Deployment

Set private key of the deployer.

export PRIVATE_KEY=<KEY>

Set the arbiscan API key

export ETHERSCAN_API_KEY=<API_KEY>

Run the script to deploy.

npx hardhat --network arbitrum_sepolia run deploy/deploy_zkcenter.ts

The deployment process checks against a JSON file named after the network. During the initial deployment, this JSON file is created. For subsequent runs, the script compares the name2() value of the contract with the corresponding expectedName2 field in the JSON file. If they do not match, a contract upgrade will be triggered. Therefore, when updating a contract, make sure to update both the return value of name2() and the expectedName2 field in the JSON file. This ensures the deployment script can handle the process correctly.

Verify the deployed contract.

npx hardhat verify --network arbitrum_sepolia <CONTRACT ADDRESS>

Update the new address to TaikoL1 if needed.

env PRIVATE_KEY=<OWNER_ADDRESS> npx hardhat --network arbitrum_sepolia run deploy/set_zkcenter_to_taikol1.ts

Set controller.

env CONTROLLER_ADDRESS=<ADDRESS> npx hardhat --network arbitrum_sepolia run deploy/set_zkcenter_controller.ts
