Local Testing

To setup a local environment, have two terminals open, both should cd to this localhost directory.

In one terminal, run make node and after that's done, run make deploy in the second terminal.

Once this setup is done, you can cd into your specific task directory in the second terminal and do any additional testing there (keep the node running in the first terminal).

Details

make node runs a node using the Foundry tool anvil. It additionally takes in a genesis file which adds the Gnosis Safe contracts and Multicall3 as predeploys. If you want any additional contracts to be deployed by default locally, they can be added to setup/genesis.json.

make deploy does a few things:

1. Deploy the L1 Base contracts to your local environment
2. Setup a Safe, which is a 2 of 3 multisig containing the first three default localhost accounts provided by Foundry as signers: 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266, 0x70997970C51812dc3A010C7d01b50e0d17dc79C8, and 0x3C44CdDdB6a900fa2b585dd299e03d12FA4293BC. The address of the Safe is 0x41715dd88d95c3c80248f19dace21015346069b8.
3. Transfer ownership of L1 contracts to this Safe.
4. Transfer ownership of SystemConfigOwner to this Safe.

You may run these steps individually if you'd like to not do all of them.
