Mercury is the US startup bank — venture-backed companies, YC alumni, and many Web3 teams hold their fiat there. For a Web3 startup, the GL needs to reconcile Mercury (fiat) and on-chain wallets (crypto) under one chart of accounts. The Wag3s integration ingests Mercury via the official API, classifies fiat transactions, and produces unified reporting.
