Why this topic matters
An automated market maker, or AMM, calculates prices from assets held in a liquidity pool and a defined formula instead of matching a traditional order book. Traders swap against the pool, while liquidity providers may receive part of the fees.
A practical review order
The asset ratio changes after trades, so a large order can move the price substantially. This price impact or slippage depends on pool depth and trade direction.
Common mistakes to avoid
Liquidity providers earn fees but can experience a different result from simply holding the assets when relative prices change. Impermanent loss, contract bugs, oracle risk, and administrator powers also matter.
Key takeaway
AMMs do not make trading risk disappear. They distribute different risks among traders and liquidity providers, so understand the formula, fees, pool assets, and withdrawal conditions first.
