Introduction to Uniswap
Uniswap is a decentralized finance (DeFi) protocol designed for cryptocurrency token swaps. It operates on the Ethereum blockchain using smart contracts to enable automated trading between tokens. As of October 2020, Uniswap ranks as the largest decentralized exchange (DEX) by daily trading volume and the fourth-largest cryptocurrency exchange overall.
Key Features
- Decentralized Trading: Eliminates intermediaries by relying on blockchain technology.
- Automated Market Maker (AMM): Uses liquidity pools instead of order books.
- Native Token (UNI): Governance token distributed via a 2020 airdrop.
Core Components of Uniswap
1. Smart Contracts
Built with Solidity, Uniswap’s contracts facilitate trustless trading. Key versions:
- Uniswap V1: Basic token swaps.
- Uniswap V2: Introduced ERC-20 pairs and price oracles.
- Uniswap V3: Added concentrated liquidity and tiered fees.
2. Liquidity Pools
Users contribute tokens to pools, earning fees from trades. Example pairs:
- ETH/USDC
- DAI/WBTC
3. UNI Token
- Total Supply: 1 billion UNI.
- Use Cases: Governance voting and protocol upgrades.

Step-by-Step Process
- User Initiates Swap: Requests a token trade (e.g., ETH to DAI).
- Smart Contract Execution: Validates the trade via liquidity pools.
- Fee Distribution: 0.3% fee split among liquidity providers.
