How to choose a smart contract audit firm
Weigh five things: track record depth (audits completed and scope), chain and language coverage, finding severity distribution (a higher critical/high/medium ratio signals deeper review), incident history of protocols they've audited, and team responsiveness. Match the firm to your codebase: a Solidity-heavy firm may not be the right fit for Rust or Move.
