Uniswap and the Emergence of the Decentralized Exchange

Despite blockchain based cryptoassets trading since 2009, there has been a functional gap between on-chain transactions and trust based centralized exchanges. Uniswap, a decentralized exchange, bridges this gap. Uniswap’s constant product automated market maker enables the trading of blockchain tokens without relying on market makers, bids or asks. This reimagines conventional financial market structure in ways that challenge regulation, and increases market completeness as any size of volume can be traded at any time in a predictable way.
