The mev-commit chain utilizes advanced bridging mechanisms to ensure a secure and efficient transfer of assets between the Ethereum mainnet (L1) and the mev-commit chain. Below is the process and a breakdown.We envision mev-commit to eventually integrate a multitude of bridges to other chains, using multiple tech stacks
(think wormhole, layerzero, etc.). In the meantime Primev has implemented its own lock/mint bridging protocol as described below.See implementation.
Native ether on the mev-commit chain maintains a 1:1 peg with ether on L1. The only way to mint ether on the mev-commit chain is to lock equivalent ether in a bridge contract on L1. Ether can be burned on the mev-commit chain’s bridge contract to release equivalent ether from the L1 bridge contract.Ether that is used as gas on the mev-commit chain will accumulate in a treasury contract on L1.
There are inherent security assumptions in bridging ether to the mev-commit chain. While these are similar to other bridge trust assumptions, we’ve listed them below:
Selective Bridging: Only bridges originating from Ethereum L1 should be allowed to mint native ether on the mev-commit chain. This is to prevent the impact of compromised states on other chains affecting the mev-commit chain.
