Can you cancel a swap after the deposit transaction has been sent

07 September 2026

No, you cannot cancel a swap once the deposit transaction has been sent. The moment your coins leave your wallet, the swap is committed to the sequence of operations that will deliver the output to you.

Here is why. A swap on babybuilder.xyz is not a single action. It is a chain of independent steps: you send a deposit, the exchanger detects that deposit, it locks the rate you accepted, it waits for the required number of block confirmations on that chain, then it sends the output to your destination address. Each step depends on the previous one having completed. There is no pause button, and there is no recall command that works retroactively on a blockchain transaction.

The reason cancellation is impossible has to do with how blockchains treat transactions. Once a transaction is broadcast and included in a block, it is final. The network does not maintain a queue of "pending swaps" that you can edit. The deposit is now a permanent record on that chain. The exchanger's software watches for that specific transaction hash, and when it sees it, it proceeds automatically. There is no human operator sitting in the middle who can be asked to reverse course.

What you can do before sending the deposit is refuse to send it. That is the only real cancellation point. If you have not broadcast the transaction, the swap is still just an accepted quote, and you can walk away. Once the transaction is out of your wallet, the swap will run to completion regardless of whether you change your mind.

A few practical notes. If you made a mistake in the destination address, that error will be permanent. The exchanger will send the output to whatever address you specified, and it cannot be recovered. If you sent the wrong amount, the swap will still process that amount, and you will receive the converted value minus network fees. If the network becomes congested after you send your deposit, the swap will wait for confirmations rather than fail, but waiting is not cancelling. The swap will eventually complete when the chain clears.

There is one edge case worth mentioning. If the deposit transaction never confirms - for example, because you set a fee that is too low and the network is busy - the swap might time out after a long period. In that scenario, the exchanger's system will eventually mark the swap as expired, and the funds may be returned to your original address, minus any fees. But that is not a cancellation. That is a failure of the deposit to register, and it happens only under unusual conditions.

If you are in the middle of a wait and you are worried about what you have sent, the useful thing to do is check the block explorer for your deposit transaction. That will tell you how many confirmations it has. Beyond that, there is nothing to do but wait. The system is deterministic. It will finish when it finishes.

For a fuller picture of what actually determines that waiting time - and what you can usefully do while a swap is running - the hub page that covers this topic is "Why swap times vary and what to do during the wait." It goes into the mechanics of confirmations, network load, and the difference between a quote window and a fixed time. This page only answers the cancellation question, and the answer is no. Send the deposit, and the swap is locked in. Plan accordingly before you broadcast.
