How the payment works

Payments settle directly to your merchant-controlled wallet. Unheld does not hold the funds or private keys.

Invoices track detected, confirming, paid, underpaid and overpaid states using exact on-chain amounts.

Create an invoice through the API, show the hosted payment page, then use signed webhooks to update your order.

What to watch for

The payer sends the network fee to the blockchain, not to Unheld.

Send only an enabled asset on the exact network shown. A wrong-network transfer may be unrecoverable.

Questions about this list

Which cryptocurrencies can I accept?

9 assets across 9 mainnet networks, all listed in the table above. The list is generated from the running product rather than maintained by hand, so if an asset appears here it can take a payment today.

Can I accept the same stablecoin on more than one network?

Yes — 3 of these assets settle on several networks each, and every invoice names the exact one. They are not interchangeable: the same stablecoin on two networks is two different things, and a transfer sent on the wrong one may be unrecoverable.

How many confirmations before a payment counts as paid?

Between 1 and 32 blocks depending on the network, and each network's own threshold is shown above. The count is a security parameter set per network, not one figure applied everywhere.

Can I test before accepting real money?

Yes — 6 test networks behave exactly like their mainnet twins and cost nothing to use. You can run the whole flow, including detection and webhooks, before a single real payment is involved.
