Deploying a Stablecoin
summary
Walks through building an over-collateralized onchain stablecoin using five contracts: a simplified DEX, a stub oracle, an ERC20 with restricted mint/burn, an engine for collateral/mint/liquidations, and staking plus a rate controller. Uses Scaffold-ETH demo and burner wallets to deposit 10 ETH, mint $11,000 (≈163% collateralization), run bot simulations where raising borrow rate from 0% to 10–20% restores the peg, and shows liquidations and staking mechanics.
