Hello PancakeSwap Community,
I am currently facing one specific integration problem with my website where the PancakeSwap swap functionality does not consistently update the transaction status after a user submits a token swap. The swap interface loads correctly on the website, users can connect their wallet, select the tokens, enter an amount, and proceed through the normal transaction confirmation process. The problem occurs after the transaction has been submitted: in some cases, the blockchain transaction appears to have completed successfully, but my website continues displaying the transaction as pending instead of updating the interface to show that the swap has finished. The user can see the transaction in their wallet or blockchain explorer, but the website itself remains stuck on the previous transaction state until the page is refreshed. I am trying to troubleshoot this as one specific transaction-status synchronization problem rather than an issue with the overall swap interface.
The integration is implemented through JavaScript on my website, and the application monitors the transaction after the user confirms it through their wallet. Under normal circumstances, the website submits the transaction, waits for the transaction response, and then updates the interface once the transaction has been mined. This works correctly for many transactions, which confirms that the basic wallet connection and transaction submission logic are functioning. However, with certain transactions, the initial transaction request is successfully returned but the application does not appear to receive or process the final confirmation correctly. The blockchain state shows that the transaction has already been included, yet the website continues waiting as though the transaction has not finished. Because the same code works correctly for other swaps, I am having difficulty determining whether the issue is related to transaction polling, RPC responses, confirmation handling, or the way my application interprets the transaction status.
I have been inspecting the browser developer console and network requests when the problem occurs, and there is no obvious frontend exception that immediately explains why the status remains pending. I have also recorded the transaction hash whenever possible so that I can compare transactions that update correctly with transactions that remain stuck in the website interface. When a transaction succeeds normally, the application receives the expected confirmation and changes the UI accordingly. In the affected cases, the transaction hash exists and the transaction can be located externally, but the corresponding confirmation does not appear to reach the part of my application responsible for changing the status. I am therefore trying to determine whether I should be relying on a particular transaction receipt or confirmation mechanism instead of assuming that the initial wallet response is sufficient for tracking the transaction lifecycle.
The problem is especially noticeable because refreshing the page usually causes the website to recognise the completed transaction or at least stop showing the previous pending state. This makes me think that the blockchain transaction itself is not necessarily the problem and that the issue may be with how the website monitors the transaction while the user remains on the page. I have considered whether temporary RPC delays or a missed response could cause the frontend to stop checking the transaction even though it remains pending from the application’s perspective. I have also checked that the website is using the expected network and contract information for the swap, and I am not intentionally changing the transaction state after submission. My main concern is making the frontend reliably detect the final transaction state without requiring the user to manually refresh the page.
I have started adding additional logging around the transaction lifecycle so I can capture the transaction hash, submission timestamp, polling attempts, returned receipt information, and the point at which the UI changes from pending to completed. I want to compare a successful transaction with one that remains stuck and identify exactly where the two flows diverge. I am particularly interested in knowing whether there is a recommended PancakeSwap or blockchain integration pattern for monitoring transactions after a swap has been submitted, especially when the frontend is running continuously in a browser and may encounter temporary RPC delays. I also want to avoid repeatedly submitting the same transaction simply because the website has not received confirmation, since the original transaction may already have succeeded on-chain. The goal is therefore to make the existing transaction-status handling more reliable rather than introducing another submission mechanism.
I would appreciate guidance from the PancakeSwap community on how to properly diagnose this specific issue where an on-chain swap completes but my website continues showing the transaction as pending until the page is refreshed. In particular, I would like to know what transaction receipt, confirmation, RPC, or frontend event information I should capture to determine whether the problem is occurring during transaction monitoring or during the final UI state update. If there is a recommended approach for reliably detecting a completed swap and handling temporary RPC responses without losing track of the transaction, I would be grateful for advice. My goal is to ensure that once the transaction has actually reached its final on-chain state, my website consistently reflects that state to the user without requiring a manual page refresh. Sorry for long post!
