Payment gateway
Invoice in fiat while the customer pays in crypto. Each invoice gets its own temporary address, the rate is locked at creation, and the incoming transaction goes through AML screening.
You can name the payment currency and network upfront, or create the invoice with just an amount and let the buyer pick the network in a second request. The second flow suits you when you do not know in advance how the customer will pay.
The address is issued for a specific invoice and serves to identify the payment. On networks where a per-invoice address is not issued, a shared address with a memo is used, and the checkout page shows it to the buyer.
If less than the required amount arrives, the invoice moves to partially paid and waits for further transfers. Each deposit arrives as its own notification with the updated amount.
A payment can be returned to the sender in full or in part: a refund request is created against the invoice and confirmed in a separate step.
Pass the amount, currency and order number. You get back a payment address and the deadline until which the locked rate holds.
The checkout page fills in the address for the right network, shows a QR code and — where the network requires it — the memo.
After the required confirmations the invoice becomes paid. If the amount falls short, it stays partially paid and waits for the remainder.
With AML enabled the transaction is scored first. Then the funds are swept from the temporary address to your merchant wallet — the invoice’s final status.
The full list of assets, networks and limits lives on the supported assets page.

Create an account, fill in the project questionnaire and attach your company documents. Once reviewed, create a merchant: set your website, return URLs and the list of assets your customers will be able to pay with.
With a ready-made CMS module it takes about fifteen minutes: install the plugin and paste two keys. An API integration usually takes anywhere from a few hours to one business day.
The service fee is 1% of the incoming payment. It is deducted when funds move from the invoice’s temporary address to your merchant wallet, in the same token the buyer paid with. At higher volume the rate is negotiated individually. The network fee is charged separately.
The payable amount is calculated when the currency and network are chosen and locked until the invoice expires — the deadline arrives in the expires_at field. If the buyer misses it, the invoice is cancelled, and funds sent after cancellation are likely lost. To take the rate out of the equation entirely, invoice in stablecoins.
Where AML is enabled for the network, the transaction is scored before funds move to your merchant wallet. On a low-risk result the invoice proceeds automatically; on a high-risk one it stops at “awaiting AML decision”, where you can approve the credit or refund the sender. The report is available per invoice via the API.
We will help with the integration, match the terms to your volume, and advise which assets and networks are worth enabling at checkout.
