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. Ease of Integration Data Vault's structure simplifies the integration of data from disparate sources, providing a consistent and unified view across the organization. Its design enables the efficient incorporation of new data sources, facilitating a more comprehensive data strategy. Improved Data Quality and Governance The granular approach of Data Vault modeling enhances data quality, as each piece of information is stored in detail with clear lineage. This structure also supports better data governance practices, with built-in mechanisms for compliance, auditability, and data security. Enhanced Auditability and Compliance Features Data Vault's inherent tracking of historical data and its ability to capture metadata make it exceptionally well-suited for meeting audit and compliance requirements. The model's design ensures that changes are recorded in a way that supports traceability and accountability, essential for regulatory compliance. These benefits make Data Vault modeling an attractive option for organizations looking to build robust, scalable, and compliant data warehousing solutions that can adapt to future needs and challenges. Planning and Implementing a Data Vault Model Implementing a Data Vault model in your organization requires careful planning and a structured approach. Here's a step-by-step guide to help you get started: Step-by-Step Guide on Starting with Data Vault Modeling : Begin by gathering detailed business requirements and understanding the data needs of your organization. This will guide the design of your Data Vault model. Understand Your Business Requirements : Evaluate your existing data infrastructure to determine how well it can support a Data Vault architecture. Consider factors like storage capacity, processing power, and existing data integration processes. Assess Your Current Data Infrastructure : Based on your requirements, start designing your Data Vault model. Identify the Hubs, Links, and Satellites that will form the structure of your data warehouse. Design Your Data Vault Model : Choose the tools and technologies that best support Data Vault modeling. This may include specific database platforms, ETL tools, and data modeling software. Select the Right Tools and Technologies : Begin the construction of your Data Vault by creating the Hubs, Links, and Satellites. Implement data loading processes to populate your Data Vault. Build and Deploy Your Data Vault : As your data needs evolve, continue to expand and refine your Data Vault model by adding new Hubs, Links, and Satellites as required. Iterate and Expand Key Considerations: Infrastructure, Tools, and Team Skills : Ensure your infrastructure can handle the volume and velocity of data expected. Scalability and performance are key. Infrastructure : Select tools that are compatible with Data Vault modeling principles and can automate parts of the process to improve efficiency.

Team Skills Data Vault Project Lifecycle The lifecycle of a Data Vault project encompasses several phases, from initial planning and design to deployment and maintenance. It's important to adopt an iterative approach, allowing for continuous improvement and adaptation to new 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.

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.
