Coinbase Base Introduces AI-Powered Crypto Wallet Integration for ChatGPT and Claude

Key Highlights

• Base network from Coinbase has introduced Base MCP, enabling AI assistants such as ChatGPT and Claude to interface with cryptocurrency wallets.
• Through conversational commands, users can transfer assets, exchange tokens, view account balances and engage with decentralized finance platforms.
• Initial integration includes support for DeFi protocols such as Uniswap, Morpho, Moonwell and Avantis.
• All transactions require explicit user approval — AI assistants never gain access to private wallet keys.
• The x402 agentic payment system, which Base MCP builds upon, has recorded only $1.1 million in transaction volume during the last 30 days.

The Ethereum Layer 2 solution from Coinbase, known as Base, has unveiled Base MCP, an innovative integration that enables artificial intelligence platforms including ChatGPT and Claude to communicate directly with cryptocurrency wallets and decentralized financial applications.

This integration leverages the Model Context Protocol (MCP), an established framework designed to facilitate secure connections between AI systems and external applications.

Through simple conversational requests, users can instruct an AI agent to execute various operations including fund transfers, token swaps, balance inquiries, or transaction history reviews — all without navigating traditional cryptocurrency interfaces.

The initial release supports multiple DeFi protocols operating on Base. These encompass lending services Morpho and Moonwell, decentralized trading platform Uniswap, and derivatives exchange Avantis. Additional supported platforms include Aerodrome, Bankr and Virtuals.

Transaction Execution Process

When users submit requests, the AI assistant formulates a proposed action within the chat interface. Subsequently, the Base wallet appears in a separate window where users can either approve or reject the transaction.

Private keys remain exclusively under user control. Each operation undergoes the identical verification process used for standard Base account transactions. Additionally, asset modifications are previewed through simulation before user confirmation.

Lincoln Murr, who leads AI Product development at Coinbase, emphasized that the Base Account maintains continuity across platforms. He distinguished it from “isolated agentic wallets confined to terminal environments,” noting that trading activity, transaction records, and portfolio information remain synchronized across both the AI agent interface and the Base application.

Base positioned this release as advancing toward AI-integrated internet experiences. The organization expressed confidence that conversational agent interfaces will emerge as a primary channel for users to explore and utilize blockchain-based applications.

Development Phase and Security Considerations

Base MCP also advances the adoption of x402, an agentic AI payment framework introduced by Coinbase in May 2025. Murr characterized MCP as a “convenient wrapper” built upon existing application programming interfaces.

Combined with x402, this technology aims to facilitate small-scale cryptocurrency micropayments executed by AI agents. Nevertheless, x402 remains in nascent stages. Information from x402scan indicates the framework has handled merely $1.1 million in total volume throughout the previous 30 days.

The deployment of AI agents for cryptocurrency transactions has attracted scrutiny. Recent research from Google alongside multiple academic institutions cautioned that AI agents should be regarded as potentially untrusted system elements. Researchers emphasized that agents must maintain clear boundaries between instructions and untrusted information to prevent attackers from embedding malicious commands.

Just days ago, developer infrastructure provider Socket identified malware specifically designed to target cryptocurrency developers. This malicious software embedded concealed instructions intended to compromise AI-powered coding tools.

While Base has not addressed these particular security discoveries directly, the organization confirmed that every Base MCP transaction undergoes its established user verification protocol before any asset movement occurs.
