Foundry

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Foundry consists of:

• Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
• Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
• Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
• Chisel: Fast, utilitarian, and verbose solidity REPL.

ENV VARS

$RPC_URL $CONTRACT_ADDRESS = http://127.0.0.1:8545 (Anvil - localnet)
$CONTRACT = deployed contract address
$OWNER = deployer
$PRIVATE_KEY = owner private key

To create the contract:

forge create NFT --rpc-url=$RPC_URL --private-key=$PRIVATE_KEY --constructor-args "MyNFT" "MNFT"

Anvil - Localnet

Contract address 0x5fbdb2315678afecb367f032d93f642f64180aa3 Deployer (OWNER) 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266

To Mint NTF using already deployed contract:

cast send --rpc-url=$RPC_URL $CONTRACT_ADDRESS  "mintTo(address)" --private-key=$PRIVATE_KEY

cast call --rpc-url=$RPC_URL --private-key=$PRIVATE_KEY $CONTRACT_ADDRESS "ownerOf(uint256)" 1
