This demo deploys a simple ERC20Mintable to the Scroll zkEVM Alpha testnet, and then mints and transfers some tokens. It uses the Hardhat development framework.

1. npm install
2. Copy .env.example to .env and populate PRIVATE_KEY with your Ethereum private key. Leave the SCROLL_TESTNET_URL

You will need to go to the L1 faucet, request some TSETH and then bridge that to your address on L2: https://prealpha.scroll.io/faucet/

There is an ERC20Mintable.sol in contracts/. This is a simple ERC20 with an unprotected mint() function - do not use it in production.

We will deploy this contract to Scroll, before then minting some tokens to our deploy address and lastly transferring some of those tokens to another user. The logic is contained in the deploy/index.ts script:

1. Compile the contract, run npm run compile
2. Run the deploy script, which will also mint and transfer tokens: npm run deploy

The deploy script will print out the various transaction hashes involved, which can then be looked up on the Scroll L2 block explorer: https://l2scan.scroll.io/
