Coinbase CEO Brian Armstrong said the exchange is building a financial account for AI agents, while Coinbase for Agents already connects supported AI applications with Coinbase Advanced Trade. Users can place funds in isolated portfolios, restrict permissions and allow agents to trade supported cryptocurrencies, derivatives and equities. The service supports spot trading across more than 900 cryptocurrency pairs, eligible U.S. futures, S&P 500 equities, portfolio monitoring and USDC-dollar conversions, subject to eligibility and regulatory restrictions. Coinbase says x402 payments for agent-consumed research, data services and computing are coming soon. The company warns that agents can misinterpret instructions, and users remain responsible for authorized trades, transfers and account changes. The initiative followed a question from Ruby on Rails creator David Heinemeier Hansson about an "agentic bank." Coinbase has not provided a launch date, product name, fee structure or regulatory details for the broader financial account, which remains a stated direction rather than a confirmed banking product.
