Usage Examples

Token Swapping

// Natural language request
"Swap 100 USDC for ETH on Ethereum mainnet"

// CDP Agent processes this as:
{
  operation: "swap",
  params: {
    fromToken: "USDC",
    toToken: "ETH", 
    amount: "100",
    chain: "ethereum"
  }
}

Cross-Chain Transfer

// Natural language request
"Bridge 0.5 ETH from Ethereum to Base"

// CDP Agent processes this as:
{
  operation: "bridge",
  params: {
    token: "ETH",
    amount: "0.5",
    sourceChain: "ethereum",
    destinationChain: "base"
  }
}

DeFi Operations

// Natural language request
"Provide liquidity to the ETH/USDC pool on Uniswap"

// CDP Agent processes this as:
{
  operation: "addLiquidity",
  params: {
    protocol: "uniswap",
    tokenA: "ETH",
    tokenB: "USDC",
    pool: "ETH/USDC"
  }
}

Integration Points

Task Manager Integration

The CDP Agent receives tasks from the Task Manager agent:

eventBus.on('task-manager-cdp-agent', async (data) => {
  const { taskId, task, type } = data;
  
  // Process the task using AI
  const result = await this.executeTask(task);
  
  // Return results to Task Manager
  eventBus.emit('cdp-agent-task-manager', {
    taskId,
    result,
    status: 'completed'
  });
});

Frontend Communication

Real-time updates to the frontend:

// Task start notification
this.emitToFrontend({
  type: 'TASK_STARTED',
  taskId,
  message: `Starting to process: ${task}`,
  timestamp: new Date().toISOString()
});

// Task completion notification
this.emitToFrontend({
  type: 'TASK_COMPLETED',
  taskId,
  result,
  timestamp: new Date().toISOString()
});

IP Licensing System

Automated intellectual property licensing:

// License agent responses
const licenseTerm: IPLicenseTerms = {
  name: `CDP Agent Response - ${Date.now()}`,
  description: "License for CDP agent's response",
  scope: 'commercial',
  transferability: true,
  onchain_enforcement: true,
  royalty_rate: 0.05
};

const licenseId = await this.mintLicense(licenseTerms, metadata);
