Introduction
Rasto Business turns a bank payment into an on-chain stablecoin delivery, and gives your customers non-custodial wallets to hold the result.
Rasto Business is a REST API for moving money between bank accounts and stablecoins. You onboard your customers, we verify them and issue each one a dedicated USD bank account, and every payment that lands on it is converted and delivered on-chain to the destination you chose. Your customers can also hold non-custodial wallets that only your key can send from.
At launch, USD arrives over ACH and Fedwire, and USDC and USDT are delivered on Solana. For the full matrix, see Coverage.
