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.

Proveably Random Raffle Contracts

About

This code is to create a proveably random smart contract lottery

What we want it to do?

1. Users can enter by paying a ticket
   1. The ticket fees are going to the winner during the draw
2. After X period of time the contract will automatically draw a winner
   1. And this will be done progamatically
3. Using Chainlink VRF and Chainlink Automation
   1. Chainlink VRF -> Randomness
   2. Chainlink Automation -> Time Based Trigger
