Uniswap v1 popularized pooled on-chain token exchange

Uniswap v1 introduced a simple automated market-maker model in which traders exchanged tokens against liquidity pools governed by smart contracts.

Event / milestone year: 2018First published

The pool design let anyone provide liquidity without placing individual limit orders on a traditional order book.

Its simplicity became a template for a wave of permissionless decentralized exchanges and new liquidity strategies.

Pool trading changes the source of execution risk; slippage, impermanent loss and contract risk still matter to users.
