Uniswap is a decentralized application (dApp) built on the Ethereum blockchain, enabling permissionless trading of ERC-20 tokens. As a decentralized cryptocurrency exchange (DEX), it eliminates intermediaries by leveraging smart contracts—autonomous, immutable code that ensures censorship-resistant, secure, and self-custodied transactions.
History of Uniswap
Launched in 2018 by Hayden Adams, Uniswap has evolved through multiple versions (V1–V3), each enhancing functionality:
- V1: Introduced basic token swaps via liquidity pools.
- V2: Enabled ERC-20/ERC-20 trading pairs.
- V3: Added concentrated liquidity, NFTs, and dynamic fees.
