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.

Our stablecoin is going to be:

1. Relative Stability: Anchored or Pegged to the US Dollar
   1. Chainlink Pricefeed
   2. Function to convert ETH & BTC to USD
2. Stability Mechanism (Minting/Burning): Algorithmicly Decentralized
   1. Users may only mint the stablecoin with enough collateral
3. Collateral: Exogenous (Crypto)
   1. wETH
   2. wBTC

• calculate health factor function
• set health factor if debt is 0
• Addes a bunch of view function

1. What are our invariants/properties?

2. Some proper oracle use

3. Write more test

4. Smart Contract Audit Preparation
