DeFi, explained from first principles

The internals behind every DeFi decision you'll make.

Plain-English walkthroughs of 50+ protocols, free calculators built on the real smart-contract formulas, and side-by-side comparisons — so you can size a position before you commit capital.

What you'll learn here

DeFi moves fast, and the gap between a protocol's marketing site and its on-chain reality is where capital tends to get lost. We read the smart contracts so you don't have to. Every walkthrough starts with the invariant a protocol enforces, the assumptions baked into its math, and the edge cases that trigger liquidations, slashings, or peg breaks in the wild.

You'll find the mechanics needed before clicking Confirm: how an AMM prices a swap when depth thins, what a health factor actually measures, why a lending pool can be drained by a flash loan, and when a stablecoin's backing stops being liquid. Our free calculators run the same formulas protocols execute on-chain, so the numbers here match what the contract will give you when you transact — no rounding, no simplified approximations, no hidden fee schedules.

How we build content

Each hub page starts from the protocol's own documentation, audits, and deployed contract source, then cross-checks governance forums and post-mortems for the mechanics that changed after launch. We verify every formula against the bytecode before it ships, date each page, and revisit whenever a protocol upgrades, a fork launches, or an exploit reveals something the docs glossed over. No paid placements, no tokens to shill — if something here is wrong, tell us and corrections go live the same day.
