How long does a failed swap refund usually take to arrive

07 September 2026

A failed swap refund typically arrives within a few minutes to a few hours, but it can take up to 48 hours in rare cases. The actual timing depends on the specific reason the swap failed and the blockchain network conditions at the moment the refund is processed.

When a swap does not complete, the system must first detect the failure. Most swaps fail for one of these reasons: the deposit amount was too low after fees, the deposit arrived after the rate timer expired, or the user sent funds to the wrong address or chain. Once the system identifies the failure, it initiates a refund. For simple failures, like an underpayment, the refund is often automatic and can appear in your wallet within 10 to 30 minutes. The system checks the deposit, calculates what is recoverable (usually the full deposit minus any network fees already spent), and sends it back to the address you sent from.

Network congestion is the most common source of delay. If the blockchain you deposited on is busy, the refund transaction itself may wait in the mempool for confirmation. On Ethereum or similar chains during a gas spike, a refund can take several hours. The refund transaction pays a standard fee, not a premium one, so it does not jump the queue. If the network is clear, the refund confirms quickly.

A more complex failure, such as a deposit to the wrong chain or an address mismatch, often requires manual review. The system cannot automatically return funds if it cannot identify the correct return path. In those cases, a human operator must inspect the transaction logs, verify ownership, and manually construct the refund. This process can take anywhere from a few hours to the full 48-hour window. The site's support team handles these cases in the order they arrive, and they will not process a refund until they are certain the funds are not lost to a scam or a misrouted transaction.

There is also a scenario where the refund itself fails. If you provided an invalid return address, or if the return address is a contract that cannot receive the token type, the refund transaction will bounce. The system will then hold the funds, and you will need to contact support to provide a corrected address. That adds another 24 to 48 hours.

It is important to understand what a failed swap leaves behind. You can read the hub page "What a failed swap leaves behind and how to recover it" for a full breakdown of what funds are actually recoverable and what is permanently lost. Not every failed swap results in a full refund. Network fees spent on the deposit transaction are gone. So are any fees the system paid to attempt the swap before it detected the failure. The refund is the deposit amount minus those sunk costs.

In summary, most refunds arrive within an hour. If you have not seen anything after 48 hours, the refund likely requires manual intervention, and you should open a support ticket with the transaction ID and the address you deposited from. Do not send a second deposit to the same address while waiting; that will create a separate problem covered in the sibling page about duplicate deposits.
