Recently, I discovered a new way to play—specifically for those transactions that get stuck and cannot be canceled when blocks are produced in regular fee Mining Pools like via pool, I made some upgrades.

More mining pool nodes that support normal rates have now been integrated. You can find corresponding pools to handle cancellation requests in different rate ranges, and the success rate has indeed increased in practice. The awkward situation where you clearly provided enough gas but couldn't cancel the order has basically been avoided.
