Hayden Adams is the founder of Uniswap, the largest decentralized exchange (DEX) and the protocol that pioneered the automated market maker (AMM) model.
Background
Adams was a mechanical engineer at Siemens before being laid off in 2017. Inspired by a post by Vitalik Buterin about on-chain automated market makers, he taught himself Solidity and Ethereum development and built the first version of Uniswap.
Uniswap
Uniswap V1 launched on the Ethereum mainnet in November 2018. Instead of traditional order books, Uniswap uses liquidity pools and a constant product formula (x * y = k) to enable permissionless token swaps. Anyone can provide liquidity and earn fees, and anyone can create a trading pair for any ERC-20 token without permission.
Uniswap V2 (May 2020) and V3 (May 2021) introduced significant improvements, with V3’s concentrated liquidity allowing liquidity providers to allocate capital within specific price ranges for greater efficiency. Uniswap V4 (2024) introduced hooks — customizable plugins that allow developers to add features to liquidity pools.
Uniswap has consistently been the highest-volume DEX, processing hundreds of billions of dollars in cumulative trading volume. The protocol has been deployed across multiple chains including Ethereum, Polygon, Arbitrum, Optimism, and Base.
UNI Token
In September 2020, Uniswap launched the UNI governance token via one of the most notable airdrops in crypto history, distributing 400 UNI to every address that had previously used the protocol.
Uniswap Labs
Adams leads Uniswap Labs, the primary development company behind the protocol. The company has raised over $175 million in venture funding.
