FAQ

Common questions

Quick answers before you integrate.

How does payment detection work?

Each invoice gets a unique deposit address. Our system monitors the blockchain and confirms payment automatically — customers never paste a transaction ID.

Which coins and networks are supported?

USDT, USDC, ETH, and BNB across Ethereum, BSC, Polygon, Arbitrum, Base, and Optimism — 17 network pairs in total.

What are the fees?

No monthly fee. A small percentage (default 0.5%) is charged per settled payment. High-volume merchants can request custom rates.

How do webhooks work?

When a payment is confirmed, we POST a signed payload to your webhook URL using HMAC-SHA256. Built-in retries help ensure delivery.

Can I embed checkout in my app?

Yes — hosted checkout page, modal embed via embed.js, iframe, or desktop WebView. Same flow everywhere: pick coin, pick network, pay.
