Base, the Ethereum Layer-2 network developed by Coinbase, has launched a new developer toolkit designed to connect AI models directly with blockchain wallets and decentralized finance systems.
Called the Base Model Context Protocol (MCP), the framework enables conversational AI systems such as OpenAI’s ChatGPT and Anthropic’s Claude to perform blockchain-related actions through natural language interfaces.
Using the toolkit, AI agents can check wallet balances, review transaction histories, transfer digital assets, and execute token swaps across supported decentralized applications including Morpho, Moonwell, Uniswap, Aerodrome, Avantis, Bankr, and Virtuals.
According to Coinbase, the architecture is designed to maintain synchronization between AI-driven interactions and users’ native Base accounts, allowing portfolios, balances, and transaction histories to remain unified across interfaces.
To address security concerns, Base said AI agents cannot directly access private keys or autonomously execute transactions. Instead, the AI generates transaction proposals that users must manually approve through a separate wallet confirmation flow that includes balance simulations and transaction previews.
The launch is closely tied to Coinbase’s broader push into agentic AI payments and machine-to-machine commerce. The system is expected to accelerate adoption of x402, Coinbase’s payment standard for autonomous AI agents and micro-transactions.
