A failed swap can be frustrating, especially when you expect a transaction to finish in seconds. But understanding what happens during a swap makes it easier to identify the problem and avoid repeating the same mistake.
Here is a practical guide to troubleshooting swaps on TON.
Step 1: Check the transaction status
Start by checking your wallet and the relevant transaction details. Determine whether the transaction is pending, failed, or completed. Avoid submitting the same swap repeatedly before understanding what happened.
Step 2: Check your available balance
A swap requires more than the amount you want to exchange. You may also need TON to cover network fees. If your wallet balance is too low, the transaction might not proceed as expected.
Always leave enough TON available for fees rather than spending your entire balance on the swap.
Step 3: Review the quote and minimum received
Token prices can change while a transaction is being prepared or processed. Check the quoted output, minimum received, and slippage settings before confirming.
If the expected output changes significantly, pause and review the trade instead of approving it automatically.
Step 4: Understand liquidity and routing
A token with limited liquidity can be harder to swap at the expected price. On TON, STON.fi uses Omniston to find routes across connected liquidity sources. However, available routes and execution outcomes can vary.
Compare the available quote and review the transaction details before proceeding.
Step 5: Verify before trying again
Confirm that you are using the correct token address and the official application. Never share your wallet recovery phrase with someone offering to fix a failed transaction.
If the issue continues, consult the project's official support resources and provide relevant transaction details without exposing sensitive wallet information.
The takeaway
Troubleshooting starts with checking the transaction, balance, quote, and token details in that order. A failed swap does not always mean your funds are lost, but the actual transaction status matters.
