tl;dr SSTORE is one of the most expensive EVM opcodes. A savvy developer always optimizes their smart contract to use SSTORE in the most efficient manner. However, there’s a catch buried in EIPs that nobody talks about. Or at least, I haven’t encountered any information about it until today. tl;dr, Read the Conclusion. Background There are a ton of resources out there that can teach you how to reduce and optimize the gas consumption of your smart contract. Recently, I went through some of th

Euler is going multichain. This is a recent development, and it reflects Euler’s commitment to increasing access to open and fair financial tooling. In doing so, Euler will be available to a wider number of users who will be able to transact with more assets than ever before. Why multichain? Euler has been exclusively on Ethereum mainnet since its deployment, and the DAO has decided that the time is right to deploy on other chains. This decision is supported by both pull factors from other ch

________________________________________ Summary: * Existing liquidation structures are wasteful, liquidating large positions and contributing to gas wars. New developments must occur in the liquidation engine space to reduce bad debt in DeFi, which sits at ~2.5% on mainnet. * Euler mitigates gas usage and constrains MEV bots by offering sliding discounts to liquidators, and multiplying the discounts for liquidators with deposits in Euler. This forms a dutch auction. * Euler’s liquidators c

Getting generalised or specific information about Euler is straightforward, and users should consider this piece as a starting point to collect data. This could be either manual data collection or enjoying the dashboards Euler contributors have already made. In addition, users may seek to utilize Euler’s subgraph to assist in data collection. All of these data sources are FREE (at the base level). Other data sources such as Nansen, Parsec etc. are also available, but they are not free. This pos

Euler Finance’s frontend has had a significant improvement to the health monitor! Thanks to the hard work of contributors, users can clearly understand the risk of other events while having no effect on a position. Given that this is a simulation (and has no effect on the user’s existing position), this will assist a significant refinement in risk management. Thanks to this boost to the Health Monitor, Users can now have a much clearer idea of what conditions might be met in order for their acc

Halborn Security was recently asked by Euler to assess the protocol’s smart contracts over a month period, from 8th May to 4th June, as an additional layer of security and assurance, in addition to a previous audit by Solidified and ZK Labs. The team at Halborn found an overall satisfactory result which has now been made publicly available on Github here. The Halborn team ranked their risk assessment methodology by measuring the likelihood of a security incident and the impact of such an incid

Users of non-custodial lending protocols need to understand factors like oracle manipulation and make a judgement call on when it is safe to use a given oracle. Explained here is how and why Uniswap’s oracles are sometimes risky, and introduce a new price oracle rating tool on the Euler UI to help users understand and manage these risks. TL;DR: lending into anything with an oracle rating below B is extremely risky! Introduction Euler is a non-custodial lending protocol which allows its users

A tool was released which allows users to simulate and quantify attack risks on Uniswap V3 TWAP price oracles. Introduction An increasing number of DeFi protocols, Euler included, rely on Uniswap v3 price oracles. These oracles take the average of the spot price on Uniswap v3 for an asset over some specified period in the past; that is, they give a time-weighted average price (TWAP) for an asset, rather than just a current price. Although truly decentralized, and much more resilient than the

The ImmuneFi Bug Bounty programme aims to strengthen Euler protocol’s security while boosting collaboration with the greater DeFi ecosystem as part of an insurance partnership with Sherlock Protocol. Euler protocol is kicking off a $1 million bug bounty programme with ImmuneFi as part of a $10 million insurance partnership with Sherlock Protocol. This initiative will center on covering Euler protocol’s smart contracts and incentivise ethical reporting of potential security vulnerabilities or e
