What happens to my swap if the app closes or the screen locks before it confirms

21 September 2026

If the app closes or your screen locks before the swap confirms, your funds are not lost. They will either be returned to your wallet automatically or remain in a pending state that you can resume.

Here is why that is true, and what you need to know.

A swap on wpay.sg is not a single instant event. It has several stages. You send deposit tokens to the exchanger. The exchanger receives them. The exchanger processes the order. The exchanger sends you your swapped tokens. Most failures happen between the deposit and the processing step.

When your phone app closes or the screen locks during that window, the deposit may still arrive at the exchanger. The exchanger does not need your phone to be open. It watches the blockchain for incoming transactions. If your deposit transaction was broadcast before the app closed, the exchanger will see it and process the swap. You will receive your swapped tokens to the destination address you provided.

The risk is not that the money disappears. The risk is that you lose track of the order. If the app closes before you see a confirmation screen, you may not know whether the deposit was sent. You may also not know the exact order ID or destination address if you did not save it.

If your deposit was sent but the app crashed before the swap finished, the exchanger will still complete it. Your swapped tokens will arrive. You can check the status by returning to the swap history on the site after reopening the app. If you cannot find the order, contact support with your wallet address and the approximate time and amount of the deposit.

If the app closed before you even sent the deposit, nothing happened. No funds left your wallet. You can start again.

A more common problem is the screen locking while the deposit transaction is being signed by your mobile wallet. Some mobile wallets require you to confirm the transaction with a biometric or PIN. If your phone locks during that prompt, the transaction is not broadcast. The swap is not initiated. Your tokens are still in your wallet. Unlock your phone and try again.

The most confusing scenario is when the deposit transaction was broadcast but the app closed before you could copy the order ID. In that case, the exchanger will still process the swap. But if something goes wrong later - for example, the exchanger cannot complete the order - you have no reference number. That makes it harder for support to trace. The fix is simple: before you start a swap, write down or screenshot the order ID shown on the swap page. Do that before you send the deposit.

The hub page for this content is "Mobile wallet swap mistakes with carbon credit tokens." That page covers the broader pattern of errors that come from treating a mobile swap like a casual app interaction. If you are making swaps with carbon credit tokens, the stakes are higher because those tokens often have low liquidity or unusual network settings. A locked screen or closed app can turn a small mistake into a lost order.

To summarise: a closed app does not destroy your funds. It only breaks your visibility of the swap. If the deposit was sent, the exchanger will finish the job. If the deposit was not sent, nothing is at risk. The real danger is ignorance of the order status, not the loss of the tokens. So save your order ID before you send, and do not panic if the app disappears.
