Which coins and networks?

USDT and USDC. The checkout lists the networks it accepts at the moment you pay and shows the address and the exact amount for each; send on the network you selected.

How long until the balance credits?

As soon as the payment confirms on its network, usually within a few minutes. Alipay and WeChat Pay credit at once.

You pay the network fee for the transfer; the amount credited is the amount received. The checkout shows the exact total before you send.

Do I need to verify my identity?

No. An email address opens the account; no identity check, no card on file.

Can I pay from an exchange?

Yes, as long as the exchange sends on a network the checkout lists. Withdrawals from an exchange can take longer to confirm.

What if I send the wrong network or asset?

Funds sent on an unlisted network or in another asset may be unrecoverable. Check the network and the asset on the checkout before you send.
