AMM: Automated Market Making
Automated Market Makers use mathematical formulas to price assets and facilitate trading without traditional order books. They're like vending machines for cryptocurrency trading.
An Automated Market Maker (AMM) is a decentralized exchange mechanism that uses mathematical algorithms to price assets and facilitate trading through liquidity pools instead of order books. AMMs enable constant liquidity availability for supported trading pairs.
How AMMs Work
Liquidity pools contain reserves of two or more tokens that traders can swap against using predetermined mathematical formulas.
Pricing algorithms like the constant product formula (x * y = k) automatically adjust prices based on pool ratios and trade sizes.
Liquidity providers deposit tokens into pools and earn fees from trades proportional to their share of total pool liquidity.

Real-World Examples
- Uniswap popularized the constant product AMM model and dominates Ethereum DEX trading
- Curve Finance specializes in stablecoin trading with low-slippage algorithms
- Balancer enables pools with multiple tokens and customizable weight ratios
Why Beginners Should Care
Always available trading since AMMs provide liquidity 24/7 without requiring human market makers.
Earning opportunities through liquidity provision that generates fees from trading activity.
Impermanent loss risks when providing liquidity to volatile trading pairs that can result in losses compared to holding tokens separately.
