VIP-391 Multichain Governance - Permissions on Ethereum, Arbitrum one and

opBNB

Summary

If passed, following the Community proposal “Venus Upgrade - Omnichain Money Markets” and the associated snapshot, this VIP will perform the following actions:

- Authorise timelock contracts (Governance) on Ethereum, Arbitrum one and opBNB to execute the same privilege functions they can execute on BNB Chain
- Revoke permissions for the Guardian wallets, to execute the privilege functions that will be authorised for the timelock contracts (Governance) in the previous step
- Transfer 5 BNB from the Venus Treasury on BNB to the Normal Timelock contract, to fund the cross-chain messages

After executing this VIP, no more Guardian transactions will be needed to execute most of the privilege commands on Ethereum, Arbitrum one and opBNB (Guardian will be only required for contract upgrades in those networks, and that will change soon too).

Details

This VIP will update the following number of permissions:

- Ethereum: grant 214 authorizations to Governance and revoke 67 authorizations for the Guardian wallet
- Arbitrum one: grant 190 authorizations to Governance and revoke 52 authorizations for the Guardian wallet
- opBNB: grant 140 authorizations to Governance and revoke 35 authorizations for the Guardian wallet

The numbers of permissions granted and revoked are different because there are different contracts deployed to each network (for example, on Ethereum there are more markets and therefore more contracts).

To apply these changes cross-chain, this VIP uses a new contract (ACMCommandsAggregator). Changes (grants and revokes) are pre-loaded in the ACMCommandsAggregator contracts and the VIP on BNB Chain only sends a message cross-chain to execute specific batches of changes. This reduces the payload sent cross-chain and therefore the gas cost of the VIP execution.
