Euler v2 turns 1 today. No way we could've done it alone. Incredible things happen when you don't give up.
Grateful to all the security researchers who participated in the live CTF
Grateful to all the security researchers who participated in the live CTF
Introducing a milestone in protocol security validation. 🪐 We've teamed up with @eulerfinance to launch a $500,000 mainnet CTF, featuring live Ethereum contracts with real liquidity. The challenge begins tomorrow, June 3 at 10:00 AM ET. Here's what you need to know.
We like capture the flag (CTF) competitions at Euler. Aside from being a great security excercise, inviting the brightest minds in web3 security to come try to take your money is a lot of fun. Study the EulerSwap contracts.
1/ Introducing EulerSwap A smarter DEX with lending-boosted yield, deeper just-in-time liquidity, and native support for LP positions as collateral. Supercharged by Euler lending infra.

It’s time. Euler is now live on @base.
It was so cool of Bangkok to set off fireworks for Euler hitting 60M
Performing a state check after actions is a strong security practice This approach seems to address >70% of potential bugs Even if other functions create an invalid state, the final state check will catch it A great example can be seen in @eulerfinance github.com/euler-xyz/ethe…
1/ It's time to distribute real token rewards. Introducing rEUL (“ROYAL”) - a 1:1 locked version of EUL tokens to reward users of Euler.
📢 New panel just dropped: Building & Securing a Successful DeFi Protocol We're bringing together 4 top security engineers from leading DeFi protocols for an insightful discussion on the challenges of building and maintaining secure crypto protocols—where billions of dollars are…
Shutout to @eulerfinance to having one of the best documented @CertoraInc specs in their repo. This makes it super easy for anyone to understand the property of the protocol. github.com/euler-xyz/ethe…
It's alive!!!!
The final boss of DeFi security has entered the chat. Today we kick off a $~3.5 million CTF challenge with @HatsFinance. For details and legal disclaimers, read the blog below. Alongside the CTF competition and ongoing after it concludes, we’re also launching a bug bounty with…
