# ๐ Omeswap โ Mantle DEX
**Omeswap** is a next-generation decentralized exchange (DEX) and DeFi platform built natively on **Mantle Network (L2)**. It combines a fully functional Uniswap V2-style Automated Market Maker (AMM) with advanced portfolio analytics, token research tools, and a visual AI agent builder โ all wrapped in a stunning, modern interface.
## ๐ Project Overview
Omeswap is designed to be the all-in-one DeFi hub for traders, liquidity providers, and developers on Mantle. Unlike traditional DEXs that only offer swapping functionality, Omeswap provides:
1. **Decentralized Trading** โ Swap tokens with optimal routing through multi-hop paths
2. **Liquidity Management** โ Provide liquidity to pools and earn trading fees
3. **Portfolio Tracking** โ Real-time wallet analysis across multiple chains
4. **Token Research** โ Deep token analytics with audit scores, charts, and fundamental analysis
5. **DEX Explorer** โ Browse all pools, tokens, and transactions on the protocol
6. **AI Agent Builder** โ Visually design and deploy automated trading strategies
