the user‘s behalf. Additionally, self-custody is not only about transitioning between one technological paradigm and another – but a paradigm shift in thought. That is an indication of a shift towards self-organization and one’s faith in the financial systems. Unfortunately, self-custody will become one of the standards as crypto develops further for those who want their funds to be secure. Challenges Facing Web3 Wallet Management Currently, managing a Web3 wallet comes with the following challenges: Seed Phrases A Web3 wallet most importantly comprises the seed phrase recognized as a recovery phrase. It serves the purpose of becoming a unique identifier, allowing users to restore their wallets on various gadgets. It is a 12-24 random word phrase, and losing such a phrase will result in permanent loss of wallet and any of the funds stored in it. Unfortunately, there is no organized service to recover the phrase, and the total burden lies on the user. The problem lies in the question of how to safely store this seed phrase securely at the same time. It is too long and random that users cannot memorize it easily, and when they write it down or store it in an informatics device, there are some dangers involved. If the physical copy is lost, damaged, or stolen — or if a digital copy of the information is cracked — the user’s wallet could leak or could be locked away forever. Generating and Remembering Strong Passwords The majority of Web3 wallets also force users to set essential passwords to enhance the application’s protection. Such passwords must be used so that one is long and different from those used in the other accounts and contains symbols that cannot be subjected to hacking or brute force. However, this creates a significant challenge: how to achieve the best password creation to meet the standard of secularity while, at the same time be okay with the user to remember it. The reality is that there is no one server that a person can turn to get help, and as such, if the password is gone, so is the wallet. Worse still, fundamental password reset strategies such as receiving password reset links via email are not feasible in Web 3. As a result, the wallet remains closed for all eternity if the user forgets or loses the password to the wallet. This password is only with the user, so password insecurity is still an issue when managing Web3 wallets. Protecting Against Phishing Scams and Malware Crypto phishing scams are one of the most common types of scams actively used in the Web3 ecosystem. The attackers continue hiding behind the replica of any type of service or person, using techniques ranging from private keys to passwords from the user. As pointed out it has been noted that this kind of scam has evolved in a way that when the individual clicks on the links to the sites involved, these look almost like the real site, putting even the intelligent users at the mercy of the con-men. Malware is another huge problem because it is easy to spread an infected file or program into an organization's network. This can be acquired through downloads or by clicking on links in ads and will surreptitiously steal wallet details. For example, some malware may keep track of the clipboard of the user to replace the copied wallet address with a fake one, so as to guarantee that users deposit their cash into the wrong wallet. That is why pointing interest from the user and awareness of threats in the information space is needed to prevent these forms of attacks. Remaining Cautious of Unknown Links and Downloads Among the most used attack methods in Web3 is using links or downloads, which sound familiar or unknown to the user. If the user clicks on a fraudulent link, then the wallet becomes vulnerable to phishing sites, or the user's device is infected with malware. These are attacks with the intent of capturing the private key or otherwise phishing users into signing up for fraudulent transactions. Given the fact that Web3 is a decentralized network system, there is effectively no protection, and users are their self-defense line. This challenge is especially challenging because links can be disguised in several different ways, shapes, and forms. It comes from emails pretending to be from customer support or alert services on social media sites. One can compromise their account easily simply by downloading a well-known wallet plugin from untrusted sources. It makes every exchange that occurs through the platforms a potential risk that needs to be avoided. How GRVT Is Challenging The Notion of Private Key The GRVT Wallet simplifies the user experience through Web Authentication (WebAuthn), which allows users to create and access their wallet using a password and passkeys, avoiding the complexities associated with traditional crypto wallets. The integration of Dfns technology allows users to access their wallets via fingerprint or facial recognition, offering quick and secure authentication similar to traditional online banking. And it blends the user-friendliness of Web2 with the security of self-custody, protecting assets without the technical burdens. By leveraging off-chain, peer-to-peer networks with multi-party computation (MPC) and public key infrastructure, it is able to guarantee: No Single Point of Failure: GRVT Wallet supports multiple devices, creating multiple security layers to prevent breaches. Responsive Recovery: Recovery wallets and backup codes provide fail-safes if credentials are lost. Uninterrupted Transactions: Linking new devices doesn’t affect public key, allowing continuous transfers. Conclusion The question of why the conventional banking system continues to thrive despite its shortcomings and the revolutionary advantage of the self-custody system boils down to trust. Millions around the world still feel safe to keep their money and other valuables in the banks and the incidence of crypto scams and losses has increasingly overshadowed the prospects of a generational transition from modern banking to cryptocurrency and self-custody wallet. This problem is further aggravated by the technical complexities surrounding the use of a smart contract wallet, which requires a level of skill to operate. Nonetheless, the possibility for both systems to exist side-by-side in the future is worth considering.

A big event is now taking place in the heart of Singapore, a nation that is well-known for its innovative and financial practices, and it is likely to have a huge influence on the field of decentralised finance (DeFi). For Thetanuts Finance, this endeavour, which focuses on reinvesting and producing Liquid Restaking Tokens (LRTs), represents a big step forward in comparison to previous endeavours. This also represents the beginning of a new century for users of Pendle's PT-eETH, which will give them with opportunities that have never been made available to them before to maximise their profits in areas that have not been explored before. Now, let's have a look at this incredible innovation and how it will fundamentally revolutionise the way that investors in decentralised finance make choices. A Leap into the Future of Staking Imagine if the Ethereum (ETH) that you have staked is actively protecting other networks and providing you with rewards that go above and beyond the Ethereum Mainnet. The minds behind restaking, EigenLayer, made it happen, so it's not just a dream. Through the usage of $stETH in liquid restaking protocols, restaking enables users to create "Liquid Restaking Tokens" (LRTs), a novel kind of asset that is expected to transform return generation. Leading this change is EtherFi, whose Total Value Locked (TVL) is more over $2.5 billion. Users may now mint LRTs—specifically, $eETH—thanks to EtherFi. By doing so, they can have access to additional perks like EigenLayer points and protocol loyalty points. However, since they increase the potential rewards to a whole new level, third-party LRTs like Pendle Finance's PT-eETH are what truly pique people's attention. The Innovation of PT-eETH With a fixed annual percentage rate (APY) of around 20% and the guarantee of payback for $eETH at a 1:1 ratio at the conclusion of the period, Pendle Finance's PT-eETH stands out as a real novelty. Pendle Finance distinguishes itself in the competitive DeFi industry by providing investors with a unique opportunity to get consistent rates and transparent profits. Thetanuts Finance: Pioneering New Frontiers As far as on-chain options protocols go, Thetanuts Finance is in the forefront. It is currently entering the LRT industry with its Leveraged LRT Strategy Vault. This vault is not simply another DeFi product; rather, it is a strategically important tool intended to maximise the potential of $PT-eETH and provide customers with previously unheard-of returns growth. Imagine 'zapping' your $PT-eETH into a yield generation maelstrom, where it remains in one place and works to generate more profits. The Leveraged LRT Strategy Vaults from Thetanuts Finance make this feasible. Users may use $PT-eETH to borrow $ETH. Once borrowed, $ETH is placed in the ETH Call ("ETH-C") Basic Vault, where users may profit from option bonuses and features, but there is a catch: they must accept short volatility risk.    The yield creation symphony that Thetanuts Finance creates is composed of EigenLayer Points, EtherFi Loyalty Points, Pendle $PT-eETH Fixed Yield, Thetanuts Finance $ETH-C Basic Vault Option Premiums, and the soon-to-be-released $NUTS Rewards. This creative approach to yielding profits demonstrates Thetanuts Finance's commitment to provide its consumers value and advantages. The Ripple Effect: Shaping the DeFi Ecosystem Not only is Thetanuts Finance's Leveraged LRT Strategy Vault a brand-new product, but it is also a disruptive force that is anticipated to generate a substantial amount of demand within the DeFi community. Due to the fact that there are already 150,000 $PT-eETH in circulation, the market may undergo substantial changes, which highlights the significance of the novel initiative that Thetanuts Finance is working on. In light of the fact that Thetanuts Finance is getting ready to launch extra procedures for making use of Liquid Restaking Tokens (LRTs), additional choices are becoming accessible. Only the beginning has begun with this strategic vault. It is a stepping stone to a future in which LRTs will play a significant role in the investment plans of decentralised finance and intelligent investors will be able to get a greater variety of returns. The Essence of Innovation When it comes to the decentralised financial business, Thetanuts financial is a perfect example of what it means to innovate on a basic basis. It is clear that the company is continually looking for new ways to make money, not just for its clients but for the whole DeFi community as a whole, as seen by the fact that it has joined the market for Leveraged LRT Strategy Vaults. The company known as Thetanuts Finance is among the most successful businesses operating in an industry that thrives on change. They are in the vanguard of paving the way for a future in which decentralised finance expands beyond the traditional boundaries of the sector and embraces fresh investment and wealth generation tactics. This future is being paved by them. At the same time as we are entering a new era of decentralised finance (DeFi), we are able to feel the excitement that is rising up on our shoulders. The debut of Thetanuts Finance's Leveraged LRT Strategy Vaults is not only a significant achievement, but it is also a symbol of hope and a testament to the boundless possibilities that decentralised finance (DeFi) has to offer. This launch is a significant milestone. It is possible that pioneers like Thetanuts Finance, who are not afraid to go into unexplored territory, are responsible for the hopeful view that can be found about the future.

Subscribe to my Data Youtube Channel and Podcasts, Links Here Data Vault modeling is an approach to data warehouse design that offers a unique method for handling complex data from disparate sources in a way that is agile, flexible, and scalable. Developed by Dan Linstedt in the early 2000s, Data Vault modeling addresses many of the challenges associated with traditional data warehousing methods, such as the star schema and snowflake schema. By emphasizing the separation of concerns between the structure of data and the integration of data, Data Vault enables businesses to adapt quickly to changes in their data environment, making it an ideal choice for dynamic, fast-paced industries. The core philosophy of Data Vault modeling revolves around capturing data in its most granular form, ensuring that every piece of information is stored without loss of detail or context. This approach not only facilitates better data governance and compliance but also enhances data quality and usability across the organization. Core Concepts of Data Vault Modeling At the heart of Data Vault modeling are three primary concepts: Hubs, Links, and Satellites. Each plays a vital role in the structure and function of a Data Vault model. represent the unique business keys within the organization. They are the cornerstone of the Data Vault architecture, ensuring that data is accurately linked across various sources. Hubs connect Hubs together, forming relationships between different pieces of data. These Links are crucial for establishing the context and associations among disparate data elements, making it possible to construct a comprehensive view of the organization's data landscape. Links provide descriptive details about the Hubs and Links, such as attributes, historical changes, and timestamps. Satellites allow for the storage of context and change over time, enabling detailed analysis and reporting. Satellites Data Vault modeling stands out by offering a way to accommodate big data and analytics needs, thanks to its inherent scalability and flexibility. Unlike traditional models that may require significant redesign as new data sources are introduced, Data Vault's modular nature allows for easy expansion and adaptation without disrupting existing structures. Comparing Data Vault with other data modeling techniques highlights its advantages in handling complex and changing data environments. While star schemas and snowflake schemas offer simplicity and are well-suited for specific reporting needs, they lack the agility and scalability that Data Vault brings to handling diverse and evolving data sources. Benefits of Data Vault Modeling Implementing Data Vault modeling in data warehousing projects brings several key benefits: Scalability and Flexibility Due to its modular design, Data Vault can easily scale to accommodate growing data volumes and complexity. New Hubs, Links, and Satellites can be added to the model without disrupting existing structures, making it highly adaptable to changes in business requirements.

Best Practices for Data Vault Modeling Adhering to best practices in Data Vault modeling can significantly enhance the success of your data warehousing project. Here are some key tips to follow: Effective Hub, Link, and Satellite Design : Focus on business keys that are stable and uniquely identify business objects. Hubs : Model relationships clearly, including many-to-many relationships, to accurately represent business processes. Links : Capture as much descriptive information as necessary, considering the rate of change and the importance of historical data. Satellites Data Loading Strategies : Depending on your data volume and frequency of updates, choose between full loads (reloading all data) and incremental loads (loading only new or changed data) to optimize performance. Full Loads vs. Incremental Loads Managing Historical Data and Changes Over Time Implementing a robust strategy for tracking historical changes is crucial. Use Satellites to record time-variant attributes and employ effective dating techniques to keep track of historical data. Following these best practices and considerations will help ensure a smooth implementation of Data Vault modeling in your organization, leading to a flexible, scalable, and future-proof data warehouse. Example of Data Vault Modeling To better understand how Data Vault modeling works in practice, let's walk through a simplified example involving customer orders. This example will help illustrate the structure and relationships between Hubs, Links, and Satellites in a Data Vault model. Scenario Overview Consider a retail company that processes customer orders. We want to model data involving customers, products, and orders. The Data Vault model will include three Hubs (Customer, Product, Order), one Link (Order Details), and Satellites to store descriptive and historical information. Hubs Hubs represent the core business concepts. In this scenario, we have: Hub Customer (Hub_Customer) Column Name Description HUB_ID Unique identifier CUSTOMER_ID Business key (ID) LOAD_DATE Date of record entry RECORD_SOURCE Source of data Hub Product (Hub_Product) Column Name Description HUB_ID Unique identifier PRODUCT_ID Business key (ID) LOAD_DATE Date of record entry RECORD_SOURCE Source of data Hub Order (Hub_Order) Column Name Description HUB_ID Unique identifier ORDER_ID Business key (ID) LOAD_DATE Date of record entry RECORD_SOURCE Source of data Link Links model the relationships between Hubs. In this case, we have: Link Order Details (Link_OrderDetails) Column Name Description LINK_ID Unique identifier ORDER_HUB_ID Foreign key to Hub_Order PRODUCT_HUB_ID Foreign key to Hub_Product CUSTOMER_HUB_ID Foreign key to Hub_Customer LOAD_DATE Date of record entry RECORD_SOURCE Source of data Satellites Satellites provide descriptive details and historical information about Hubs and Links. Satellite for Customer (Sat_CustomerDetails) Column Name Description HUB_ID Foreign key to Hub_Customer NAME Customer's name EMAIL Customer's email LOAD_DATE Date of record entry RECORD_SOURCE Source of data Satellite for Product (Sat_ProductDetails) Column Name Description HUB_ID Foreign key to Hub_Product NAME Product name DESCRIPTION Product description PRICE Product price LOAD_DATE Date of record entry RECORD_SOURCE Source of data Satellite for Order Details (Sat_OrderInfo) Column Name Description LINK_ID Foreign key to Link_OrderDetails QUANTITY Quantity ordered ORDER_DATE Date of the order DELIVERY_DATE Expected delivery date LOAD_DATE Date of record entry RECORD_SOURCE Source of data Continuing from our example of Data Vault modeling with customer orders, let's delve into how these models are used in practice and the benefits they offer. Using the Data Vault Model in Practice Querying Customer Orders Suppose you want to generate a report showing all orders placed by a specific customer along with product details. Using the Data Vault model, you would: : Use to find the corresponding to the customer of interest. Identify the Customer Hub_Customer HUB_ID : With the customer's , query to retrieve all s associated with the customer. Find Related Orders HUB_ID Link_OrderDetails ORDER_HUB_ID : For each , look up to gather details about each order, such as quantity and order date. Fetch Order Details ORDER_HUB_ID Sat_OrderInfo : Use from to join with for product names, descriptions, and prices. Retrieve Product Information PRODUCT_HUB_ID Link_OrderDetails Sat_ProductDetails Analyzing Product Sales Over Time To analyze how product sales have varied over time, you can: : Query and to collect quantities and order dates for all products. Aggregate Order Data Link_OrderDetails Sat_OrderInfo : Use to join with for product names. Join with Product Information PRODUCT_HUB_ID Sat_ProductDetails : Group the aggregated data by product name and time period (e.g., month, year) to analyze trends and patterns in product sales. Time-based Analysis Benefits of Using Data Vault Models in Practice Flexibility in Querying Data Vault's separation of business keys (Hubs), relationships (Links), and descriptive information (Satellites) offers unparalleled flexibility in querying data. Users can easily navigate between different aspects of the data, combining them in various ways to answer complex business questions. Scalability As new data sources are integrated, new Hubs, Links, or Satellites can be added without disrupting existing structures. This modular growth capability ensures that the data warehouse can scale alongside the business. Auditability and Data Governance Each component in a Data Vault model includes and , providing a clear audit trail of when data was added and its source. This feature supports rigorous data governance practices and compliance requirements. LOAD_DATE RECORD_SOURCE Handling Historical Data The Data Vault model excels at managing historical data through Satellites. Changes over time are captured in detail, allowing businesses to track trends, perform historical analyses, and make informed predictions. Enhanced Data Quality By clearly separating different aspects of data and maintaining detailed metadata, Data Vault models help in identifying and rectifying data quality issues. This structure promotes high data integrity and reliability for reporting and analytics. Conclusion The practical use of Data Vault models, as illustrated through querying customer orders and analyzing product sales, demonstrates the methodology's strengths in flexibility, scalability, and data governance. By adopting Data Vault modeling, businesses can build a robust foundation for their data warehousing and analytics needs, capable of adapting to change and supporting complex data landscapes.

Intro to Data Vault Modeling: Agility, Scalability, and Practical Applications Explained

After three years as co-founder and CTO at Yield Protocol, I decided to become an to other projects. Euler Finance is one of my first clients, and has taught me a great deal about what I can do for others. It has revealed a niche that no other person is working on, that few can do as well as I can, and that some clients will appreciate and pay for. advisor and consultant This article is many things: a barely disguised marketing product to land more clients, a technical review on the EVC, but mostly a heart-felt effort to explain what it is that I have found that I can do, that I love doing, that is useful, and that is a viable career. It is extraordinary. An Architecture and Implementation Review My work reviewing the EVC was not a security audit, even if it makes the EVC more secure. I guess you could call it an architecture and implementation review. My goal was to simplify the EVC, to decrease the degree of surprise from those studying the codebase, to increase the quality of the docs, to reduce attack surfaces. In doing so, aesthetics played an equal role to technical expertise. It is a bit of an art. That review played on my natural talents, and the team at seem to be happy. I feel I brought significant value for them, at a fraction of the cost of an audit. Euler Now that the EVC is public, I can describe the work on detail. I’ll do the same for the upcoming Euler products, as well as a couple other clients in my pipeline that can’t be disclosed yet. Maybe one day it will become an industry standard. The was 1049 sloc of new code distributed over 5 contracts, already after several audits, plus 231 sloc of a library from Euler v1 that had been audited several times and seen significant production use. original code The review of the EVC happened over 19 hours of work spread over 3 weeks. The was 972 sloc, with the library unchanged. 6 external functions were removed, as well as a number of internal functions. Significant clarity was achieved over the critical features in the implementation, as well as with the documentation. resulting code Where others take pride in codebases with 100k sloc of solidity, I take pride in removing 75 lines and 6 external functions from a single contract. The following sections describe the different features of the EVC, and how they were reviewed and refactored. The EVC as a Flexible Router The EVC implements a maximally flexible routing system that allows several modes of user interaction, along with call nesting through reentrancy and checks deferred. As a complex and mission-critical feature it was simplified to facilitate audits and reduce attack surfaces. From the original implementation, we did the following changes. The external function was removed. recoverRemainingETH The external function functionality was merged into call. callback The internal function was merged into impersonate. impersonateInternal The restriction on calling the ERC1820Registry was removed. The restriction on using for callbacks was removed. batch The and functions were renamed to explicit descriptors. impersonate callInternal The authentication subsystem was refactored and renamed for clarity. The resulting implementation is more compact, has less requirements, is better named, and in general is simpler. Call Depth Tracking The original implementation included an advanced mechanism to keep track of the exact level of nesting at each call, which would be used to detect when the execution is at the outermost level of execution and the deferred checks should be executed. Upon careful analysis, it was possible to remove this mechanism in favour of a simple and explicit boolean variable set in the context in the outermost nesting level. Operator Authentication It was possible to simplify the operator authentication feature, replacing authenticateOwner and authenticateOwnerOrOperator for a single authenticateCaller function. Apart from making the code easier to understand, this also removed duplicated code which is a risk in itself. Check Validation The EVC implements an advanced system of flexible checks. Checks on accounts and vaults can be mandated by the caller, the controller, or EVC functions that keeps track of user and vault associations. This system was mapped out with the areas of risk pinpointed. The collusion of controller and operator roles in a single account could be exploited with damages to the users that allowed the collusion to happen. The capacity of the controller to forgive checks in the context of liquidations is an area of risk which cannot be eliminated. The capacity of callers to clear deferred checks by executing them immediately was an area of concern, as it could be unexpected by those that required the checks. This could be addressed by removing the capacity. Conclusion A couple of months ago, when I started an advisory and consultancy career path, I had no idea about what was that I was actually doing, and in particular I didn’t know what my actual work would be. Thanks to Euler Finance, I’ve had a glimpse of a service that I love doing, that others find useful, that I’m good at, and that others will pay for. That is much more than I could have expected. With regards to the EVC, none of the ground-breaking features in the EVC are my ideas, I take no credit for that. However, I’m immensely proud to have steered its implementation towards a state that I find more beautiful, safer, easier to integrate with, and easier to audit. I am incredibly grateful to the team at Euler, but in particular to two people. for trusting me and hiring me even when I had such an unclear work plan, and also to , lead developer for the EVC, for his patience in replying to my questions and his open-mindedness to have his code criticised, sometimes refactoring it himself beyond my expectations.

Binance Accused of Unregistered Sales of Simple Earn and BNB Vault Products

SEC v. Binance Court Filing, retrieved on June 5, 2023 is part of . You can jump to any part in this filing . This is part 41 of 69. HackerNoon’s Legal PDF Series here FACTS VII. BINANCE AND BAM TRADING ENGAGED IN UNREGISTERED OFFERS AND SALES OF SECURITIES. C. Binance Offered and Sold Its BNB Vault and Simple Earn Programs as Securities. 325. Binance has offered two other securities on the Binance.com Platform—the “BNB Vault” and “Simple Earn” programs. 326. Binance has regularly marketed the Simple Earn and BNB Vault programs as profit-making opportunities to investors in the United States and elsewhere. 327. Binance markets Simple Earn as programs that pay interest to investors who lend their crypto assets to Binance for fixed or flexible lengths of time. The interest paid depends on the crypto asset lent and the duration of the loan. For instance, investors who lent a particular crypto asset through Simple Earn as of April 24, 2023 were promised profits of 18.9%. 328. Binance determines the Simple Earn rate for each of its offerings at its discretion, taking into account various “factors which are carefully designed to ensure that rewards paid to users are sustainable and competitive.” 329. According to Binance, it may pool assets loaned through Simple Earn and use its managerial expertise to deploy them “for a variety of purposes,” including on-chain staking, loans, or for operational purposes by other business units within Binance. 330. Throughout the spring of 2020, Binance tweeted that it was offering a 15% APR for participants in the BUSD-specific Simple Earn product, and 10% in the Simple Earn product for another crypto asset. 331. BNB Vault is a similar program that is limited to holders of BNB and described on Binance.com as a “BNB yield aggregator” whereby investors can lend their BNB to Binance to earn investment returns. 332. In November 2020, Binance announced the BNB Vault launch: “#Binance Launches BNB Vault – Earn Daily Income from the $BNB Ecosystem.” 333. Binance states on its website that BNB “deposited” in BNB Vault will be “flexibly allocated in different products to help users maximize potential rewards.” These products include Simple Earn and “Launchpool,” a product advertised as rewarding users for staking tokens in connection with new token launches. Similar to Simple Earn, Binance has offered varying APR returns for BNB Vault investors. 334. One tweet from Binance touted the profit potential of BNB Vault: “Just one click can increase how much you earn with your #BNB. BNB Vault combines the multiple income benefits of #Binance Smart Chain, Launchpool, Savings, #DeFi Staking, and more through just one interface.” A second tweet linked to a Binance.com page with a heading “Introducing BNB Vault: One-Click Earning for Your BNB Holdings.” 335. In both the Simple Earn and BNB Vault programs, Binance pools the crypto assets lent by investors and uses those assets to generate revenue that was used to pay returns to investors in Simple Earn and BNB Vault. Investors share pro rata the benefits of their pooled investments in the Simple Earn and BNB Vault programs. 336. Binance exercises discretion and uses its entrepreneurial expertise in managing both programs, including identifying liquidity needs, negotiating with Launchpool issuers, choosing terms, holding and controlling the invested assets, and generating revenue, through its operation of the Binance.com Platform to pay the Simple Earn and BNB Vault investors. 337. From October 2019 through October 2022, at least 3,200 and as many as 16,500 U.S. investors have participated in the Simple Earn investment programs, and at least 1,400 U.S. investors have participated in the BNB Vault program. 338. Since the inception of each, Binance has thus offered and sold both Simple Earn and BNB Vault as investment contracts and, therefore, as securities. Continue Reading .

How Binance Offered and Sold Its BNB Vault and Simple Earn Programs as Securities

In its ongoing journey to reshape the crypto investing landscape, Struct Finance, a DeFi platform that enables investors to engage with tailored interest rate products linked to digital assets, is thrilled to announce the launch of the BTC.B-USDC Vaults. The tranche-based BTC.B-USDC Interest Rate Product was made possible by effectively leveraging Avalanche’s BTC.B (Bridged Bitcoin) for DeFi applications. The new vault beautifully complements Struct Finance’s Genesis USDC Vaults, heralding an exciting era in DeFi yield opportunities. Struct Finance built the new vault on top of GMX's Liquidity Provider Token (GLP) to generate predictable yields for BTC in the form of fixed returns, and USDC in the form of variable returns, while still leveraging a secure asset and minimizing volatility and exposure to other risks. “Our BTC.B-USDC Vaults represent an innovative application of Bitcoin in DeFi. We're taking full advantage of Avalanche's Bridged Bitcoin (BTC.B) to bring about a fresh wave of opportunities in the digital asset space,” said Ersin Dalkali, the Co-founder of Struct Finance. While continues to dominate the market, its inherent lack of a DeFi layer has traditionally made native yield generation quite challenging. Avalanche has unlocked new possibilities for Bitcoin in DeFi with BTC.B (Bridged Bitcoin). Unlike WBTC which relied on centralized bridges, BTC.B is minted via Avalanche Core — a decentralized bridge — and can be trustlessly bridged across networks using the Layer Zero bridge. Bitcoin At present, Bitcoin investments in prominent lending pools yield between 0.2–0.5%. Even the stable swap pools offering wBTC-BTC.B products only manage to deliver returns of about 2%. Struct’s BTC.B-USDC product shatters these limitations, offering significantly higher yields. The purpose of BTC.B is to empower BTC holders to explore DeFi opportunities on the Avalanche blockchain, without the need to acquire secondary tokens or rely on centralized bridges. BTC.B represents BTC coins transferred to the Avalanche blockchain in the form of ERC-20 tokens. With over 6000 BTC bridged and a fully diluted value of $180 million, BTC.B is carving a niche for itself in the crypto arena. The Bitcoin ETF applications by BlackRock, WisdomTree, and Invesco – three of the world’s leading asset managers – are not just a mere submission. It is a signal that the traditional financial realm is ready to embrace Bitcoin on a new level. Recently, the US Securities and Exchange Commission (SEC) gave the green light to a 2X leveraged Bitcoin ETF, sparking an enthusiastic wave of speculation and anticipation for approval of a spot Bitcoin ETF. Disclaimer: This release is for informational purposes only and should not be construed as financial promotion. Delta hedging Amid the highly volatile crypto industry, Struct Finance’s Interest Rate Products allow anyone to split and repackage the risk of any yield-bearing DeFi assets in different parts to fit their risk profile through an innovative process called “tranching.” Every Interest Rate Product is a single vault split into two portions, or tranches that have different return configurations: A Fixed-return Tranche for conservative investors looking for consistent returns A Variable-return Tranche for investors with a higher risk appetite seeking superior returns The yield from the underlying asset flows into the fixed tranche first to ensure predictable returns. The remainder is then allocated to the variable tranche, which gets enhanced exposure to the underlying yield-bearing asset. Compared to the fixed tranche, the variable tranche might accrue more yield, less yield, or no yield. As part of its BTC.B-USDC Vaults, Struct Finance has implemented a unique approach to managing investment risk: delta hedging. While the fixed tranche takes center stage with its high yield, the variable side of the product offers an additional layer of intriguing complexity and potential. Upon deployment of funds into the vault, the BTC.B in the fixed tranche gets converted into GMX’s GLP token, setting up a position that’s short Bitcoin against GLP and contributing a negative delta. In contrast, the USDC on the variable side is converted into GLP, which inherently carries a positive delta. This innovative delta-hedged product design achieves a fine balance between the positive and negative delta forces. It results in a robust strategy that allows investors to confidently navigate the crypto market’s inherent volatility. This artful interplay of the fixed and variable sides within the vaults opens the doors for investors to tap into the potential of Bitcoin investments like never before. By catering to a diverse range of risk appetites, Struct Finance ensures that both retail and institutional investors can tailor their strategies to maximize their returns, regardless of market conditions. About Struct Finance Struct Finance is at the forefront of the DeFi revolution, with a vision to transform the design and utility of financial products. It empowers users to design their own financial instruments, harnessing the power of tokenized, yield-bearing positions to unlock a world of diverse investment opportunities. Moreover, its cutting-edge financial products adopt a tranche-based system, smartly distributing yield between different investor classes. This balanced approach guarantees a steady yield for risk-averse investors while also offering the prospect of heightened returns to the more adventurous. Initially available on Avalanche, Struct Finance plans to go multichain in the near future.

A few months ago, I made a video on and the several security shortcomings of . One of them being the closed, proprietary security model, especially given how sensitive passwords are to our online ecosystem. LastPass getting hacked LastPass With a proprietary, closed-source security model and the hosting of passwords in the cloud, many users have chosen to move to open-source, self-hosted solutions, where they can have full visibility into the source code and full control of how their passwords are handled. There are pros and cons to this solution. Pros Secure and private data storage. Uncompromised data security as long as the system has been properly secured. Full user control over where passwords are stored. It's a bit harder than opening notepad and pasting in passwords, but it provides easier integration and flexibility once you have the vault setup. Cons Lack of flexibility with a hybrid device ecosystem like computers and phones. Active maintenance and security of the server. So when should you choose to self-host over using a cloud option? If you are a one-person team, managing your own passwords is doable and can also be fun for users who want to partake in this project. It can also be risky to self-host a [password vault](https://password vault) if a user lacks full security competence and exposes the vault to the internet. The more users one has to manage, the harder it gets, in terms of compute power to serve the various devices as well as managing many users. So if you are in a family or business, using a cloud option may be easier. Let’s set up a self-hosted vault in Passbolt using a docker container. I am on a Windows 10 machine.

The Treasure Vaults of Opar

With the rising adoption of healthcare apps and wearable devices that gather medical data, the importance of data privacy for healthtech companies is greater than ever. Broadly defined, “ . While this includes applications from traditional healthcare providers, it also includes technology that handles healthcare data, like fitness apps, nutrition apps, or biometric wearables. This means that the companies behind these technologies — healthtech companies — often deal with . healthtech” is any technology that assists with someone’s healthcare protected health information (PHI) Healthtech companies greatly benefit consumers, but working in this space also means plenty of risks. For example, is a set of rules that governs how organizations use and protect the PHI of their patients and customers. HIPAA Companies that work with PHI must ensure they’re HIPAA-compliant, lest they face fines, lawsuits, or closures. However, HIPAA is only a starting point if you want to provide truly robust privacy protections for your customers. In this article, we’ll look at how your healthtech company can implement greater privacy safeguards by using a in your applications. We’ll also discuss why it’s important to exceed the bare minimum of what is required by law for PHI, as doing more for data privacy can actually win you customers and improve your healthtech products. data privacy vault But first, let’s lay the groundwork with a brief treatment of HIPAA and PHI. Understanding HIPAA Compliance and PHI HIPAA is the baseline of compliance for protecting patient health data. Commonly considered the legislation which codified medical data privacy in the United States, HIPAA represents the minimum bar for safeguarding PHI that any healthtech company must meet. Why PHI is Unique Financial data, such as a reissued credit card or an updated credit score can change, and we have standards, such as , to regulate the use of this data. Personally identifiable information (PII), such as a home address or a driver’s license number can also change. For handling PII, we have regulations like or . PCI GDPR CCPA However, PHI is a unique kind of data because the majority of PHI typically doesn’t change. For example, laboratory results or entries in a patient’s medical history are fixed. Because of this, HIPAA takes the protection of client health data very seriously. How PHI is defined One of the key ways that HIPAA protects patients in the US is by defining what sort of data is considered PHI. Essentially, PHI is any information that can be used to identify an individual and that is related to the following: That individual’s past, present, or future physical or mental health or condition The provision of healthcare to that individual Payment for the provision of healthcare to that individual That means that if someone’s name, contact information, photo, or ID number is attached to the health-related data point, it’s also considered PHI, and it needs to be kept safe. HIPAA rules apply to what the US Department of Health and Human Services (HHS) calls “ ” as well as . If you’re operating without HIPAA compliance, then you’re liable to face some serious penalties, including hefty fines, customer remediation costs, and even being added to a public list of breaches commonly referred to as the HIPAA . Covered Entities and Business Associates any health-related applications that deal with PHI So, if your business takes health data and ties it to any kind of identifier for a specific person, then it is very likely to be subject to HIPAA. Wall of Shame From the vantage point of simple compliance, it’s hard to overstate the importance of HIPAA for healthtech companies. How a Data Privacy Vault Protects PHI Fortunately, protecting your customers’ PHI data is possible. The HHS provides . Companies can detach health data from identifiers so that it can no longer be used to identify an individual. guidance on how to de-identify PHI However, the challenge for healthtech companies is ensuring that they’re doing this correctly. There’s no room for mistakes. If you try to “roll your own” solution, you take precious engineering resources from your core business needs, and you’ll lack the confidence that you’ve covered all your bases. Instead, many of today’s healthtech companies are looking to the architectural pattern. A data privacy vault — and specifically one that is designed to deal with healthcare data — allows you to securely store identifiers for customers in an isolated, encrypted data vault that’s from normal transactional data. This kind of enables you to de-identify health data, protecting both your customers and your business. By providing tokenization, masking, and redaction capabilities, a data privacy vault makes working with protected data much less risky. data privacy vault separate healthcare data privacy vault Now that we’ve discussed the risks of non-compliance and the solution for protecting customer PHI, the big question is this: Is it worth it? Instead of adopting tried-and-tested tools to secure your customer data fully, would it be acceptable just to assume some risk and hope for the best? Let’s consider this. Reducing the Risk (and Scope) of a Data Breach Perhaps your company is already up and running a data privacy vault, and you’ve implemented other mechanisms for protecting your customers’ PHI. without You may feel like you’ve already invested a lot and don’t want to sink more effort into something that feels like a net-neutral investment. But it’s important to realize that you can still end up on the HIPAA Wall of Shame with a breach that impacts even if you have basic protections in place. as few as 500 customers, Not only that, but the best repayment to your customers for their trust in you is building a more trustworthy system. While it may seem you’ve met HIPAA’s standards for de-identification of PHI, reducing even a small risk of a breach by introducing a data privacy vault can win even greater trust from your customers. Take a look at the above example architecture. Notice that only tokenized, masked, or redacted information would be passed between different parts of your systems, allowing you to exceed HIPAA requirements and keep you off the Wall of Shame. Building Customer Trust Building a privacy-centric system will do more than just keep you out of trouble. It can also be a great tool for driving customers to your business. By protecting customer data, you can actually make better use of it. Isolating customer PHI in a data privacy vault allows you to use that data in various workflows and extract valuable insights identifiable data. without compromising Choosing a good tool for managing PHI will also require you to establish various data governance policies and access controls. By specifying these operational pieces of your business, you can ensure your customers’ trust is well placed. Given the high demand for privacy in any consumer technology today— and especially in healthtech — prioritizing these policies and standards sets your company apart as a leader in privacy, differentiating your business from competitors. Conclusion If you still want to learn more about HIPAA compliance or how a data privacy vault can help you with other aspects of HIPAA, there’s out there for that. plenty of information Fortunately, with the great tools available on the market, building a secure solution for your healthtech business is completely possible and easy to start immediately. Protecting your customers from compromised PHI is serious business, so make sure to use the right tools to safeguard your customer health data. Also published here.

How a Data Privacy Vault Protects PHI for Healthtech Users

Keeping track of all our passwords is a hard thing, especially because it’s a bad practice to re-utilize them across multiple accounts, they also must be strong and hard to guess. Our best solution is to use a password manager, this way we can get strong and hard-to-guess passwords and we avoid the hassle of memorizing all of them (which btw I can’t), they are all in one place, but what happens if your password manager has a security breach and your passwords vault gets leaked? That happened four months ago, and they are only telling you now. A Quick Recap of What Was Happening August 25, 2022 LastPass posted an that they had noticed an unusual activity two weeks earlier and started investigating it, but there was no evidence of access to any customer data. Apparently, the attacker only had access to a portion of the source code through the development environment. official note September 15, 2022 They had completed their investigation and forensics with the team, after finishing the investigation they concluded that the attackers activity was limited to a 4-day time frame in August and that the team was quick to contain the incident. Mandiant Also according to their investigation, the breach happened in the development environment, which technically has no access to customers data or password vaults. Even having access to users encrypted passwords vaults, nothing can be done without the user’s master password, which is part of their zero-knowledge security model (keep that last sentence in mind though) November 30, 2022 As part of their transparency commitment, they added an update to the breach situation, stating that they noticed unusual activity on a third-party cloud storage service, which is both shared by LastPass and GoTo, and again, they launched an investigation with the Mandiant team. This time they stated that the breach that happened in August actually gave the attacker access to “certain elements” of customers information, but that all the passwords are safe, again, due to their zero-knowledge security model. What is Happening Now? The day is December 22, 2022, LastPass came to the public to tell that, on the security breach of August, the attacker was able to get personally identifiable information, including company name, end-user name, emails, billing addresses, telephone numbers and IP addresses, as well as, wait for it, . 🤯 Password Vaults According to LastPass, your password vault is totally safe and is uncrackable, considering you have followed all their guidelines to secure master-password creation. At the moment there is no evidence that any unencrypted credit card data had been leaked, which at this point, I have my concerns since they took 4 months to come to the public saying that PII and password vaults are in the attackers hands. You can check the entire Notice of Incident here How Safe Are my Passwords? If you have followed the entire LastPass guideline for password creation, you are probably safe, attackers will start using dictionaries of billions of already leaked passwords (RockYou2021 dictionary has incredible 8.4 billion passwords) to speed up the process. Attackers may also try to brute-force your password, but if you think it would take them a really long time, think again. As technology evolves, it also decreases the time to crack passwords, the jump between an RTX 3090 and an RTX 4090 is almost 2x for nearly every algorithm. You might be wondering how much time then, would it take for someone to crack a complex password, someone actually tested that with the most recent hardware, they used an RTX 4090 8-card rig and were able to crack a highly complex 8 digits password in 48 minutes using Hashcat, according to this article. BitDefender So to be extra sure that your accounts are safe is highly recommended that you change all the accounts passwords that you have stored within LastPass, including your master password.

The Count of Monte Cristo,by Alexandre Dumas, père is part of HackerNoon’s Book Blog Post series. You can jump to any chapter in this book here: . Volume Four, Chapter 74: The Villefort Family Vault [LINK TO TABLE OF LINK] Chapter 74. The Villefort Family Vault Two days after, a considerable crowd was assembled, towards ten o’clock in the morning, around the door of M. de Villefort’s house, and a long file of mourning-coaches and private carriages extended along the Faubourg Saint-Honoré and the Rue de la Pépinière. Among them was one of a very singular form, which appeared to have come from a distance. It was a kind of covered wagon, painted black, and was one of the first to arrive. Inquiry was made, and it was ascertained that, by a strange coincidence, this carriage contained the corpse of the Marquis de Saint-Méran, and that those who had come thinking to attend one funeral would follow two. Their number was great. The Marquis de Saint-Méran, one of the most zealous and faithful dignitaries of Louis XVIII. and King Charles X., had preserved a great number of friends, and these, added to the personages whom the usages of society gave Villefort a claim on, formed a considerable body. Due information was given to the authorities, and permission obtained that the two funerals should take place at the same time. A second hearse, decked with the same funereal pomp, was brought to M. de Villefort’s door, and the coffin removed into it from the post-wagon. The two bodies were to be interred in the cemetery of Père-Lachaise, where M. de Villefort had long since had a tomb prepared for the reception of his family. The remains of poor Renée were already deposited there, and now, after ten years of separation, her father and mother were to be reunited with her. The Parisians, always curious, always affected by funereal display, looked on with religious silence while the splendid procession accompanied to their last abode two of the number of the old aristocracy—the greatest protectors of commerce and sincere devotees to their principles. In one of the mourning-coaches Beauchamp, Debray, and Château-Renaud were talking of the very sudden death of the marchioness. “I saw Madame de Saint-Méran only last year at Marseilles, when I was coming back from Algiers,” said Château-Renaud; “she looked like a woman destined to live to be a hundred years old, from her apparent sound health and great activity of mind and body. How old was she?” “Franz assured me,” replied Albert, “that she was sixty-six years old. But she has not died of old age, but of grief; it appears that since the death of the marquis, which affected her very deeply, she has not completely recovered her reason.” “But of what disease, then, did she die?” asked Debray. “It is said to have been a congestion of the brain, or apoplexy, which is the same thing, is it not?” “Nearly.” “It is difficult to believe that it was apoplexy,” said Beauchamp. “Madame de Saint-Méran, whom I once saw, was short, of slender form, and of a much more nervous than sanguine temperament; grief could hardly produce apoplexy in such a constitution as that of Madame de Saint-Méran.” “At any rate,” said Albert, “whatever disease or doctor may have killed her, M. de Villefort, or rather, Mademoiselle Valentine,—or, still rather, our friend Franz, inherits a magnificent fortune, amounting, I believe, to 80,000 livres per annum.” “And this fortune will be doubled at the death of the old Jacobin, Noirtier.” “That is a tenacious old grandfather,” said Beauchamp. “Tenacem propositi virum. I think he must have made an agreement with death to outlive all his heirs, and he appears likely to succeed. He resembles the old Conventionalist of ’93, who said to Napoleon, in 1814, ‘You bend because your empire is a young stem, weakened by rapid growth. Take the Republic for a tutor; let us return with renewed strength to the battle-field, and I promise you 500,000 soldiers, another Marengo, and a second Austerlitz. Ideas do not become extinct, sire; they slumber sometimes, but only revive the stronger before they sleep entirely.’” “Ideas and men appeared the same to him,” said Albert. “One thing only puzzles me, namely, how Franz d’Épinay will like a grandfather who cannot be separated from his wife. But where is Franz?” “In the first carriage, with M. de Villefort, who considers him already as one of the family.” Such was the conversation in almost all the carriages; these two sudden deaths, so quickly following each other, astonished everyone, but no one suspected the terrible secret which M. d’Avrigny had communicated, in his nocturnal walk to M. de Villefort. They arrived in about an hour at the cemetery; the weather was mild, but dull, and in harmony with the funeral ceremony. Among the groups which flocked towards the family vault, Château-Renaud recognized Morrel, who had come alone in a cabriolet, and walked silently along the path bordered with yew-trees. “You here?” said Château-Renaud, passing his arms through the young captain’s; “are you a friend of Villefort’s? How is it that I have never met you at his house?” “I am no acquaintance of M. de Villefort’s,” answered Morrel, “but I was of Madame de Saint-Méran.” Albert came up to them at this moment with Franz. “The time and place are but ill-suited for an introduction.” said Albert; “but we are not superstitious. M. Morrel, allow me to present to you M. Franz d’Épinay, a delightful travelling companion, with whom I made the tour of Italy. My dear Franz, M. Maximilian Morrel, an excellent friend I have acquired in your absence, and whose name you will hear me mention every time I make any allusion to affection, wit, or amiability.” Morrel hesitated for a moment; he feared it would be hypocritical to accost in a friendly manner the man whom he was tacitly opposing, but his oath and the gravity of the circumstances recurred to his memory; he struggled to conceal his emotion and bowed to Franz. “Mademoiselle de Villefort is in deep sorrow, is she not?” said Debray to Franz. “Extremely,” replied he; “she looked so pale this morning, I scarcely knew her.” These apparently simple words pierced Morrel to the heart. This man had seen Valentine, and spoken to her! The young and high-spirited officer required all his strength of mind to resist breaking his oath. He took the arm of Château-Renaud, and turned towards the vault, where the attendants had already placed the two coffins. “This is a magnificent habitation,” said Beauchamp, looking towards the mausoleum; “a summer and winter palace. You will, in turn, enter it, my dear d’Épinay, for you will soon be numbered as one of the family. I, as a philosopher, should like a little country-house, a cottage down there under the trees, without so many free-stones over my poor body. In dying, I will say to those around me what Voltaire wrote to Piron: ‘Eo rus, and all will be over.’ But come, Franz, take courage, your wife is an heiress.” “Indeed, Beauchamp, you are unbearable. Politics has made you laugh at everything, and political men have made you disbelieve everything. But when you have the honor of associating with ordinary men, and the pleasure of leaving politics for a moment, try to find your affectionate heart, which you leave with your stick when you go to the Chamber.” “But tell me,” said Beauchamp, “what is life? Is it not a halt in Death’s anteroom?” “I am prejudiced against Beauchamp,” said Albert, drawing Franz away, and leaving the former to finish his philosophical dissertation with Debray. The Villefort vault formed a square of white stones, about twenty feet high; an interior partition separated the two families, and each apartment had its entrance door. Here were not, as in other tombs, ignoble drawers, one above another, where thrift bestows its dead and labels them like specimens in a museum; all that was visible within the bronze gates was a gloomy-looking room, separated by a wall from the vault itself. The two doors before mentioned were in the middle of this wall, and enclosed the Villefort and Saint-Méran coffins. There grief might freely expend itself without being disturbed by the trifling loungers who came from a picnic party to visit Père-Lachaise, or by lovers who make it their rendezvous. The two coffins were placed on trestles previously prepared for their reception in the right-hand crypt belonging to the Saint-Méran family. Villefort, Franz, and a few near relatives alone entered the sanctuary. As the religious ceremonies had all been performed at the door, and there was no address given, the party all separated; Château-Renaud, Albert, and Morrel, went one way, and Debray and Beauchamp the other. Franz remained with M. de Villefort; at the gate of the cemetery Morrel made an excuse to wait; he saw Franz and M. de Villefort get into the same mourning-coach, and thought this meeting forboded evil. He then returned to Paris, and although in the same carriage with Château-Renaud and Albert, he did not hear one word of their conversation. As Franz was about to take leave of M. de Villefort, “When shall I see you again?” said the latter. “At what time you please, sir,” replied Franz. “As soon as possible.” “I am at your command, sir; shall we return together?” “If not unpleasant to you.” “On the contrary, I shall feel much pleasure.” Thus, the future father and son-in-law stepped into the same carriage, and Morrel, seeing them pass, became uneasy. Villefort and Franz returned to the Faubourg Saint-Honoré. The procureur, without going to see either his wife or his daughter, went at once to his study, and, offering the young man a chair: “M. d’Épinay,” said he, “allow me to remind you at this moment,—which is perhaps not so ill-chosen as at first sight may appear, for obedience to the wishes of the departed is the first offering which should be made at their tomb,—allow me then to remind you of the wish expressed by Madame de Saint-Méran on her death-bed, that Valentine’s wedding might not be deferred. You know the affairs of the deceased are in perfect order, and her will bequeaths to Valentine the entire property of the Saint-Méran family; the notary showed me the documents yesterday, which will enable us to draw up the contract immediately. You may call on the notary, M. Deschamps, Place Beauveau, Faubourg Saint-Honoré, and you have my authority to inspect those deeds.” “Sir,” replied M. d’Épinay, “it is not, perhaps, the moment for Mademoiselle Valentine, who is in deep distress, to think of a husband; indeed, I fear——” “Valentine will have no greater pleasure than that of fulfilling her grandmother’s last injunctions; there will be no obstacle from that quarter, I assure you.” “In that case,” replied Franz, “as I shall raise none, you may make arrangements when you please; I have pledged my word, and shall feel pleasure and happiness in adhering to it.” “Then,” said Villefort, “nothing further is required. The contract was to have been signed three days since; we shall find it all ready, and can sign it today.” “But the mourning?” said Franz, hesitating. “Don’t be uneasy on that score,” replied Villefort; “no ceremony will be neglected in my house. Mademoiselle de Villefort may retire during the prescribed three months to her estate of Saint-Méran; I say hers, for she inherits it today. There, after a few days, if you like, the civil marriage shall be celebrated without pomp or ceremony. Madame de Saint-Méran wished her daughter should be married there. When that is over, you, sir, can return to Paris, while your wife passes the time of her mourning with her mother-in-law.” “As you please, sir,” said Franz. “Then,” replied M. de Villefort, “have the kindness to wait half an hour; Valentine shall come down into the drawing-room. I will send for M. Deschamps; we will read and sign the contract before we separate, and this evening Madame de Villefort shall accompany Valentine to her estate, where we will rejoin them in a week.” “Sir,” said Franz, “I have one request to make.” “What is it?” “I wish Albert de Morcerf and Raoul de Château-Renaud to be present at this signature; you know they are my witnesses.” “Half an hour will suffice to apprise them; will you go for them yourself, or shall you send?” “I prefer going, sir.” “I shall expect you, then, in half an hour, baron, and Valentine will be ready.” Franz bowed and left the room. Scarcely had the door closed, when M. de Villefort sent to tell Valentine to be ready in the drawing-room in half an hour, as he expected the notary and M. d’Épinay and his witnesses. The news caused a great sensation throughout the house; Madame de Villefort would not believe it, and Valentine was thunderstruck. She looked around for help, and would have gone down to her grandfather’s room, but on the stairs she met M. de Villefort, who took her arm and led her into the drawing-room. In the anteroom, Valentine met Barrois, and looked despairingly at the old servant. A moment later, Madame de Villefort entered the drawing-room with her little Edward. It was evident that she had shared the grief of the family, for she was pale and looked fatigued. She sat down, took Edward on her knees, and from time to time pressed this child, on whom her affections appeared centred, almost convulsively to her bosom. Two carriages were soon heard to enter the courtyard. One was the notary’s; the other, that of Franz and his friends. In a moment the whole party was assembled. Valentine was so pale one might trace the blue veins from her temples, round her eyes and down her cheeks. Franz was deeply affected. Château-Renaud and Albert looked at each other with amazement; the ceremony which was just concluded had not appeared more sorrowful than did that which was about to begin. Madame de Villefort had placed herself in the shadow behind a velvet curtain, and as she constantly bent over her child, it was difficult to read the expression of her face. M. de Villefort was, as usual, unmoved. The notary, after having, according to the customary method, arranged the papers on the table, taken his place in an armchair, and raised his spectacles, turned towards Franz: “Are you M. Franz de Quesnel, baron d’Épinay?” asked he, although he knew it perfectly. “Yes, sir,” replied Franz. The notary bowed. “I have, then, to inform you, sir, at the request of M. de Villefort, that your projected marriage with Mademoiselle de Villefort has changed the feeling of M. Noirtier towards his grandchild, and that he disinherits her entirely of the fortune he would have left her. Let me hasten to add,” continued he, “that the testator, having only the right to alienate a part of his fortune, and having alienated it all, the will will not bear scrutiny, and is declared null and void.” “Yes.” said Villefort; “but I warn M. d’Épinay, that during my life-time my father’s will shall never be questioned, my position forbidding any doubt to be entertained.” “Sir,” said Franz, “I regret much that such a question has been raised in the presence of Mademoiselle Valentine; I have never inquired the amount of her fortune, which, however limited it may be, exceeds mine. My family has sought consideration in this alliance with M. de Villefort; all I seek is happiness.” Valentine imperceptibly thanked him, while two silent tears rolled down her cheeks. “Besides, sir,” said Villefort, addressing himself to his future son-in-law, “excepting the loss of a portion of your hopes, this unexpected will need not personally wound you; M. Noirtier’s weakness of mind sufficiently explains it. It is not because Mademoiselle Valentine is going to marry you that he is angry, but because she will marry, a union with any other would have caused him the same sorrow. Old age is selfish, sir, and Mademoiselle de Villefort has been a faithful companion to M. Noirtier, which she cannot be when she becomes the Baroness d’Épinay. My father’s melancholy state prevents our speaking to him on any subjects, which the weakness of his mind would incapacitate him from understanding, and I am perfectly convinced that at the present time, although, he knows that his granddaughter is going to be married, M. Noirtier has even forgotten the name of his intended grandson.” M. de Villefort had scarcely said this, when the door opened, and Barrois appeared. “Gentlemen,” said he, in a tone strangely firm for a servant speaking to his masters under such solemn circumstances,—“gentlemen, M. Noirtier de Villefort wishes to speak immediately to M. Franz de Quesnel, baron d’Épinay.” He, as well as the notary, that there might be no mistake in the person, gave all his titles to the bridegroom elect. Villefort started, Madame de Villefort let her son slip from her knees, Valentine rose, pale and dumb as a statue. Albert and Château-Renaud exchanged a second look, more full of amazement than the first. The notary looked at Villefort. “It is impossible,” said the procureur. “M. d’Épinay cannot leave the drawing-room at present.” “It is at this moment,” replied Barrois with the same firmness, “that M. Noirtier, my master, wishes to speak on important subjects to M. Franz d’Épinay.” “Grandpapa Noirtier can speak now, then,” said Edward, with his habitual quickness. However, his remark did not make Madame de Villefort even smile, so much was every mind engaged, and so solemn was the situation. “Tell M. Nortier,” resumed Villefort, “that what he demands is impossible.” “Then, M. Nortier gives notice to these gentlemen,” replied Barrois, “that he will give orders to be carried to the drawing-room.” Astonishment was at its height. Something like a smile was perceptible on Madame de Villefort’s countenance. Valentine instinctively raised her eyes, as if to thank heaven. “Pray go, Valentine,” said; M. de Villefort, “and see what this new fancy of your grandfather’s is.” Valentine rose quickly, and was hastening joyfully towards the door, when M. de Villefort altered his intention. “Stop,” said he; “I will go with you.” “Excuse me, sir,” said Franz, “since M. Noirtier sent for me, I am ready to attend to his wish; besides, I shall be happy to pay my respects to him, not having yet had the honor of doing so.” “Pray, sir,” said Villefort with marked uneasiness, “do not disturb yourself.” “Forgive me, sir,” said Franz in a resolute tone. “I would not lose this opportunity of proving to M. Noirtier how wrong it would be of him to encourage feelings of dislike to me, which I am determined to conquer, whatever they may be, by my devotion.” And without listening to Villefort he arose, and followed Valentine, who was running downstairs with the joy of a shipwrecked mariner who finds a rock to cling to. M. de Villefort followed them. Château-Renaud and Morcerf exchanged a third look of still increasing wonder.
