# CLAUDE.md - uniswap-trading Plugin

## Overview

This plugin provides comprehensive guidance for integrating Uniswap swaps into frontends, backends, and smart contracts. It supports the Trading API, Universal Router SDK, and direct smart contract integration.

## Plugin Components

### Skills (./skills/)

- **swap-integration**: Comprehensive guide for integrating Uniswap swaps via Trading API, Universal Router SDK, or direct smart contract calls. Covers frontend hooks, backend scripts, Solidity integrations, Permit2 patterns, ERC-4337 smart account integration, L2 WETH handling, rate limiting, and troubleshooting.

### Agents (./agents/)

- **swap-integration-expert**: Expert agent for complex Uniswap swap integration questions, Trading API debugging, Universal Router encoding, Permit2 patterns, ERC-4337 smart account integration, and L2-specific patterns.

## Integration Methods

1. **Trading API** (Recommended for most use cases)

   - REST API at `https://trade-api.gateway.uniswap.org/v1`
   - Handles routing optimization automatically
   - 3-step flow: check_approval -> quote -> swap

2. **Universal Router SDK**

   - Direct SDK usage with `@uniswap/universal-router-sdk`
   - Full control over transaction construction
   - Command-based architecture

3. **Direct Smart Contract Integration**
   - Solidity contracts calling Universal Router
   - For on-chain integrations and DeFi composability

## Supported Chains

Ethereum (1), Optimism (10), BNB (56), Unichain (130), Polygon (137), X Layer (196), zkSync (324), World Chain (480), Soneium (1868), Base (8453), Arbitrum (42161), Celo (42220), Avalanche (43114), Blast (81457), Zora (7777777), Monad (143)
