Create a .env file with the following entries:

SEPOLIA_RPC_URL=<sepolia_rpc_url>
PRIVATE_KEY=<private_key>
ETHERSCAN_API_KEY=<etherscan_api_key>

Install project dependencies

make install

Deploy the smart contract on Anvil

make anvil
make deploy

Deploy the smart contract on Sepolia

make deploy ARGS="--network sepolia"

The project contains a suite of unit and invariant (fuzz) tests. To run against a local Anvil Ethereum node:

forge test

To run against a forked environment (e.g. a forked Sepolia testnet):

forge test --fork-url <sepolia_rpc_url>
