Agentkit is a software toolkit from Coinbase for building AI agents that handle cryptocurrency transactions

Agentkit is an open-source set of tools released by Coinbase, the cryptocurrency exchange company. It lets developers write code that creates AI agents — programs that can act on their own to perform tasks like sending cryptocurrency, checking balances, or executing trades. You do not use Agentkit yourself; developers use it to build applications that might eventually serve you.

The toolkit sits on top of Claude, an AI model made by Anthropic. This means a developer can write instructions in plain language, and Claude interprets those instructions and uses Agentkit's tools to carry them out on the blockchain — the public ledger where cryptocurrency transactions live. Think of it as a bridge between what a developer wants an AI to do and the actual cryptocurrency network where the money moves.

Agentkit is free and publicly available. Coinbase released it because they want developers to experiment with AI agents in the cryptocurrency space. The code is open-source, meaning anyone can read it, modify it, and build on top of it.

Key Takeaways

  • Agentkit is a free toolkit from Coinbase that developers use to build AI agents capable of handling cryptocurrency transactions.
  • The code is open-source and publicly available on GitHub, so you can read it or read it without paying anything.
  • Agentkit works with Claude, Anthropic's AI model, to let developers give natural language instructions that the AI carries out on the blockchain.
  • You encounter Agentkit indirectly — through applications a developer built with it — not by using it directly yourself.

Where to find the Agentkit code and documentation

The official Agentkit repository lives on GitHub under the Coinbase organization. GitHub is a platform where developers store and share code. You can visit the repository by searching "Coinbase Agentkit" or going directly to the Coinbase GitHub page and looking for the Agentkit project.

The repository includes the actual code, a README file that explains what Agentkit does, and documentation that walks a developer through setup and basic use. If you are not a developer, reading the README gives you a plain-language sense of what the toolkit is for. The documentation is written for people who know how to code, so it will be technical.

Coinbase also maintains information about Agentkit on their main website and developer portal. A search for "Coinbase Agentkit" will surface these official pages, which often include blog posts or announcements about new features or updates to the toolkit.

How developers actually use Agentkit

A developer starts by downloading Agentkit from GitHub and installing it on their computer. They then write code that imports Agentkit's tools and connects them to Claude. The developer gives Claude instructions in plain English — for example, "send 0.5 ETH to this wallet address" — and Claude uses Agentkit to translate that instruction into a real transaction on the blockchain.

Agentkit handles the technical details: connecting to the cryptocurrency network, signing transactions so they are authentic, and managing the wallet that holds the cryptocurrency. The developer does not have to write all that code from scratch. They focus on what they want the AI agent to do, and Agentkit provides the tools to do it.

This matters because cryptocurrency transactions are irreversible and involve real money. Agentkit is built to handle that responsibility — it includes safety checks and standard practices so a developer does not accidentally send funds to the wrong place or leave a wallet exposed to theft.

What Agentkit can and cannot do

Agentkit can handle tasks like checking a wallet balance, sending cryptocurrency to another wallet, swapping one cryptocurrency for another, and reading information from the blockchain. It works with Coinbase's own services and with the broader Ethereum blockchain, which is where many cryptocurrency applications run.

Agentkit cannot do things outside the cryptocurrency world. It cannot access your email, control your bank account, or interact with systems that are not connected to the blockchain. It is purpose-built for one job: letting an AI agent move money and read transaction history on cryptocurrency networks.

The toolkit also cannot make decisions on its own about whether a transaction is wise or safe. A developer has to write the logic that decides when and how the AI agent acts. If a developer writes bad logic, Agentkit will faithfully carry out the bad instructions. The responsibility for what the AI agent does rests with the developer who built it.

Why Coinbase released Agentkit

Coinbase released Agentkit because the company sees AI agents as the future of cryptocurrency applications. Right now, most people interact with cryptocurrency through a website or app that a human designed. Coinbase believes that in the future, people will give instructions to AI agents, and those agents will handle the details.

By releasing Agentkit for free, Coinbase is encouraging developers to experiment with this idea. The more developers who build with Agentkit, the more applications exist that use it, and the more people encounter AI agents handling cryptocurrency. This benefits Coinbase because many of those applications will likely use Coinbase's services underneath.

It is also a way for Coinbase to shape how AI agents work in the cryptocurrency space. By providing a toolkit that reflects their values and design choices, they influence what kinds of applications get built and how they behave.

The difference between Agentkit and other AI tools

Many companies have released AI tools in recent years. ChatGPT, for example, is an AI you can talk to, but it cannot move money or interact with the blockchain. Agentkit is different because it is specifically designed to give an AI agent the ability to take action in the cryptocurrency world.

Other AI frameworks let developers build agents that can do many things — send emails, control smart home devices, manage calendars. Agentkit is narrower: it focuses only on cryptocurrency. This makes it simpler for a developer who wants to build a cryptocurrency agent, because they do not have to figure out which tools to use or how to connect them. Agentkit does that work.

Agentkit also pairs specifically with Claude, Anthropic's AI model. A developer could theoretically use other AI models with Agentkit's tools, but Coinbase designed and tested Agentkit with Claude in mind, so that combination works best.

Frequently Asked Questions

Do I need to know how to code to use Agentkit?

Yes. Agentkit is a toolkit for developers. If you are not a programmer, you cannot use it directly. You would use an process that a developer built with Agentkit, but you would not interact with Agentkit itself.

Does Agentkit cost money?

No. Agentkit itself is free and open-source. However, using it may involve costs elsewhere — for example, you might pay to run Claude through Anthropic's API, or you might pay transaction fees when the AI agent moves cryptocurrency on the blockchain.

Is Agentkit affiliated with or endorsed by the government?

No. Agentkit is a product made by Coinbase, a private company. It is not a government tool or service.

Can Agentkit access my personal bank account or financial information?

No. Agentkit only works with cryptocurrency on the blockchain. It cannot connect to traditional banks, credit cards, or non-blockchain financial systems.

What happens if an AI agent built with Agentkit makes a mistake and sends money to the wrong place?

Cryptocurrency transactions are permanent and cannot be reversed. If a developer wrote code that caused the AI agent to send funds incorrectly, the money is gone. This is why developers have a responsibility to test their code carefully and write clear logic about when and how the agent acts.
