Beginner's Track, Lending & Stablecoins
summary
Walks through an actual Scaffold-ETH demo that deploys a three-contract system (staking, engine, ERC20) and mints a stablecoin called MyUSD; depositing 10 ETH mints ~$10,000 and shows collateralization targets (example 150% safety ratio) and liquidations. Uses a dummy DEX, omits a live oracle, and runs a 5 bots simulation that reacts when borrow rates move from 0% to 30%, demonstrating price pressure, MyUSD minted mechanics and savings-rate incentives.
