An honor and a privilege. Here to serve

The final 100 ETHSecurity Badge holders are in!
That brings us to 200 security experts, guiding how TheDAO allocates its funds and also coordinating behind the scenes to make Ethereum safer.
Big thanks to everyone who engaged with the process and helped shape it, and to @bonfiresai for building the tooling that made it possible.

This is how easy it is to lend @PayPal's PYUSD against @OndoFinance tokenised stocks on Euler.

The most audited protocols of all time as of 2025:
1. @1inch - 120 audits
2. @LidoFinance – 70 audits
3. @eulerfinance – 45 audits
4. @aave – 30 audits
If I were running a Web3 project, I’d study these teams closely.

Wrote a script to check at the GitHub org level for the ongoing NPM supply chain attack. It scans all repos lockfiles for the compromised packages. gist.github.com/erik1o6/b533…

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
11 Jun 2025
EulerSwap passed its biggest security test.
As with v2, EulerSwap adopted a multi-layer security strategy:
→ 5 audits (0 critical/high findings)
→ Fuzz testing since early development days
→ A $500K CTF (with no devs cracking the code)
Bug bounty on Cantina: Coming soon.

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.

I often get asked what tools I use for web app pentesting, and people are surprised when I say it's 99% Burp Suite Pro. Here's why...

The stakes have been raised yet again! 🪐 @eulerfinance has upped the bug bounty on Cantina to $7.5M.
Following unprecedented growth in the USL vaults, @usualmoney is boosting security by adding $2.5M in USUAL tokens to Euler's bounty for bugs affecting USL vaults.
This massive reward is now available to security researchers uncovering critical vulnerabilities in their protocol.
Bounty link below.

As Euler's TVL grows, so does our focus on security.
Euler has always valued and worked closely with the security community, and we're looking to expand on that even more.
26 Feb 2025
A never ending focus on security.
The Euler v2 bug bounty has been raised from $1M to $5M on @cantinaxyz.
Security will always be first and with this we aim to attract more researchers to examine Euler's code.

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
