• Scroll V3 (Stata tokens) - No seatbelt

• Scroll V3 (Price oracle sentinel) - https://github.com/bgd-labs/seatbelt-gov-v3/blob/main/reports/payloads/534352/0x6b6B41c0f8C223715f712BE83ceC3c37bbfDC3fE/3_forge.md

Technical analysis

We have verified that the payload activates the Price oracle sentinel on the Scroll chain.

We have also verified that the payload upgrades the Static a token implementation of all stata tokens on the following chains: Ethereum, Polygon, Avalanche, Optimism, Arbitrum, Metis, Base, Gnosis, BNB, Scroll and that the new implementation fixes the 2 following bugs:

• For reserves without a supplyCap the maxMint function on the static aToken would revert.

• The static-a-token is prone to permit griefing.

The proposal is consistent with the description on the governance forum.
