DeFi replaces order books, lenders and brokers with smart contracts that anyone can use from a wallet. This path starts with how Ethereum and its layer-2 networks work, then covers automated market makers, liquidity providing, lending, stablecoins, staking and bridges, and finishes with how to judge the risk and read the data.
Read this first. DeFi has no support desk and no deposit insurance. Smart-contract bugs, oracle failures, bridge hacks, fake front-ends and bad approvals have cost users large sums, and transactions cannot be undone. Yields are variable and often paid in tokens that can lose value. Leveraged and borrowed positions can be liquidated automatically. Rules for using and being taxed on DeFi differ by country. Nothing here is investment advice, and protocols named are examples of a mechanism, not recommendations.
