Introduction to Uniswap: The Decentralized Exchange Pioneer
Uniswap stands as the leading decentralized exchange (DEX) built on the Ethereum blockchain, revolutionizing crypto trading through its Automated Market Maker (AMM) model. Unlike traditional centralized exchanges (CEXs), Uniswap enables peer-to-peer trading without intermediaries, offering:
- Non-custodial control (users retain ownership of their assets)
- Permissionless token listings (any ERC-20 token can be traded)
- Liquidity pool-based trading (eliminating order books)
How Uniswap Works: The AMM Revolution
At its core, Uniswap replaces conventional order books with liquidity pools—smart contracts holding pairs of tokens (e.g., ETH/DAI). These pools are funded by Liquidity Providers (LPs) who earn fees from trades. Key mechanics include:
Constant Product Formula (
x * y = k):- Automatically adjusts token prices based on pool reserves
- Ensures continuous liquidity regardless of trade volume
Swap Process:
- Traders exchange one token for another directly with the pool
- Fees (typically 0.3% in V2) are distributed to LPs
