+# @elizaos/plugin-quai
+
+Quai Network integration plugin for Eliza OS that enables native token transfers and interactions with the Quai blockchain.
+
+## Overview
+
+This plugin provides core functionality for interacting with the Quai Network, offering native token transfer capabilities and blockchain interactions through a simple interface.
+
+## Features
+
+- Native QUAI token transfers
+- Multiple network support
+- Secure transaction signing
+- Comprehensive error handling
+- Built-in address validation
+- Automatic gas estimation
+- Real-time transaction status
+
+## Installation
+
+```bash
+pnpm install @elizaos/plugin-quai
+```
+
+## Configuration
+
+The plugin requires the following environment variables:
+
+```env
+QUAI_PRIVATE_KEY=your-private-key
+QUAI_RPC_URL=https://rpc.quai.network  # or your preferred RPC endpoint
+```
+
+## Usage
+
+### Token Transfer
+
+```typescript
+import { quaiPlugin } from '@elizaos/plugin-quai';
+
+// Send QUAI
+const result = await eliza.execute({
+  action: 'SEND_TOKEN',
+  content: {
+    recipient: '0x049d36570d4e46f48e99674bd3fcc84644ddd6b96f7c741b1562b82f9e004dc7',
+    amount: '10'
+  }
+});
+```
+
+## API Reference
+
+### Actions
+
+#### `SEND_TOKEN`
+Transfers QUAI tokens to another address.
+
+```typescript
+{
+  action: 'SEND_TOKEN',
+  content: {
+    recipient: string,    // Recipient's Quai address (42 characters, 0x prefix)
+    amount: string,       // Amount to send (in QUAI)
+    tokenAddress?: string // Optional: for QRC20 tokens (not implemented yet)
+  }
+}
+```
+
+### Providers
+
+The plugin uses Quai's native JsonRpcProvider for blockchain interactions:
+
+```typescript
+const provider = getQuaiProvider(runtime);
+// Returns configured JsonRpcProvider instance
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Transaction Failures**
+   - Check account balance
+   - Verify recipient address format
+   - Ensure sufficient gas
+   - Confirm network connection
+
+2. **Connection Problems**
+   - Verify RPC endpoint
+   - Check network status
+   - Ensure valid credentials
+   - Monitor API availability
+
+3. **Configuration Issues**
+   - Verify environment variables
+   - Check address format
+   - Confirm private key format
+   - Validate RPC URL
+
+## Security Best Practices
+
+1. **Key Management**
+   - Store private keys securely
+   - Use environment variables
+   - Never expose private keys in code
+   - Monitor account activity
+
+2. **Transaction Safety**
+   - Validate all addresses
+   - Implement amount validation
+   - Double-check recipients
+   - Monitor transaction status
+
+3. **Error Handling**
+   - Log all transaction attempts
+   - Handle timeouts gracefully
+   - Validate all user inputs
+   - Provide clear error messages
+
+## Testing
+
+Run the test suite:
+
+```bash
+pnpm test
+```
+
+## Dependencies
+
