Automated Market Maker

A decentralized exchange mechanism that prices assets using a liquidity pool and mathematical formula instead of a traditional order book.

Definition

A decentralized exchange mechanism that prices assets using a liquidity pool and mathematical formula instead of a traditional order book.

Why it matters

DeFi concepts explain blockchain-based markets, lending, trading, liquidity, and financial automation.

How it works

The protocol creates a smart contract containing two or more assets. When a user deposits or swaps, the contract recalculates the price using a mathematical model. This process ensures the pool always has assets available for traders at a price that reflects the broader market.

Real-world example

Curve Finance, which uses an optimized algorithm for stablecoin swaps to minimize price slippage.

Advantages
