CDP Agentkit Toolkit

The CDP Agentkit toolkit contains tools that enable an LLM agent to interact with the Coinbase Developer Platform. The toolkit provides a wrapper around the CDP SDK, allowing agents to perform onchain operations like transfers, trades, and smart contract interactions.

Overview​

Integration details​

ClassPackageSerializableJS supportPackage latest
CdpToolkitcdp-langchain❌❌PyPI - Version

Tool features​

The toolkit provides the following tools:

  1. get_wallet_details - Get details about the MPC Wallet
  2. get_balance - Get balance for specific assets
  3. request_faucet_funds - Request test tokens from faucet
  4. transfer - Transfer assets between addresses
  5. trade - Trade assets (Mainnet only)
  6. deploy_token - Deploy ERC-20 token contracts
  7. mint_nft - Mint NFTs from existing contracts
  8. deploy_nft - Deploy new NFT contracts
  9. register_basename - Register a basename for the wallet

We encourage you to add your own tools, both using CDP and web2 APIs, to create an agent that is tailored to your needs.

Setup​

At a high-level, we will:

  1. Install the langchain package
  2. Set up your CDP API credentials
  3. Initialize the CDP wrapper and toolkit
  4. Pass the tools to your agent with toolkit.get_tools()

If you want to get automated tracing from runs of individual tools, you can also set your LangSmith API key by uncommenting below:

# os.environ["LANGSMITH_API_KEY"] = getpass.getpass("Enter your LangSmith API key: ")
# os.environ["LANGSMITH_TRACING"] = "true"

Installation​

This toolkit lives in the cdp-langchain package:

%pip install -qU cdp-langchain

Set Environment Variables​

To use this toolkit, you must first set the following environment variables to access the CDP APIs to create wallets and interact onchain. You can sign up for an API key for free on the CDP Portal:

import getpass
import os

for env_var in [
    "CDP_API_KEY_NAME",
    "CDP_API_KEY_PRIVATE_KEY",
]:
    if not os.getenv(env_var):
        os.environ[env_var] = getpass.getpass(f"Enter your {env_var}: ")

# Optional: Set network (defaults to base-sepolia)
os.environ["NETWORK_ID"] = "base-sepolia"  # or "base-mainnet"

Instantiation​

Now we can instantiate our toolkit:

from cdp_langchain.agent_toolkits import CdpToolkit
from cdp_langchain.utils import CdpAgentkitWrapper

# Initialize CDP wrapper
cdp = CdpAgentkitWrapper()

# Create toolkit from wrapper
toolkit = CdpToolkit.from_cdp_agentkit_wrapper(cdp)

Tools​

View available tools:

tools = toolkit.get_tools()
for tool in tools:
    print(tool.name)

Use within an agent​

We will need a LLM or chat model:

from langchain_openai import ChatOpenAI

llm = ChatOpenAI(model="gpt-4o-mini")
API Reference:ChatOpenAI

Initialize the agent with the tools:

from langgraph.prebuilt import create_react_agent

tools = toolkit.get_tools()
agent_executor = create_react_agent(llm, tools)
API Reference:create_react_agent

Example usage:

example_query = "Send 0.005 ETH to john2879.base.eth"

events = agent_executor.stream(
    {"messages": [("user", example_query)]},
    stream_mode="values",
)
for event in events:
    event["messages"][-1].pretty_print()

Expected output:

Transferred 0.005 of eth to john2879.base.eth.
Transaction hash for the transfer: 0x78c7c2878659a0de216d0764fc87eff0d38b47f3315fa02ba493a83d8e782d1e
Transaction link for the transfer: https://sepolia.basescan.org/tx/0x78c7c2878659a0de216d0764fc87eff0d38b47f3315fa02ba493a83d8e782d1

CDP Toolkit Specific Features​

Wallet Management​

The toolkit maintains an MPC wallet. The wallet data can be exported and imported to persist between sessions:

# Export wallet data
wallet_data = cdp.export_wallet()

# Import wallet data
values = {"cdp_wallet_data": wallet_data}
cdp = CdpAgentkitWrapper(**values)

Network Support​

The toolkit supports multiple networks

Gasless Transactions​

Some operations support gasless transactions on Base Mainnet:

  • USDC transfers
  • EURC transfers
  • cbBTC transfers
