Verify the destination
Open billing from the verified site and check the complete invoice. Confirm the asset, network, amount, expiry and address. Clipboard malware and impersonation can change a destination while leaving the surrounding page convincing.
Keep wallet secrets separate
Support needs an invoice number or transaction identifier, not a seed phrase or private key. Do not enter recovery words into a hosting dashboard, send them by email or paste them into a support conversation.
Understand fees and confirmation
A wallet or exchange may subtract a fee from the amount it sends. That can leave an invoice underpaid. Network congestion and exchange processing can delay settlement; check the stated confirmation policy before assuming the payment failed.
Retain a useful receipt
Keep the invoice, transaction identifier, asset and network with your own records. Share only the minimum needed for support, since a transaction identifier can reveal public activity. Review cancellation and refund rules before paying.
