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.
This code is to create a proveably random smart contract lottery.
- Users can enter by paying for a ticket.
- The ticket fees are going to go to the winner during the draw.
- After X period of time, the lottery will automatically draw a winner.
- And this will be done programatically.
- Using Chainlink VRF & Chainlink Automation
- Chainlink VRF -> Randomness
- Chainlink Automation -> Time based trigger
- Write some deploy scripts
- Write our tests
- Work on a local chain
- Forked testnet
- Forked Mainnet
