Uniswap V3 Periphery provides essential auxiliary smart contracts for the Uniswap V3 Protocol, complementing the foundational elements found in the uniswap-v3-core repository. This repository enables developers to locally deploy Uniswap V3 compatible systems by installing the @uniswap/v3-periphery npm package, leveraging bytecode artifacts for seamless integration with mainnet and public testnets. Security and reliability are underscored by its inclusion in the Uniswap V3 bug bounty program. Developers can enhance their Solidity projects using tailored interfaces available through the package, facilitating sophisticated interactions such as token swaps via the Swap Router contract.
