How it works

From API call to settled payment

Create invoice

One API call returns a checkout URL, deposit address, and optional chat-ready payment text.

Customer pays

Buyer picks coin and network in your widget, then sends crypto to a unique smart-account address.

You get notified

We detect the deposit on-chain, update your ledger, and POST a signed webhook to your server.

Average integration time: under 30 minutes

Platform
