Sent the wrong amount for an order Common

Most shortfalls are not typing errors. They happen when the wallet deducts the network fee from the amount you entered rather than adding it on top, so slightly less arrives than the order expects.

If you sent too little

1. Do not send a second payment blindly, since that can create a second unmatched deposit
2. Open a support message with the order reference and the exact amount sent
3. Wait for instructions rather than improvising, because the order is recoverable and a guessed fix may not be

If you sent too much

Usually the simpler case. The surplus normally lands on your balance, and you withdraw it. Raise it with support if it does not appear once confirmations complete.

Why fees cause most of these

Wallets differ on one small setting. Some treat the figure you type as the amount to leave your balance, deducting the network fee from it, so slightly less arrives than you entered. Others add the fee on top, so the exact figure arrives. Neither is wrong, but the first quietly produces a shortfall on every order unless you account for it.

The amounts involved are tiny, which is exactly why it catches people. An order sits unfunded over a difference smaller than the rounding on the price, and the cause is a wallet preference rather than anything either party did.

What not to do

• Do not top up with a second payment before asking, since two partial deposits are harder to reconcile than one
• Do not assume a shortfall is theft, because the coin is on the chain and visible
• Do not round the amount down to something tidier than the figure requested
