Automated market makers
AMMs like Uniswap replace order books with liquidity pools. Prices are set by a formula based on the ratio of assets in the pool.
This lets any token trade 24/7 without a market maker.
Lending markets
Protocols like Aave and Compound let users supply assets to earn interest and borrow against collateral. Rates float with utilisation.
All loans are over-collateralised — no credit check required.
Oracles
Smart contracts need real-world data (prices, weather, sports results). Oracle networks like Chainlink deliver signed data on-chain.
Oracle failures are a common attack vector — many DeFi hacks trace back to price-feed manipulation.
Yield farming
Depositing capital in DeFi and earning a combination of trading fees, interest and token incentives.
Real returns require netting out impermanent loss, gas costs and token emission decay.
Risks
Smart-contract bugs, oracle manipulation, admin-key misuse, and stablecoin de-pegs are the biggest categories of loss in DeFi.
Only interact with audited protocols, and never allocate more than you can afford to lose.
