}Core Components
AgentKit Integration
The CDP Agent utilizes Coinbase's AgentKit to provide secure blockchain interactions:
const agentkit = await AgentKit.from({
walletProvider: viemWalletProvider,
actionProviders: [
walletActionProvider(),
erc20ActionProvider(),
wethActionProvider(),
pythActionProvider(),
cowSwapActionProvider(),
wormholeActionProvider(),
defiActionProvider(),
cdpApiActionProvider()
]
});React Agent
The agent implements a React pattern for AI-powered decision making:
const agent = createReactAgent({
llm: groqModel,
tools: langChainTools,
checkpointSaver: memorySaver,
messageModifier: `You are a helpful agent that can interact onchain using the Coinbase Developer Platform AgentKit...`
});Event System
The CDP Agent integrates with Ava's event-driven architecture:

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);Configuration
