A mechanism-first walkthrough of decentralized finance that explains how the plumbing actually works, not which farm to chase this week. Each part builds on the previous one, moving from the base primitives (tokens, wallets, gas) through AMMs, lending, stablecoins, and oracles, then up to the real risks — impermanent loss, liquidation cascades, and smart-contract exploits — so readers can evaluate any DeFi protocol on their own terms.
DeFi replaces banks and brokers with public smart contracts. Here is what that actually means, mechanically, and why one change cascades into everything else.

Impermanent loss is the hidden cost of being an AMM liquidity provider. Here's the math, a reference table, and a checklist to decide if the fees are worth it.

Smart contracts are sealed from the outside world by design. Oracles are the signed conduits that pipe prices in — and the single point where DeFi most often breaks.

DeFi's composability lets protocols stack like Lego, but it also means one oracle glitch or depeg can cascade across lending, AMMs, and stablecoins in minutes.
