Hey Griff. I can add some color from the Metagov group on this.
To answer your questions, it would be the ENS DAO, not ENS Labs, that would fund the audits.
For preparedness sake, Metagov maintains a budget line item to fund contract audits for any successful proposals that contain contract changes that are in any way relevant to the protocol. At the start of Term 5 we budgeted 90k for audits in 2024. We lowered that estimate down to 40k mid year, mainly because we haven’t needed to audit anything so far in 2024.
If the delegates vote to support this proposal, or any proposal with a contract change, Metagov would use those funds to independently audit any proposed contract changes. This is regardless of any other audits the proposer may or may not perform.
