I don't like self-promotion, but ...😅 I'm happy with the work I did for Uniswap v4. Certora's public report highlights interesting properties proven, and 5 / 11 of them are mine. github.com/Certora/uniswa…

@0x00ffDa proved a critical slippage control property which mathematically guarantees that users can never profit from position minting or exceed specified slippage bounds - key safety measures for Uniswap 🛡️

I love the concept behind @certora's Concordance, an elegant blend of AI and formal verification. Feed it a complex, assembly-optimized function: 1. It uses AI to generate a simplified, readable version. 2. It proves their equivalence. certora.com/blog/concordan…

alright, after a week of work you can now fully simulate Safe transactions _locally_ before signing and verify the transaction hashes in parallel using my `safe-tx-hashes-util` with a single command (use the `--simulate flag` simply). This lets you check exactly how the transaction will execute before you sign. Everything is local. Everything what is executed is printed in the terminal. Transparency at all cost. You trust your RPC provider here so use a trusted endpoint or the preferred solution of running your own node. I know many still do not believe me but local-first, cli-based verification is the way to go. Not hosted UIs. My verification script is _one_ fucking Bash file. Everyone can audit it by looking at exactly one file. No dependency bloat.
