OmniStrat AI

AI-powered DeFi strategy assistant that unifies cross-chain operations through natural language. Ask it to swap tokens, bridge USDC, supply to lending protocols, or manage state channels, all from a single chat interface.

Built for Hack Money 2026 by ETHGlobal.

Features

• Natural Language DeFi: Describe what you want ("swap 100 USDC to ETH on Arbitrum") and the AI builds and presents the transactions for you to approve
• Cross-Chain Swaps & Bridges: Token swaps and bridges across 10+ chains via LI.FI with route comparison and gas estimation
• Unified USDC Balance: View and manage a single USDC balance across all chains using Circle Gateway
• Native USDC Bridging: Burn-and-mint USDC transfers via Circle CCTP v2, no wrapped tokens
• Aave v3 Lending: Supply and withdraw assets on Aave v3 with position tracking across chains
• ENS Identity: Resolve ENS names, read on-chain profiles, and store DeFi preferences as ENS text records
• Yellow Network State Channels: Instant, gas-free off-chain operations with on-chain settlement
• Multi-Model AI: Supports OpenAI GPT-4o and Google Gemini 2.0 Flash (configurable via env var)

How it works: The AI model receives tool definitions (Vercel AI SDK tool() with Zod schemas). When a user asks to perform a DeFi action, the model calls the appropriate tool server-side. Tools return transaction data (calldata, target address, value) which the frontend presents for the user to sign with their connected wallet.

Tech Stack

• Framework: Next.js 16 (App Router), React 19, TypeScript 5
• AI: Vercel AI SDK v3 with tool calling
• Web3: wagmi v3, viem v2
• Styling: Tailwind CSS v4
• State: TanStack React Query v5

Getting Started

Prerequisites

• Node.js 18+
• A browser wallet (MetaMask, etc.)

Setup

git clone https://github.com/Raj-RR1/omnistrat-ai.git
cd omnistrat-ai
npm install

Create .env.local:

# AI model — choose one
MODEL_PROVIDER=openai          # or "gemini"
OPENAI_API_KEY=sk-...          # required if using openai
GOOGLE_GENERATIVE_AI_API_KEY=  # required if using gemini

Run

GOOGLE_GENERATIVE_AI_API_KEY=xxxxxxxxxxxx # required if using gemini

npm run dev

Open http://localhost:3000, connect your wallet, and start chatting.
