fricoben(@Fricoben):We built Verity, an open-source formally verified smart contract compiler in Lean 4, granted by @ethereumfndn and @thedaofund (+ @wintermute_t) to enable us to formally verify all protocols with a simple method: 1- Model the contract in Verity 2- Write the spec the contract must follow 3- Agents write the maths proofs that this implementation matches the specs 4- Lean's kernel checks the proof holds
