Coinbase AgentKit
Coinbase AgentKit is a toolkit so AI agents can hold wallets and take onchain actions. Official CDP docs (now under /agent-kit/welcome) say it is built on the Coinbase Developer Platform SDK and covers secure wallet management, transfers, swaps, contract deploys, and more. It is framework-agnostic (LangChain, Eliza, Vercel AI SDK, and others) and supports EVM networks plus Solana. The GitHub repo coinbase/agentkit had about 1,283 stars on 2026-08-17 and was still receiving commits. Marketing line: "Every AI Agent deserves a wallet."
Key Features
- Wallets for agents: Create and manage wallets through CDP rather than pasting raw keys into prompts.
- Onchain actions: Transfers, swaps, smart contract work, plus custom action providers.
- Any framework: Docs list LangChain, Eliza, Vercel AI SDK, and extensibility for others.
- EVM and Solana: Not Base-only, despite USDC-on-Base examples in older posts.
- TypeScript and Python: Action providers in both languages remain the integration path.
Use Cases
- Agents that must pay or get paid onchain without a human clicking MetaMask.
- Demo bots on Base that send USDC, then graduate to another EVM or Solana.
- Custom contract calls via your own action provider.
Pricing
AgentKit itself is open source. You pay network fees, CDP wallet/API usage, and any Coinbase Developer Platform plan attached to the project. The welcome page we fetched does not publish a seat price. Confirm CDP billing in the console. Do not reprint "fee-free USDC on Base" as a forever guarantee.
Getting Started
- Read the AgentKit overview.
- Follow the 5-minute quickstart linked from that page.
- Create a CDP wallet for the agent, then attach one framework adapter.
- Add only the action providers you need (transfer first, swaps later).
Frequently Asked Questions
Is AgentKit archived?
No. The repo was active as of 2026-08-13.
LangChain only?
No. Official copy says any AI framework, with LangChain and Eliza called out.
How is it different from Stripe agents?
Stripe is card and billing rails plus MCP. AgentKit is wallets and onchain calls.
Alternatives
- Coinbase Agentic Wallets: Wallet product next to the toolkit.
- Stripe Agent Toolkit: Offchain payments and MCP.
- x402: HTTP 402 payment required for agents.
Tips
- Start on a testnet. Agent wallets still sign real transactions when you point them at mainnet.
- Limit action providers. A swap-enabled agent is a different risk class.
- Confirm the docs path. Coinbase moved AgentKit under
/agent-kit/.
Conclusion
AgentKit is still the Coinbase way to put a wallet on an agent. Start at the CDP overview, then clone coinbase/agentkit for the adapters.
