What it means
The blockchain records confirmed transactions publicly. Wallets control spending through private keys; a service accepting BTC does not need your recovery phrase. Network fees and confirmation timing vary.
For hosting
Check whether the invoice requests an on-chain payment or a separately supported Lightning payment. Keep the network, amount and invoice expiry clear.
Which payment route does the invoice name?
Confirm whether it is Bitcoin on-chain or a separately supported Lightning flow. Match the amount and expiry, and do not send a second payment until the first outcome is understood.
