Contract Deployment & Verification Demo

This project demonstrates how to use hardhat or foundry to deploy a contract in a rollup network. This project contains a simple contract that will lock a certain amount of Ether in the deployed contract for a specified amount of time.

Deploy with Hardhat

1. If you haven't already, install nodejs and yarn.
2. Run yarn install to install dependencies.
3. Create a .env file following the example .env.example in the root directory. Change PRIVATE_KEY to your own account private key in the .env.
4. Run yarn compile to compile the contract.
5. Run yarn deploy:merlinTestnet to deploy the contract on the Scroll Alpha Testnet.
6. Run yarn test for hardhat tests.

Verify

npx hardhat verify --network merlinTestnet {contract-address} {contract-args}
