Deploy a Contract to L2

You can deploy smart contracts to your L2 using rex, a simple CLI tool for interacting with Ethereum-compatible networks.

1. Generate the Contract Bytecode

First, compile your Solidity contract to get the deployment bytecode. You can use solc for this:

solc --bin MyContract.sol -o out/

The bytecode will be in out/MyContract.bin

2. Deploy with rex

Use the following command to deploy your contract:

rex deploy --rpc-url http://localhost:1729 <BYTECODE> 0 <PRIVATE_KEY>

• Replace <BYTECODE> with the hex string from your compiled contract (e.g., contents of MyContract.bin)
• Replace <PRIVATE_KEY> with your wallet's private key. It must have funds in L2
• Adjust the --rpc-url if your L2 node is running elsewhere

For more details and advanced usage, see the rex repository.
