   npm i @iqai/plugin-wallet

   pnpm

   pnpm add @iqai/plugin-wallet

   yarn

   yarn add @iqai/plugin-wallet

2. Create a .env file with the required configuration:

   COVALENT_API_KEY=your-covalent-api-key
   WALLET_ADDRESS=your-wallet-address

---

Basic Setup

Here’s a complete example of setting up your agent with the Wallet Plugin:

import { createWalletPlugin } from "@iqai/plugin-wallet";

async function main() {
  // Initialize Wallet Plugin
  const walletPlugin = await createWalletPlugin({
    covalentApiKey: process.env.COVALENT_API_KEY,
    walletAddress: process.env.WALLET_ADDRESS,
  });

  // Integrate walletPlugin with your agent or system
  const agent = new AgentBuilder().withPlugin(walletPlugin).build();
  await agent.start();
}

main().catch(console.error);

Available Operations

• Holdings Retrieval: Fetch token balances for a wallet
• Transaction History: Retrieve transaction details including timestamps, status, and gas information

The Wallet Plugin accepts the following configuration parameters:

interface WalletPluginConfig {
  covalentApiKey: string;    // Covalent API key for blockchain data access
  walletAddress: string;   // Default wallet address
}

Error Handling

Always implement proper error handling when using the plugin:

try {
  const walletPlugin = await createWalletPlugin({
    covalentApiKey: process.env.COVALENT_API_KEY,
    walletAddress: process.env.WALLET_ADDRESS,
  });
} catch (error) {
  console.error('Failed to initialize Wallet Plugin:', error);
}

Best Practices

• Chain Validation: Verify supported chain names before making requests
• Address Verification: Ensure wallet addresses are correct and valid
• Rate Limit Awareness: Handle API rate limits according to Covalent guidelines
• Security Measures: Keep your API key secure and never expose it publicly

---

Common Issues and Troubleshooting

• Invalid Chain Name: Ensure you’re using supported chain names as per the Covalent API documentation.
• Missing Wallet Address: If required, provide a valid wallet address.
• API Connection Errors: Check your network connectivity and API key validity.
• Rate Limiting: Be aware of the API rate limits and implement retries or backoff mechanisms.
