op-enclave

op-enclave

op-enclave is a relatively small modification to the op-stack that proves state transitions in a AWS Nitro Enclave, and submits the resulting state roots to the L1 chain. This removes the need for the 7-day challenge period, and allows for immediate withdrawals.

Running a testnet

1. Deploy the Nitro certificate manager using make deploy-cert-manager:

IMPL_SALT=0 DEPLOY_PRIVATE_KEY=<privatekey> RPC_URL=https://sepolia.base.org make deploy-cert-manager

1. Deploy the system contracts using make deploy:

IMPL_SALT=0 DEPLOY_PRIVATE_KEY=<privatekey> DEPLOY_CONFIG_PATH=deploy-config/example.json RPC_URL=https://sepolia.base.org make deploy

1. Generate a testnet genesis block and deploy the proxy contracts for a new chain using make testnet:

DEPLOY_PRIVATE_KEY=<privatekey> L1_URL=https://sepolia.base.org make testnet

1. Copy testnet/.env.example to testnet/.env and fill in the environment variables, in particular the # per deploy section at the top.

2. Run the testnet:

docker-compose -f testnet/docker-compose.yml up
