Agentkit

Coinbase AgentKit Skill

AgentKit is Coinbase's developer toolkit that enables AI agents to interact with blockchain networks through secure wallet management and comprehensive onchain capabilities. Built on the Coinbase Developer Platform (CDP) SDK, it provides everything needed to create autonomous agents that can perform sophisticated blockchain operations.

Core Mission: "Every AI agent deserves a wallet."

When to Use This Skill

This skill should be triggered when:

• Building AI agents with crypto wallet capabilities
• Creating autonomous agents that need to execute blockchain transactions
• Implementing token transfers, swaps, or DeFi operations in AI agents
• Deploying smart contracts or NFTs through AI agents
• Integrating LangChain, Vercel AI SDK, or MCP with blockchain functionality
• Building chatbots that can perform onchain actions
• Setting up agents with Coinbase CDP wallet infrastructure
• Creating multi-chain agents (EVM + Solana)
• Integrating x402 payment capabilities with AI agents

    erc20ActionProvider,
    compoundActionProvider({ networkId: "base-sepolia" }),
    walletActionProvider,
  ],
});

Framework Integrations

  "mcpServers": {
    "agentkit": {
      "command": "node",
      "args": ["/path/to/agentkit-mcp-server.js"],
      "env": {

  }
}

OpenAI Agents SDK Integration (Python)

from agents import Agent, Runner
from coinbase_agentkit import AgentKit, CdpWalletProvider
from coinbase_agentkit_openai_agents_sdk import get_openai_tools

# Setup AgentKit
wallet_provider = CdpWalletProvider.configure_with_wallet(
    network_id="base-sepolia"
)
agent_kit = AgentKit.from_config(wallet_provider=wallet_provider)

# Get OpenAI tools
tools = get_openai_tools(agent_kit)

# Create agent
agent = Agent(
    name="Crypto Agent",
    instructions="You are an AI agent with a crypto wallet. Help users with onchain operations.",
    tools=tools,
)

# Run agent
result = await Runner.run(agent, "What's my wallet address?")
print(result.final_output)

Common Patterns

Persisting Wallet Data

// Export wallet data for persistence
const walletData = await walletProvider.exportWallet();
// Store walletData securely (encrypted in database, etc.)

// Restore wallet from data
const restoredProvider = await CdpWalletProvider.configureWithWallet({
  networkId: "base-sepolia",
  cdpWalletData: walletData,
});

Creating Custom Action Providers

import { ActionProvider, CreateAction, ActionMetadata } from "@coinbase/agentkit";
import { z } from "zod";

class MyActionProvider extends ActionProvider {
  @CreateAction({
    name: "my_custom_action",
    description: "Does something custom",
    schema: z.object({
      param: z.string().describe("A parameter"),
    }),
  })
  async myCustomAction(params: { param: string }): Promise<string> {
    // Implementation
    return `Processed: ${params.param}`;
  }
}

// Register custom provider
const agentKit = await AgentKit.from({
  walletProvider,
  actionProviders: [new MyActionProvider()],
});

Multi-Chain Agent

// EVM wallet for Base
const evmProvider = await CdpWalletProvider.configureWithWallet({
  networkId: "base-sepolia",
});

// Solana wallet
const solanaProvider = await CdpV2SolanaWalletProvider.configureWithWallet({
  networkId: "solana-devnet",
});

// Create agents for each chain
const evmAgentKit = await AgentKit.from({ walletProvider: evmProvider });
const solanaAgentKit = await AgentKit.from({ walletProvider: solanaProvider });

x402 Payment Integration

import { AgentKit, CdpWalletProvider, x402ActionProvider } from "@coinbase/agentkit";

const agentKit = await AgentKit.from({
  walletProvider,
  actionProviders: [x402ActionProvider],
});

// Agent can now make x402 payments for paid APIs

CLI Tools

TypeScript CLI

# Install globally
npm install -g @coinbase/agentkit

# Generate components
agentkit generate wallet-provider    # Custom wallet provider
agentkit generate action-provider    # Custom action provider
agentkit generate prepare            # Framework-agnostic setup
agentkit generate create-agent       # Framework-specific agent

Python CLI

# Create new project
pipx run create-onchain-agent

# With beginner defaults
pipx run create-onchain-agent --beginner

Security Considerations

• Wallet Isolation: Each agent should have its own dedicated wallet
• Fund Limits: Only fund agent wallets with amounts needed for operations
• Key Management: Store CDP API keys and wallet data securely
• Network Selection: Use testnets (base-sepolia, solana-devnet) for development
• Action Auditing: Log all agent actions for review

Important Disclaimer: "Acts proposed or performed by an agent through AgentKit software are NOT acts of Coinbase." Use at your own risk.
