Unofficial guide on deploying a custom Optimism rollup on Kovan

⚠️ Notice: Guide updated April 2021. Check out the Optimism discord for additional help and support.
Clone optimism contracts:
git clone git@github.com:ethereum-optimism/optimism.git
cd optimism/packages/contracts/
Build optimism contracts:
yarn
yarn build:kovan
Deploy optimism contracts to kovan (replace YOUR_PRIVATE_KEY and L1_NODE_WEB3_URL to your own):
DEPLOYER_PRIVATE_KEY=YOUR_PRIVATE_KEY \
SEQUENCER_PRIVATE_KEY=YOUR_PRIVATE_KEY \
L1_NODE_WEB3_URL=https://kovan.infura.io/v3/PROJECT_ID \
WAIT_FOR_RECEIPTS=true \
WHITELIST_ALLOW_ARBITRARY_CONTRACT_DEPLOYMENT=true \
CHAIN_ID=420 \
RELAYER_PRIVATE_KEY=YOUR_PRIVATE_KEY \
MAX_TRANSACTION_GAS_LIMIT=9000000 \
MIN_TRANSACTION_GAS_LIMIT=0 \
FRAUD_PROOF_WINDOW_SECONDS=604800 \
yarn deploy
The deployment script will write a JSON file to dist/dumps/addresses.json with the contract addresses (your addresses will be different):
