Just working through some basic workflows.

Foundry Counter Example

Just a simple project for me to practice the basic workflows of Foundry development.

Manual Testing with Anvil

1. Start an Anvil instance (on another terminal) by running anvil. You should get a bunch of public keys and private keys as well as the text "Listening on 127.0.0.1:8545".

2. Make a .env file at project root and place one of Anvil's provided private keys (e.g.PRIVATE_KEY=0x1234...).

3. Run the following to deploy:

   forge script script/Counter.s.sol --broadcast --rpc-url http://localhost:8545

4. (optional) Check that the contract is there by doing a cast call:

   cast call <contract_deployed_address> "number()(uint256)" --rpc-url http://localhost:8545

5. (optional) Send a transaction to the contract by doing a cast send:

   cast send <contract_deployed_address> "increment()" --rpc-url http://localhost:8545 --private-key <private_key_from_anvil>
