## What it is
Peripheral smart contracts for the Uniswap V3 protocol, including the SwapRouter, nonfungible position manager, and related interfaces. Distributed as an npm package for deploying locally or importing Solidity interfaces into other contracts.

## Use cases
- integrate uniswap v3 swaps into my smart contract
- deploy a local testnet copy of uniswap v3 periphery contracts
- import ISwapRouter interface into solidity
- build a dapp that interacts with uniswap v3 positions
- swap tokens programmatically on ethereum via uniswap v3
- manage liquidity positions with the nonfungible position manager

## When to choose
- you are building smart contracts or dapps that need to interact with Uniswap V3
- you need the exact mainnet bytecode for local testing
- you want audited, bug-bounty-backed contract interfaces

## When to avoid
- you need the core Uniswap V3 pool contracts themselves (use uniswap-v3-core)
- you only need off-chain quoting or routing (consider the Uniswap SDKs instead)
- you are building on a non-EVM chain
