What Is Uniswap?
Uniswap is a leading decentralized finance (DeFi) protocol and one of the largest decentralized cryptocurrency exchanges (DEX) by trading volume. Built on Ethereum, it enables peer-to-peer token swaps without intermediaries through automated liquidity pools.
Key Features:
- Decentralized Trading: Swap ERC-20 tokens instantly using smart contracts.
- Liquidity Pools: Users provide liquidity and earn fees in return.
- Permissionless Listings: No fees for token listings; any ERC-20 token with a pool can be traded.
UNI Token
UNI is Uniswap’s governance token, launched in 2020 to decentralize decision-making. Holders can:
- Vote on protocol upgrades.
- Fund community initiatives like liquidity mining.
- Trade or stake UNI for investment purposes.

Uniswap’s Founders and History
Uniswap was created in 2018 by Hayden Adams, inspired by Vitalik Buterin’s concept for an on-chain AMM (Automated Market Maker). Adams, a mechanical engineer turned developer, leveraged Ethereum’s smart contracts to solve liquidity challenges in decentralized exchanges.
Key Milestones:
- 2018: Uniswap V1 launch.
- 2020: Uniswap V2 introduced, featuring ERC-20/ERC-20 pools and flash swaps.
- UNI Airdrop: 400 UNI tokens distributed to early users.
How Uniswap Works
Automated Market Maker (AMM)
Uniswap’s AMM algorithm uses the formula x × y = k to determine token prices based on pool liquidity ratios:
- x: Quantity of Token A.
- y: Quantity of Token B.
- k: Constant product maintained by the pool.
Example: Swapping ETH for DAI adjusts the pool’s ETH/DAI ratio, slightly shifting the price to reflect supply/demand.
Liquidity Provider (LP) Incentives
LPs earn:
- Trading Fees: 0.3% per swap (distributed proportionally).
- UNI Rewards: For participating in governance or staking.
