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
Use this network to test your integration before accepting production payments.
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.
Testnet tokens have no monetary value. Testnet activity is not a production payment.

Questions about testing
What is a testnet?
A testnet is a full copy of a blockchain that runs on coins with no monetary value. It behaves like the real network — same addresses, same confirmations, same webhooks — so an integration can be proven before any real money is involved.
Do testnet coins have any value?
None. Testnet tokens cannot be sold or spent anywhere, and testnet activity is never a production payment. That is exactly the point: a mistake made on a testnet costs you nothing.
Does testing count against my plan?
No. Testnet is free and unlimited on every plan, including the free one, so integrating and testing never consume capacity. Only confirmed mainnet payments count as transactions.
Which networks can I test on?
6 test networks covering 5 network families, each behaving like its mainnet twin, with confirmation depths from 1 to 32 blocks exactly as in production. Every family we settle on has a testnet, so you rehearse the same derivation and detection path you will use for real.
