Uniswap is an Ethereum-based decentralized cryptocurrency exchange (DEX) or a smart contract protocol that allows anyone to swap ERC20 tokens. As the largest DEX globally, Uniswap boasts over $4.3 billion in locked liquidity**, **~$1 billion in daily volume, and $100+ billion in total trading volume since its 2018 launch.
Founded by former Siemens engineer Hayden Adams, Uniswap was inspired by Ethereum founder Vitalik Buterin’s 2016 Reddit post. The project received a $100,000 Ethereum Foundation grant and backing from top VCs like Andreessen Horowitz (a16z).
How Uniswap Works: Centralized vs Decentralized Exchanges
Users choosing a cryptocurrency exchange face two options:
Centralized Exchanges (CEXs)
- Require KYC checks and custody user funds.
- Use order books and market makers for liquidity.
Decentralized Exchanges (DEXs)
- Non-custodial, no KYC.
- Utilize Automated Market Makers (AMMs) for peer-to-contract trading.
Uniswap’s AMMs rely on liquidity pools and the formula X × Y = K to determine token prices algorithmically. For example, swapping ETH for RCX in a pool with 10 ETH and 500 RCX (K=5000) would yield 45.46 RCX for 1 ETH.

Uniswap Governance: The UNI Token
Launched in September 2020, the UNI token decentralizes governance, allowing holders to vote on protocol upgrades and manage the community treasury. Initially airdropped to early users, UNI now trades on major exchanges like Coinbase and OKEx.
Challenges and Future Outlook
While Uniswap dominates the DEX market, high Ethereum gas fees (often $25–$100 per transaction) limit small-scale trading. The anticipated Ethereum 2.0 upgrade aims to resolve scalability issues.
