Happy to announce that 33Audits is one of the whitelisted service providers for @UniswapFND. We've been involved in building and auditing hooks for over a year now and are excited to help secure Defi's future and the narrative continues to grow.
It's pretty crazy being on this
Our team just finished an audit of a GeometricMeanOracle built using Uniswap hooks, and we found an issue where a user with enough capital can manipulate the prices being stored. The interesting part of this issue is that it is a relatively unique finding related to v4 hooks.
this bug was recently found in a sherlock contest and paid $2500, i discussed a similar issue in my article and what to look out for when auditing/developing hooks
github.com/sherlock-audit…
a while back i wrote an article on some security-related nuances when building Uniswap v4 hooks. never shared it publicly but this ended up leading to me finding two high vulnerabilities in various private audits i did
33audits.hashnode.dev/uniswap-v4-sec…
Our team completed a review of @vii_finance last week, and I'm happy to say the codebase is extremely solid and very well written. This team is extremely base, and it's clear they understand the importance of keeping things simple when writing Solidity.
Looking forward to
