Uniswap/v3-core
V3 Core
This project is a decentralized exchange core and Ethereum automated market maker providing the foundational on-chain logic for managing liquidity pools and executing token swaps. It implements an ERC-20 token swap engine and an on-chain liquidity manager to facilitate the exchange of standardized fungible tokens.
The system utilizes a concentrated liquidity protocol, allowing providers to allocate assets within specific price ranges to increase capital efficiency. It employs a constant product formula for price calculation and a tick-based tracking system to manage liquidity distribution. Unique liquidity positions are tracked as non-fungible tokens, and the architecture includes on-chain oracles for time-weighted average prices.
The platform covers broad capabilities across swap routing, liquidity management, and security. It supports multi-path swap quoting and intent-based order execution alongside tools for liquidity pool seeding and position calculation. Security is managed through token approval verification and a hook system that allows for custom smart contract logic during pool events.
The project is implemented primarily in TypeScript.
