Can I cancel a swap after starting it?

Once you send funds and the network confirms the transaction, a swap cannot be cancelled in the traditional sense — it is already executing. What you can do is wait for completion or, if something looks wrong, contact support with your exchange ID (the identifier shown after you start the swap). If the platform determines the swap cannot be finished, your funds will be returned to the change address. For FloatingRate swaps you can also choose to restart if the rate moves before you send funds.

A typical ChangeNOW swap is a five-step flow: pick the pair, choose FixRate or FloatingRate, enter the receiving address, send your coins, and wait for the exchange to be forwarded to your address. Most swaps complete in 5–30 minutes depending on network congestion, and the exchange status is trackable in real time on the official site.

Two habits prevent the vast majority of swap problems: always set a change (refund) address, and start with a small test transaction when trying an unfamiliar pair. If a swap fails, the change address is where ChangeNOW returns your funds, so leaving it empty or wrong is the most common user error.

Bottom line

Once you send funds and the network confirms the transaction, a swap cannot be cancelled in the traditional sense — it is already executing. For the full picture, see the complete ChangeNOW FAQ covering fees, KYC, limits, refunds, supported coins, and more.
