Prerequisites

• Node.js v18+
• Hardhat
• Metamask wallet
• Brian API key
• Polygon Amoy (POS) testnet/Mainnet RPC

Setup Instructions

1. Clone the repository
2. Install dependencies:

   npm install

3. Configure environment variables:

   cp .env.example .env

4. Add your API keys and configuration to .env

Development

1. Start the local hardhat node:

   npx hardhat node

2. Deploy contracts:

   npx hardhat run scripts/deploy.js --network polygon

3. Start the frontend:

   cd frontend
   npm run dev

Architecture

The system consists of three main components:

1. AI Agent Core: Interfaces with Brian's API for intelligent decision-making
2. Bridge Interface: Manages cross-chain transactions using Unified Bridge (WIP)
3. DeFi Operations: Handles automated DeFi interactions

Security Considerations

• All sensitive operations require user confirmation
• API keys are stored securely
• Rate limiting for AI operations
• Secure bridge transaction validation (WIP)
