What is a refund address — and why it’s required

A refund address is the wallet your funds return to if a swap can't be completed — for example if a route becomes temporarily unavailable, or your deposit arrives below the required amount.

Why it matters

Crypto swaps are not always instant or guaranteed end-to-end. A route depends on liquidity and on your deposit arriving as expected. If something goes wrong after you've deposited but before the swap settles, the funds need somewhere safe to go. That's the refund address.

Why cross-chain swaps require one

When you swap across networks — say BTC on Bitcoin to USDT on Tron — your recipient address is on the destination network (Tron). A refund, however, has to happen on the origin network (Bitcoin), because that's where your deposit lives. The recipient address can't receive a Bitcoin refund, so a separate refund address on the origin network is required.

For same-network swaps, the recipient address is already on the right network, so a refund address is optional (it can default to your recipient).

What to use

Use a wallet you control on the origin network — ideally the same wallet you'll send the deposit from. Never use an address you don't own, and never use an exchange deposit address that can't handle unexpected refunds.

On CryptoRoute, the refund field is shown directly whenever a route is cross-chain, with the correct network labelled, so there's no guesswork.
