Coinbase’s Base launches tool for AI to use crypto wallets on May 26, 2026
Coinbase Global’s Ethereum Layer 2 network, Base, launched a new infrastructure tool on May 26, 2026, called Base MCP (Model Context Protocol). This development allows artificial intelligence agents to directly interact with crypto wallets and decentralized finance (DeFi) applications through conversational prompts. By connecting a Base Account to AI clients, users can manage on-chain assets without navigating traditional, manual interfaces.
The system utilizes the Model Context Protocol (MCP), an open standard formalized by Anthropic in 2024. This protocol serves as a bridge, enabling AI models like ChatGPT and Claude to securely interface with external applications on the Base network. As Brian Armstrong warns finance must move on-chain to stay relevant, this tool represents a push toward an “agentic” economy where machines handle financial logic.
Base development teams stated that the launch is a “first step toward making the onchain economy easier to use via AI.” The goal is to prevent users from needing to parse protocol interfaces or jump between various apps. Instead, an AI agent can understand a plain-language request, such as a token swap, and prepare the necessary blockchain actions for the user.
Infrastructure for AI-controlled crypto wallets
Base MCP functions by providing AI clients with the “context” necessary to understand the state of a user’s wallet. Without this infrastructure, standard AI models cannot natively see blockchain balances or history. The tool is currently compatible with several major AI clients, including Anthropic’s Claude, OpenAI’s ChatGPT, and coding assistants like Cursor and Codex.
Through these interfaces, agents can perform a variety of crypto tasks. These include checking account balances, reviewing transaction histories, and signing messages. The system also supports more technical operations, such as executing batched contract calls, which allow for multiple actions to occur within a single blockchain transaction. This level of automation is becoming a priority as AI and quantum tech divert capital into increasingly sophisticated digital asset strategies.
Agent-to-machine payment capabilities
A core component of this infrastructure is the x402 protocol, which Coinbase originally launched in May 2025. This protocol acts as an agentic AI payment standard, enabling machine-to-machine payments directly on-chain. By embedding stablecoin payments into standard internet requests, x402 allows for seamless value transfer between autonomous systems.
The x402 protocol has seen significant adoption since its debut, processing more than 50 million transactions as of February 2026. Data indicates it processed approximately $1.1 million in volume over a recent three-month period. Unlike traditional payment gateways, this protocol is designed specifically for automated agents to process payments via a decentralized framework on the Base network.
Integration with DeFi protocols and exchanges
At launch, Base MCP is already integrated with several prominent decentralized finance protocols. These partnerships ensure that AI agents have access to liquidity and lending markets from day one. Users can direct their agents to interact with these platforms to swap assets or manage yield-generating positions through simple dialogue.
The initial list of integrated protocols includes:
- Decentralized Exchanges: Uniswap and Aerodrome.
- Lending Platforms: Morpho and Moonwell.
- Trading and Infrastructure: Avantis, Bankr, and Virtuals.
These integrations provide a comprehensive ecosystem for AI-driven financial maneuvers. The availability of deep liquidity through Uniswap and Aerodrome is essential for agents executing complex swaps. Recent activity in the sector, such as when near protocol and hyperliquid crypto tokens surged, highlights the growing market interest in high-speed, automated decentralized infrastructure.
Security and user control in automated finance
While the Base MCP allows AI agents to prepare and navigate the ecosystem, Coinbase has maintained a framework that prioritizes user authority. AI agents can propose transactions and check data, but they operate within the user’s Base Account permissions. This is designed to ensure that users retain control over how assets are moved while benefiting from the speed of AI automation.
The transition toward an AI-led interface reflects a broader trend in the crypto industry to reduce technical barriers. By moving away from complex wallet addresses and manual signing processes, Base aims to make specialized financial interactions accessible to a wider audience. As the on-chain economy matures, Coinbase expects autonomous agents to play a central role in how users manage digital wealth.
