Checkout tells you exactly what to send. Only one asset on one network counts: the **Send exactly**, **Network** and **Address** shown on the page.

## You sent too little

Send the rest to the **same address** before the timer ends. Transfers add up. If the timer already ended, contact the merchant with your Reference ID.

## You sent too much

Contact the merchant with your Reference ID and the transaction hash. Mayarin cannot decide whether an extra amount is returned to you.

## Your exchange took a fee out of the amount

Some exchanges deduct their withdrawal fee from what you send, so the payment arrives short. Withdraw a bit more than the total, or pay from a wallet you control. If it arrived short, send the difference to the same address before the timer ends.

## You sent a different asset

Only the asset shown on this payment counts. Anything else is not matched to your payment. Contact the merchant and your wallet or exchange provider, and share your Reference ID. Do not send again until you know where the first transfer is.

## You sent on a different network

Only the network shown counts. A transfer on another network does not match the payment, and the payment will expire. Sometimes funds sent on another network can still be recovered, but that depends on the case and is not guaranteed. Contact support with:

* your Reference ID

* the transaction hash

* the asset, the network you used, and the network you should have used

Do not send the payment again before you hear back, or you may pay twice.

## How to avoid it

Compare the network name on the payment page with the network in your wallet before you confirm. Send from a wallet, not from an exchange, if you can.
