MoonPay Brings Crypto Transactions to Claude and Codex With MoonAgents Desktop App

Claude and ChatGPT can write code—and MoonPay wants to make them trade crypto, too.

The crypto payments company on Wednesday launched the MoonAgents desktop app, a project that allows users to connect Anthropic’s Claude Code and OpenAI’s Codex to crypto wallets, token swaps, prediction markets, and other blockchain services through a visual interface.

"All that stuff is hidden under the hood for you," MoonPay Head of Agents Kevin Arifin told Decrypt. “It will set up Codex or Claude locally on your computer behind the scenes, and then it's a front end.”

MoonPay first launched MoonAgents in February as a command-line tool. Fast forward three months, and the desktop version moves those capabilities into a graphical interface that handles much of the setup behind the scenes.

According to Arifin, users can sign in with existing Claude or Codex accounts rather than manually configuring the underlying tools. The software includes prebuilt Skills, scheduled Automations, and an Artifacts system that can generate custom dashboards and other interfaces for managing financial activity.

However, as AI agents gain more autonomy, concerns about access and oversight have grown.

In April, PocketOS founder Jeremy Crane claimed a Cursor agent running Anthropic’s Claude Opus deleted production data and backups through a single Railway API call, leaving only a three-month-old recoverable backup. Security researchers have also warned about prompt injection attacks, which can trick AI agents into revealing sensitive information or performing actions the user never intended.

According to Arifin, MoonAgents addresses similar concerns by storing private keys locally, instead of on a cloud server.

“The most important piece of security is not revealing the private keys,” he said. “The private keys are stored locally on the user’s computer and are fully encrypted, so the LLM can’t just access or view them. All the keys are stored in such a way that there’s no way for the LLM to see those keys.”

The MoonAgents app is the latest ChatGPT-facing product produced by MoonPay. In May, MoonPay launched a new app that lets users buy cryptocurrencies, including Bitcoin and Solana, through ChatGPT just by speaking with the chatbot.

The biggest use case for the MoonAgents app, Arifin explained, is allowing AI models to run locally on a user's computer, where they can interact with blockchain services using the user's private keys without those credentials being exposed to the AI.

"The LLM is not the answer in this case," Arifin said. "It's empowering you to be able to do the research, dive into the meme coin, dive into the tokens, and dig into the trenches in a way that in the past it was only restricted to the people that could write scripts."
