Using Action Providers

typescript
import {
  AgentKit,
  CdpWalletProvider,
  cdpApiActionProvider,
  erc20ActionProvider,
  compoundActionProvider,
  walletActionProvider,
  x402ActionProvider,
  superfluidActionProvider,
} from "@coinbase/agentkit";

const agentKit = await AgentKit.from({
  walletProvider,
  actionProviders: [
    cdpApiActionProvider,
    erc20ActionProvider,
    compoundActionProvider({ networkId: "base-sepolia" }),
    walletActionProvider,
    x402ActionProvider,
    superfluidActionProvider,
  ],
});

Smart Wallets & Gasless Transactions

Smart Wallets are ERC-4337 compliant smart contract wallets providing:

• Gasless transactions - No ETH required for gas fees
• Batch operations - Multiple actions in one transaction
• Account recovery - Secure recovery mechanisms
• Sponsored transactions - Via paymaster integration

Note: Smart Wallets are currently only supported on Base networks (base-sepolia, base-mainnet).

typescript
import { CdpSmartWalletProvider } from "@coinbase/agentkit";

// Configure Smart Wallet with gasless transactions
const smartWalletProvider = await CdpSmartWalletProvider.configureWithWallet({
  networkId: "base-mainnet",
  // Enable gasless via paymaster
  paymasterUrl: "https://your-paymaster.example.com",
});

// Create AgentKit with smart wallet
const agentKit = await AgentKit.from({
  walletProvider: smartWalletProvider,
  actionProviders: [walletActionProvider, erc20ActionProvider],
});

// Agent can now transact without holding ETH for gas

OpenAI Agents SDK Integration (Python)

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)

Supported Networks

EVM Networks

| Network | ID | Status | |---------|----|--------| | Base Mainnet | base-mainnet | Production | | Base Sepolia | base-sepolia | Testnet | | Ethereum Mainnet | ethereum-mainnet | Production | | Ethereum Sepolia | ethereum-sepolia | Testnet | | Arbitrum | arbitrum-mainnet | Production | | Optimism | optimism-mainnet | Production | | Polygon | polygon-mainnet | Production |

SVM Networks

| Network | ID | Status | |---------|----|--------| | Solana Mainnet | solana-mainnet | Production | | Solana Devnet | solana-devnet | Testnet | | Solana Testnet | solana-testnet | Testnet |

Common Patterns

Persisting Wallet Data

typescript
// 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

typescript
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()],
});

Python Custom Action Provider

python
from coinbase_agentkit import ActionProvider, create_action
from pydantic import BaseModel

class MyParams(BaseModel):
    param: str

class MyActionProvider(ActionProvider):
    @create_action(
        name="my_custom_action",
        description="Does something custom",
        schema=MyParams,
    )
    async def my_custom_action(self, params: MyParams) -> str:
        return f"Processed: {params.param}"

Multi-Chain Agent

typescript
// 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

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

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

// Agent can now make x402 payments for paid APIs

Idempotent Wallet Creation

typescript
// Create deterministic wallet using idempotency key
const walletProvider = await CdpWalletProvider.configureWithWallet({
  networkId: "base-sepolia",
  idempotencyKey: "user-123-wallet",  // Same key always returns same wallet
});

CLI Tools

TypeScript CLI

bash
# 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

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
• Smart Wallet Benefits: Use Smart Wallets for enhanced security features

Important Disclaimer: "Acts proposed or performed by an agent through AgentKit software are NOT acts of Coinbase." Use at your own risk. The software is novel and experimental, provided on an AS-IS basis.
