Building on the success of our recent code competition with 602 researchers, we're thrilled to continue our collaboration with Cantina to further fortify Euler v2's contracts and launch a $1 million bug bounty programme, now live. Over the past year, we've worked closely with numerous security teams and individual researchers whose insights have helped us refine and strengthen both Euler v2’s contract design and security. The goal of this programme is to continue to work with the security commu

Liquidity begets more liquidity “The problem with Uniswap and Euler trying to be all, like, modular, is that liquidity will fragment if there’s loads of pools for each type of asset.” Here’s why this is a flawed perspective. Left to its own devices, liquidity typically begets more liquidity. Whenever there are redundant options for where liquidity can flow to, the least liquid options often suffer. This phenomenon plays out in nature just as much as it does in economics. It’s why you seldom

Security came first in every step of building Euler v2.  The vision for transitioning Euler into a modular protocol dates back to 2022. Since then, various code designs have been explored as proof of concepts long before work officially began on what will be launched in the very near future. As we head toward that milestone, we’re proud to share today that Euler v2 has undergone one of the most expensive and comprehensive security processes for any DeFi protocol to-date. Roughly $4m was alloca

Introduction  Over-collateralisation is a powerful mechanism for allowing peer-to-peer (P2P) or peer-to-pool (P2P) lending in decentralised finance (DeFi). Lenders require borrowers to deposit more value in collateral than they take out in loans. This requirement helps ensure that there is always an incentive for borrowers to repay their loans. Where and how collateral is deposited can have a major impact on the capital efficiency of lending protocols. There are two main approaches protocols us

TL;DR: * Euler Vault Kit (EVK) and Euler Price Oracle code is made public today. * Auditors encouraged to begin familiarising themselves with the code ahead of $1.25m record-breaking Cantina code audit contest begins on May 20th. * Builders and integrators can begin learning how to create and connect together their own custom lending and borrowing vaults, or their own synthetic assets. * For further questions or inquiries about integrating with Euler, reach out to us on Discord or Telegram

Traditionally in DeFi, protocols have commonly directed accumulated fees straight into their treasury. However, this approach has revealed itself to be suboptimal, requiring active treasury management to consolidate all assets into a single currency. The conversion of fees into a single asset has been riddled with challenges, leading to issues such as MEV extraction, dependency on oracle services, and the necessity for ongoing oversight. This blog aims to explain Fee Flow, Euler’s approach to

We're excited to announce the largest security competition done in history with $1,250,000 in rewards up for grabs. The Euler v2 Code Audit Competition will be conducted in collaboration with Cantina, an industry-leading security marketplace incubated by Spearbit. As the largest audit competition in crypto history, this marks a significant milestone ahead of the upcoming launch of Euler v2 in the Ethereum mainnet. In the development of Euler V2, we are elevating the standards in every aspect wh

It’s official. Euler is relaunching! Today, we’re excited to unveil Euler v2— The Modular Lending Platform. Check out the Lite paper or read on below to find out more. Introduction Euler v2 is a modular lending platform that will have two main components at launch: 1) the Euler Vault Kit (EVK), which empowers builders to deploy and chain together their own customised lending vaults in a permissionless manner; and 2) the Ethereum Vault Connector (EVC), a powerful, immutable, primitive which g

Introduction Suppose a lending protocol allows borrowers to use USDC as collateral to take out loans of ETH. What is the maximum amount of ETH that can be borrowed with the USDC collateral? Asked in terms of protocol risk management, what is the correct loan-to-value (LTV) ratio the protocol should adopt for such a trade? A straightforward answer is that it is the LTV that maximises the risk/reward payoff for lenders. Unfortunately, knowing what this is at any given point in time is practical
