What happens if you send less than the swap amount

Why a deposit arrives short

• Your wallet or exchange took its network fee out of the amount you typed. This is the most common cause, and the shortfall is usually well under 1%.
• The amount was rounded. A swap may ask for 0.00288403 and a wallet may only accept 0.002884.
• The deposit was sent in two payments and only the first has arrived.

What the swap does next

It depends on the route, and the swap page says which of these applies to you.

• A small shortfall: some routes still make the swap and pay out in proportion, so you receive slightly less than quoted.
• A larger shortfall: the swap page shows how much is missing and until when you can send it to the same deposit address.
• A swap that needs the exact amount, such as a fixed-rate swap: the swap is not made and the deposit is returned to your refund address, less the network's fee for sending it back.

How you get your coins back

Open the swap page with your swap ID. When a deposit is being returned, the page shows what was needed, what arrived, the time the return starts and the address it goes to. A return to your refund address is automatic: you do not need to ask anyone.

If the swap was created without a refund address, contact support with your swap ID. You will be asked for an address for the coin you sent.

A returned deposit comes back less the network's fee, so expect slightly less than you sent.

How to avoid it next time

• Send exactly the amount shown, not a rounded one. Use the copy button next to it.
• If your wallet or exchange takes its fee out of what you send, add the fee on top so that the full amount arrives.
• Send one payment, from a wallet you control.
• Where the swap page offers a QR code with the amount, scan that one: your wallet then fills in the exact figure.
