Introduction to Uniswap
Uniswap is a decentralized cryptocurrency exchange (DEX) that operates on the Ethereum blockchain. Unlike traditional centralized exchanges, Uniswap uses automated smart contracts to facilitate peer-to-peer trading without intermediaries. Founded in 2018 by Hayden Adams, Uniswap has grown to become one of the most influential platforms in the decentralized finance (DeFi) ecosystem.

How Uniswap Works
Automated Market Maker (AMM) Model
Uniswap’s core innovation is its Automated Market Maker (AMM) system, which replaces order books with liquidity pools. These pools are funded by users who deposit pairs of tokens, enabling seamless trading.
- Liquidity Providers (LPs): Users who deposit tokens earn fees from trades.
- Constant Product Formula: Ensures price stability by maintaining a product of token quantities (x * y = k).
Key Features
- Permissionless Listing: Any ERC-20 token can be traded without approval.
- Non-Custodial: Users retain control of their funds via wallet integrations.
- Decentralized Governance: UNI token holders vote on protocol upgrades.
