About The Project

⊛ Users can stake their ETH in the vault (Constant APR 10%)

⊛ User gets rewarded in devUSDC which is an Erc20 token

⊛ We assume that devUSDC is always worth $1

⊛ When a user stakes ETH: all of that ETH will be put as collateral in Compound (v2).

⊛ When a user wants to Withdraw their ETH, the vault will take out the ETH the user staked (without the yields) from Compound and will give it back to the user with the devUSDC rewards

⊛ Minimum amount to stake is 5 ETH

⊛ To get the price of ETH you will need to use a price oracle from chainlink
