C-13: Fee added on top and amount matches exactly

IdentifierC-13

AppliedBefore funding (M3), Before any coin leaves your wallet

StatementYour wallet is configured to add the network fee on top of the amount rather than deduct it, and the figure sent matches the figure requested.

Grading criteria

PASSFee added on top, amount identical to the request.

PARTIALSlightly over the requested amount.

FAILFee deducted from the amount, so less arrived than requested.

COSTA shortfall smaller than the rounding on the price leaves an order unfunded. The cause is a wallet preference rather than anything either party did.

The setting that causes this

Wallets differ on one small behaviour. Some treat the figure you enter as the total leaving your balance and subtract the network fee from it, so slightly less arrives. Others add the fee on top, so the exact figure arrives. Neither is wrong and only one of them funds an order correctly.

Why it catches careful people

The amounts are tiny. An order sits unfunded over a difference smaller than the price rounding, and nothing about the wallet interface suggests anything went wrong. The transaction succeeded, it just delivered slightly less than the order required.

If you have already underpaid

Do not send a second payment to top it up before asking, since two partial deposits are harder to reconcile than one
Open a support message with the order reference and the exact amount sent
Wait for instructions rather than improvising a fix

If you overpaid

Usually the simpler case. The surplus generally lands on your balance and you withdraw it, which is why sending very slightly over is graded partial rather than fail. Raise it with support if it does not appear once confirmations complete.
