One engine · Three flows
Accept crypto. Sell crypto. Pay out anywhere.
One programmable engine powers three flows — accept stablecoins for crypto-native businesses, let users buy crypto at checkout, and payout to any rail, anywhere, anytime.
One API
Programmable corridors. Shipped in one afternoon.
One request creates a quote, picks the optimal chain, executes the on-ramp, bridges through stablecoin, and settles into the contact's local fiat account. Idempotent. Webhook-driven.
- Smart routing across USDC/USDT
- Real-time webhooks on every state change
- Double-entry ledger — audit-ready from day one
