In this repository you'll find 4 scripts we built in the alchemy university discord.
You'll need to compile them using solc (I like using solc-select). Once you have solc installed, run:
solc --optimize --combined-json abi,bin contracts/Game.sol > artifacts/Game.json
Create a top-level .env file, you can use the .sample.env and rename it to .env, filling in both the API_URL and the PRIVATE_KEY. The private key you can use any random 32 byte value. In a node file, or terminal thats as simple as logging out:
require('crypto').randomBytes(32).toString('hex');
For your API_URL you'll want to go to the alchemy dashboard and grab an API_URL from one of your apps. In these scripts we've set them up to target Arbitrum Sepolia so you'll want to setup an arbitrum sepolia app unless you want to change the target chain. Be sure to put the full API URL in here.
Next, you'll want to run the scripts. You can do so by installing the dependencies npm i and then using ts-node for the scripts:
npx ts-node src/1-balance.ts
