1. Select the asset in checkout
Use only a cryptocurrency currently offered by OxaPay for that payment; wallet balances with a similar name are not interchangeable.
2. Match the network character for character
TRON, Ethereum, BNB Smart Chain and other networks can carry similarly named tokens but use different rails.
3. Send the exact amount before expiry
Account for wallet or exchange withdrawal fees so the address receives the requested amount, not a smaller net amount.
4. Keep the transaction ID
After broadcasting, return to the order page and monitor confirmations. Save the transaction ID for support, but never share wallet credentials.
5. Respect the invoice lifetime and exact route
Open one live invoice and finish the transfer before its displayed expiry. Copy the destination from that session, compare the first and last characters, and confirm that the sending wallet supports the named network. Include any memo or tag only when the invoice explicitly supplies one. If the invoice expires, return to the order page for the supported next step; do not reuse an address or amount from a screenshot, old tab, message or previous order.
6. Reconcile before taking another action
If status appears inconsistent, do not send a second payment or switch networks. Preserve the live invoice, USV reference, transaction ID, network, sent amount, timestamp and block-explorer link, then use order tracking. Support can compare these facts with the signed provider event and expected invoice. A wallet screenshot alone is not final proof, and no one needs a seed phrase or private key to investigate.
Frequently asked questions
What if I choose the wrong network?
Do not send. Change the selection or create a new valid session; funds sent on a wrong network may be unrecoverable.
Who pays the network fee?
The sender does; make sure fees do not reduce the amount OxaPay must receive.
Can I pay from an exchange?
Only if it supports the exact asset, network and withdrawal amount; exchange batching or delays can outlast the payment window.
Can I reuse an OxaPay address from an earlier invoice?
Do not assume so. Use only the address, asset, network, amount and memo shown in the current unexpired session. If it expires, follow the order page instead of sending from saved details.
