Optimism and Uniswap plan native ETH transfers between OP Mainnet and Unichain
- —OP Mainnet and Unichain would form the first interoperability set, initially limited to native ETH
- —Message verification moves into the participating chains via OP Stack; a relayer cannot determine validity
- —Upgrades 20 and 21 are preparatory only; activation details need a separate governance proposal
- —General token compatibility and a combined liquidity pool are outside the initial scope
Why it matters: Direct transfers between major L2s would reduce reliance on bridges, but launch hinges on governance approval and coordinated upgrades.
