Learn more about Uniswap V2 Core

Uniswap V2 Core is a collection of Ethereum smart contracts that implement an automated market maker (AMM) protocol for decentralized token trading. The system uses a constant product formula (x * y = k) to determine exchange rates and maintains liquidity through user-contributed token pairs stored in smart contract pools. The contracts are written in Solidity and include factory contracts for creating new trading pairs, pair contracts for managing individual liquidity pools, and ERC20 token implementations for liquidity provider tokens. The protocol is commonly used for decentralized token swapping, liquidity provision, and as infrastructure for other DeFi applications.

Constant Product AMM

Implements the x * y = k automated market maker formula for price discovery and liquidity management. This mathematical model ensures continuous liquidity availability for token swaps.

Factory Pattern Architecture

Uses a factory contract system to programmatically deploy new trading pair contracts. This allows for permissionless creation of markets for any ERC20 token pair.

LP Token System

Issues ERC20 liquidity provider tokens that represent proportional ownership in liquidity pools. These tokens can be transferred, traded, or used as collateral in other protocols.
