What happens to a swap if I close the browser tab and come back tomorrow

07 September 2026

The swap will still be there, waiting in exactly the same state you left it. Closing the tab does not cancel, pause, or reset the transaction.

Here is why that works. The swap is not running inside your browser. It is a set of instructions written to the blockchain and tracked by the exchanger's backend servers. Your browser tab is just a window into that server's records. When you close it, the server continues monitoring the chain for your deposit, confirming blocks, and moving funds through the swap pipeline. The exchanger does not know or care whether your tab is open.

The only thing that changes is your ability to see updates. While the tab is closed, you cannot watch the status bar advance. You cannot see a new block get confirmed. But the underlying sequence of contract calls and signature verifications proceeds exactly as if you were staring at it. The exchanger's system polls the network on a schedule, typically every few seconds to a minute depending on the chain. That polling continues regardless of any browser state.

If you open the tab again tomorrow, the page will load the current swap status from the server. You might see that the swap completed hours ago, or that it is still waiting for confirmations on a slow chain. The interface will show the same swap ID, the same deposit address, the same expected output. Nothing resets. Nothing restarts.

There is a subtle point about session tokens and local storage. Some swap interfaces store a temporary identifier in your browser so you can find your recent swaps without needing the swap ID. If you clear your browser cache or use a different device, you will lose that shortcut. But the swap itself remains live on the server. As long as you have the swap ID - typically a long string of letters and numbers - you can always pull up the status from any browser, any device, any continent. Write that ID down somewhere separate from the browser. Relying on cookies alone is a risk that has stranded users.

What can go wrong while you are away? The swap might stall if the network experiences a congestion spike and your deposit transaction had a low gas fee. It might sit in the mempool for hours, unconfirmed, while the exchanger's clock keeps ticking. When you return, you could find that the swap has expired because the quote window lapsed. The exchanger's terms usually state a maximum time a swap can remain open without a confirmed deposit. That window is often measured in hours, not days. If the deposit never confirms within that window, the swap is marked as abandoned. Your funds remain in your wallet; the exchanger never received them. You simply need to try again with a higher gas fee.

If your deposit did confirm but the swap then failed to proceed - for example, because the destination chain had an outage - the funds may be stuck in an intermediate contract. That is a separate problem covered in detail under the hub page "Why your swap is stuck and what to do." That page walks through the specific failure modes and the steps to recover funds from a stranded state. It is the right place to go if you return to a swap that shows "Awaiting" or "Failed" for more than a day.

Closing the tab is safe. The system is designed to tolerate disconnection. Your job is to keep the swap ID and to check back within the expiry window. The exchanger's job is to keep watching the chain. Both can succeed without the tab ever being open.
