Transactions could fail or get stuck, according to the documentation:
And there are several options provided:
However, some transactions execution depend on the time or certain condition. For example, some transaction has a deadline, it the deadline is passed, the transaction will be invalid. Or some conditions may be temporary, for example, some certain price difference for some token pair. In this case, the failed transactions will be meaningless to redo, the appropriate method is to cancel the transaction and refund. If no such option is provided, users fund for this transaction would be lock or loss.
The options are approveContractCall(), execute, addGas() and addNativeGas() are available, but no cancel and refund option.
Provide a cancel option if the transaction failed, from the source chain or destination chain, and allow the user to get the gas refund.
