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.

- (Relative Stability) Anchored or Pegged -> $1.00
- Chainlink Price feed.
- Set a function to exchange ETH & BTC -> $$$
- Stability Mechanism (Minting): Algorithmic (Decentralized)
- People only can mint the stablecoin with enough collateral (coded)
- Collateral: Exogenous (Crypto)
- wETH
- wBTC
- calculate health factor function
- set health factor if debt is 0
- Added a bunch of view function
- what are our invariants/properties?
