A payments gateway already in production. Your merchants, your fee.
Hosted checkout, payment links, REST API with HMAC-signed webhooks, sandbox, SDKs, a merchant panel and an operator console, on the same custody core as the exchange. Merchants settle the moment the chain confirms; you set the fee.

From checkout to an approved payout.
The path a stablecoin payment takes through the gateway, as your merchant's server sees it.
- The merchant's server creates an invoice and gets a checkout URL.
- The buyer pays from any wallet; the watcher sees it in the mempool.
- Confirmations accumulate to the depth set for the chain.
- An HMAC-signed webhook marks the order paid.
- The merchant balance grows and payouts follow your approval rules.
- No chargebacks · settlement in minutes · your fee on every payment
