Bridge CLI

The mev-commit chain uses native ETH that must be bridged from L1 using our lock and mint bridge. A user CLI application can be downloaded from the releases page.

Or download the 1.0.0 bridge CLI directly from the links below:

• Darwin ARM64
• Darwin x86_64
• Linux ARM64
• Linux x86_64
• Windows x86_64

You can confirm your operating system and architecture by running uname -sm.

On MacOS, a warning may appear about running untrusted software. Try using xattr -d com.apple.quarantine ./user-cli to disable this warning, or feel free to build/use the CLI from source here.

In order to bridge funds, users need to have an account which is funded with mainnet ETH.

❯_ bridge to settlement chain from L1

user-cli bridge-to-settlement \
	--account-key <Private Key of source account> \
	--dest-addr <Address to fund on the mev-commit chain> \
	--amount <Amount in Wei>

user-cli bridge-to-l1 \
	--account-key <Private Key of source account> \
	--dest-addr <Address to fund on the mev-commit chain> \
	--amount <Amount in Wei>

A static fee is charged for bridging from the mev-commit chain to L1, to compensate the relayer for transaction inclusion. This fee is currently set to 0.005 ETH.

Users can also use a keystore file instead of using the private key.

CLI currently uses default contract addresses for mainnet and default mainnet 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

./user-cli bridge-to-settlement -h
NAME:

USAGE:
   mev-commit-bridge-user-cli bridge-to-settlement [command options]

OPTIONS:
   --account-key value               private key of the account to use for signing transactions in hex encoding [$ACCOUNT_KEY]
   --keystore-path value             path to keystore location [$MEV_ORACLE_KEYSTORE_PATH]
   --keystore-password value         use to access keystore [$MEV_ORACLE_KEYSTORE_PASSWORD]
   --amount value                    amount of ether to bridge in wei [$AMOUNT]
   --dest-addr value                 destination address on the mev-commit (settlement) chain [$DEST_ADDR]
   --l1-rpc-url value                URL for L1 RPC [$L1_RPC_URL]
   --settlement-rpc-url value        URL for settlement RPC [$SETTLEMENT_RPC_URL]
   --l1-contract-addr value          address of the L1 gateway contract [$L1_CONTRACT_ADDR]
   --settlement-contract-addr value  address of the settlement gateway contract [$SETTLEMENT_CONTRACT_ADDR]
   --silent                          disable spinner (default: false) [$SILENT]
   --help, -h                        show help

The current bridge waits for finalization. Thus when moving funds from L1 to the settlement chain, users will have to wait for at least 15 mins (L1 finalization time) before getting a confirmation. Conversely, bridging from settlement to L1 chain will be significantly faster (less than 1 second settlement chain finalization time).

After the bridge is successful, the following command can be used to check their mev-commit chain balance

Mainnet

cast balance mev_commit_mainnet_address --rpc-url https://chainrpc.mev-commit.xyz/

Testnet

cast balance mev_commit_testnet_address --rpc-url https://chainrpc.testnet.mev-commit.xyz/
