# wstETH on Optimism: deployment artifacts and log ## Cross-chain governance executor 1) For the governance representation, the token and the bridge admin has been set to the Lido DAO agent contract as a final result of deployment The governance executor has been deployed from the following repo: https://github.com/lidofinance/governance-crosschain-bridges/tree/master, the contracts correspond to `master` branch. 2) Deployment instructions: https://github.com/lidofinance/governance-crosschain-bridges#deploying-the-optimismbridgeexecutor, deployment script: https://github.com/lidofinance/governance-crosschain-bridges/blob/master/deploy/gov-bridge-optimism.ts ## Cross-chain governance executor actions log on OP ### Mainnet Deployment (01.08.22) -

[x] Notify dev teams that bridge is enabled #### If Something Goes Wrong - If the test failed - figure out the reason of the failure, and fix it if possible on deployed setup. If it’s not possible, reach out Optimism team, and a biz dev team that the launch must be postponed. Fix the problem and schedule a new release date. --- ## Notes and remarks - Mind some changes should be made in scripts for other OP-stack compatible networks (e.g., `chainId` retrieving: https://github.com/lidofinance/lido-l2/blob/471993c23f3f8c378b9ef4598e703381e9462189/utils/network.ts#L118) - `LDO` is bridged as a default token with the default OP bridge - `stETH` can't be bridged from the get-go because of rebasable mechanics that doesn't propagate cross-bridges (the Lido on Ethereum core protocol doesn't support this yet)
