Configuration

Configure environment variables and settings for MetaVault AI

Overview

MetaVault AI requires configuration across three packages. Each package has its own .env file with specific settings.

Contracts Configuration

The contracts package requires minimal configuration for deployment.

1. Create Environment File

   cd packages/contracts
   cp .env.example .env
   
2. Configure Variables

   Edit packages/contracts/.env:

   # Deployer Wallet Private Key (for local development)
   PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
   
   # INFURA API Key (for testnet/mainnet deployment)
   INFURA_KEY=your_infura_api_key
   

   The private key shown above is the first Hardhat test account. Never use it on mainnet or with real funds.

Configuration Reference

PRIVATE_KEY · string · required

Private key of the wallet that will deploy contracts.

For local development, use one of Hardhat’s test account private keys.

INFURA_KEY · string

Your Infura API key for connecting to Ethereum networks.

Only required for testnet or mainnet deployments. Get one at infura.io.

AI Agents Configuration

The agents package requires the most configuration, including API keys and contract addresses.

1. Create Environment File

   cd packages/agents/defi-portfolio
   cp .env.example .env
   
2. Configure Core Settings

   Edit packages/agents/defi-portfolio/.env:

   # Debug Mode
   ADK_DEBUG="false"
   
   # OpenRouter API Key (Required)
   OPEN_ROUTER_KEY=your_openrouter_api_key
   
   # LLM Model
   LLM_MODEL=anthropic/claude-3.5-sonnet
   
   # Server Ports
   PORT=3001
   CHAT_PORT=3002
   

   Get your OpenRouter API key at openrouter.ai

3. Configure Blockchain Connection

   Add blockchain settings:

   # RPC URL
   RPC_URL=http://127.0.0.1:8545
   
   # Vault Deployer Wallet Private Key
   PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
   
4. Configure Contract Addresses

   Add the contract addresses from your deployment:

   # CORE CONTRACTS
   VAULT_ADDRESS=0x5FbDB2315678afecb367f032d93F642f64180aa3
   ROUTER_ADDRESS=0xe7f1725E7734CE288F8367e1Bb143E90bb3F0512

   # Mock TOKEN
   LINK_ADDRESS=0x5FC8d32690cc91D4c39d9d3abcBD16989F875707
   
   # Mock AAVE POOL
   MOCK_AAVE_POOL_ADDRESS=0x0165878A594ca255338adfa4d48449f69242Eb8F
   

   Replace these example addresses with the actual addresses from your deployment output.

5. Configure Telegram (Optional)

   For Telegram notifications:

   # Telegram Bot Token & Chat/Channel ID
   TELEGRAM_BOT_TOKEN=your_bot_token
   TELEGRAM_CHANNEL_ID=your_channel_id
   

   Create a Telegram bot via @BotFather to get your bot token.

Environment-Specific Configuration

Local Development

Use Hardhat’s local network:

RPC_URL=http://127.0.0.1:8545

Use Hardhat’s first test account:

PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80

Testnet

Use a testnet RPC (e.g., Sepolia via Infura):

RPC_URL=https://sepolia.infura.io/v3/YOUR_INFURA_KEY

Use your testnet wallet private key:

PRIVATE_KEY=your_testnet_private_key

Never commit private keys to version control. Use environment variables or secret management.

Mainnet

Use a mainnet RPC:

RPC_URL=https://mainnet.infura.io/v3/YOUR_INFURA_KEY

Use a secure wallet and never expose your mainnet private key. Consider using a hardware wallet or secure key management service.

Validation

After configuration, verify your setup:

Contracts

cd packages/contracts
pnpm hardhat compile

If all builds succeed, your configuration is correct.

Troubleshooting

Invalid RPC URL

Ensure your Hardhat node is running:

cd packages/contracts
pnpm hardhat node

Contract Address Not Found

Make sure you’ve deployed the contracts:

cd packages/contracts
pnpm hardhat run scripts/deploy_mocks.ts --network localhost

Copy the addresses from the deployment output to your .env files.

OpenRouter API Error

Verify your OpenRouter API key is correct and has credits.

Check your account at openrouter.ai.

Port Already in Use

Change the PORT variables in your configuration:

PORT=3003
CHAT_PORT=3004
