Cancellation of Pending Transaction

[xBalbinus]

Description:
Is it possible to cancel a pending transaction, eg a InvokeContract call?

Motivation: Currently, there's one message on https://filfox.info/en/address/f410fko6732us66tav34cekesnubipaayvs2o4pv46mi that has been pending for 8h. This is due to the rise in gas prices (https://filfox.info/en/stats/gas). We want to recover our system and get calls to work again. Our hope is that we can cancel such a transaction, and resubmit it with more gas. Would something like this help?

• Ribasushi slack message explaining how to cancel a message stuck in the mpool.
• There is a lotus doc explaining how to increase gas fee for the pending transaction using Lotus cli.
  @xBalbinus maybe we can write a tutorial on how to cancel or expedite the pending transactions? Usling Lotus CLI or API calls, or event with other tools if possible ?

[xBalbinus]

Yes, we should write some documentation on this. Normally though, both hardhat and foundry innately have capabilities for you to cancel / skip existing transactions, so this might end up even as a P2.

tutorial on how to cancel or expedite the pending transactions

There are 3 paths:

1. This assumes Lotus CLI isn't readily available to general dev. Possible to do via ethers.js, to reconstruct pending transaction with updated gas fee (this is a common fix for evm devs, but filecoin devs might be unfamiliar)
2. For Lotus CLI, there's a docs page for this existing. No action needed.
3. Another solution for txns initialized on metamask - there is a cancel feature.

End result should be a fix on forum and amplified to builders
