This project is an attempt at the Foundry Fund Me lesson from Patrick Collins' course on Solidity, Blockchain Development and Smart Contracts, accessed at the youtube link below: https://www.youtube.com/watch?v=sas02qSFZ74

Getting Started Requirements git foundry

Usage Deploy forge script script/DeployFundMe.s.sol

Testing We use unit and forked tests in this repo forge test Test covergage forge coverage

Deployment Set up environment variables in your .env filr including: SEPLOLIA_RPC_URL PRIVATE_KEY (don't use an address with real funds) ETHERSCAN_API_KEY if you want to verify your contract Deploy: forge script script/DeployFundMe.s.sol --rpc-url $SEPOLIA_RPC_URL --private-key $PRIVATE_KEY --broadcast --verify --etherscan-api-key $ETHERSCAN_API_KEY

Scripts 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/Interactions.s.sol --rpc-url sepolia --private-key $PRIVATE_KEY --broadcast

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

Estimate gas You can estimate how much gas things cost by running: forge snapshot And you'll see an output file called .gas-snapshot

Thank You!
