[Discussion] Adopting ICS-029 IBC Fee Payment #121

Open dongsam opened 4 months ago

Context:

Canto v7 currently uses IBC v3.x
Upgrading to SDK v0.50 and ibc-go v8 is in progress https://github.com/b-harvest/Canto/pull/53
The introduction of ICS-029 Fee Payment from IBC v4 is now a possibility, requiring a decision for adoption.
Considering ICS-029 for decentralized, publicly-funded support to maintain sustainable and stable relayer operations.

Suggestions:

Adopting ICS-029 involves adding a fee module, module account, and processing via middleware, increasing complexity and potential security risks.
Given that this feature is not yet externally vetted or guaranteed for stability, it's advisable to prioritize the v0.50 upgrade first. ICS-029 can be considered for future adoption after ensuring its stability and necessity.

Action Items:

If immediate adoption is deemed unnecessary, remove the fee module from the ongoing v0.50 bump PR.
If future adoption is required, proceed with code validation and risk assessment for the fee module and middleware logic before introducing it in a subsequent upgrade.
