Deploy:

forge script scripts/DeployFundMe.s.sol

forge test

or

// Only run test functions matching the specified regex pattern.
forge test --match-test <testFunctionName>

or

forge test --fork-url $SEPOLIA_RPC_URL

1. Setup environment variables

You'll want to set your SEPOLIA_RPC_URL and PRIVATE_KEY as environment variables. You can add them to a .env file, similar to what you see in .env.example. Optionally, add your ETHERSCAN_API_KEY if you want to verify your contract on Etherscan.

2. Deploy

forge script script/DeployFundMe.s.sol --rpc-url $SEPOLIA_RPC_URL --private-key $PRIVATE_KEY --broadcast --verify --etherscan-api-key $ETHERSCAN_API_KEY

After deploying to a testnet or local net, you can run the scripts.

Using cast deployed locally example:

cast send <FUNDME_CONTRACT_ADDRESS> "fund()" --value 0.1ether --private-key <PRIVATE_KEY>

or

forge script script/FundFundMe.s.sol --rpc-url sepolia  --private-key $PRIVATE_KEY  --broadcast

cast send <FUNDME_CONTRACT_ADDRESS> "withdraw()"  --private-key <PRIVATE_KEY>

You can estimate how much gas things cost by running:

forge snapshot

And you'll see an output file called .gas-snapshot

To run code formatting:

forge fmt
