Uniswap has emerged as a cornerstone of the decentralized finance (DeFi) revolution, offering a trustless, permissionless, and non-custodial platform for trading ERC-20 tokens. This guide explores its mechanics, features, and practical usage.
What Is Uniswap?
Uniswap is a decentralized exchange (DEX) built on Ethereum that enables peer-to-contract token swaps via automated liquidity pools. Unlike centralized exchanges (CEXs) like Binance, Uniswap operates without intermediaries, prioritizing:
- Censorship resistance: No entity can block transactions.
- Self-custody: Users retain control of their private keys.
- Transparency: All transactions are recorded on-chain.
As of recent data, Uniswap boasts a Total Value Locked (TVL) exceeding $3 billion, underscoring its dominance in DeFi.
How Uniswap Works
Automated Market Maker (AMM) Model
Uniswap replaces traditional order books with liquidity pools—crowdsourced reserves of token pairs (e.g., ETH/USDC). Swaps execute via smart contracts using the formula: x * y = k
Where x and y are pool reserves, ensuring prices adjust algorithmically.
Liquidity Providers (LPs)
LPs deposit equal values of two tokens into a pool, earning 0.3% fees from trades. In return, they receive LP tokens representing their share.
