The mev-commit chain uses the native ETH tokens that need to be bridged from L1. We use a very basic lock and mint bridge. There is a user CLI application which can be downloaded from the releases page. The bridge will subtract a static finalizationFee from the bridged amount on the destination chain. For now this is a nominal 1 wei. The fee will be increased soon.

In order to bridge funds, users need to have an account which is funded with Holesky ETH for testnet.
Users can also use a keystore file instead of using the private key.
Currently the CLI uses the default contract addresses for testnet and the default RPC endpoints. Users can use separate RPC URLs using the respective options.

To check other options available in the user CLI, users can use the -h option

The current bridge waits for L1 finalization before moving funds in either direction. L1 finalization takes time (~15mins). Users will have to wait for atleast 15 mins before getting confirmation from the application.
