When gas prices increase slow or average speed transaction can be pending for a long time. Autotask is great in it will automatically issue new transactions with a higher gas price for the same nonce, but sometimes this is not the desired result. It’d be nice if a user can initiate a cancel transaction to be sent to replace the currently pending transaction.
Got it! Do you imagine doing that from a script that takes care of cleaning up pending txs, or from the site where you see the in-flight txs and can manually cancel them?
I was imaging the second option where a user can cancel in-flight txs manually from the UI.
