Keep in mind

  • The network fee is noticeable: for small orders add a cheaper network to the checkout, such as BEP-20, TON or Solana.

Instant delivery

The payment.confirmed webhook is the signal to deliver the purchase on your server.

Small orders

Solana, TRON and BSC are a good fit for purchases of a couple of dollars.

USDC and USDT

The two main stablecoins on one network — customers pay with whatever they have.

For game servers, a handy setup is orderId = player nickname plus item id: the webhook handler delivers the purchase immediately, with no manual checks.

Network fees on Ethereum are higher than on TRON or BSC, so it makes sense to offer ERC-20 for large payments and B2B invoices, with alternatives on other networks for small orders. One payment page can show several options.

Recommended coin set for games and donations

To cover most customers, enable on the checkout page: USDT BEP-20, USDT on TON, USDT and USDC on Solana. The customer picks the network, and every payment lands on one project balance.

One request to create a payment

The response contains the address, the exact amount and a link to a ready-made payment page. Status updates arrive via HMAC-signed webhooks.
