We audited Reclaim protocol's ChaCha20 circuits, diving deep into bit-level operations for a secure and efficient design. After a few iterations, we switched from a word-based to a bit-focused circuit approach, achieving a 10% enhancement in performance and size. We used Circom for implementation, with a focus on Groth16 system constraints. Our findings led Reclaim to revamp their strategy, honing in on bitwise logic for an effective flow without costly re-encodings. Curious about the technical journey and the final audit insights? We’ve got the details covered!
