According to the source, an X post on Oct 28, 2025 claims AI agents are moving closer to controlling crypto wallets via Coinbase’s Payments MCP, enabling wallet access and payments through an x402 protocol, raising immediate safety questions for market participants (source: X post dated Oct 28, 2025). For risk management, traders should note that robust permissioning, key custody, and policy-based transaction controls are critical, while delegated or agent-held signing keys increase the attack surface versus hardware wallets, multisig safes, and account abstraction safeguards documented by leading wallet standards (source: Coinbase Wallet developer documentation; source: Ethereum EIP-4337 specification; source: Safe (Gnosis Safe) documentation). From a trading perspective, treat the claim as unconfirmed until Coinbase publishes official documentation for Payments MCP and x402 detailing scopes, rate limits, and approval flows, and defer strategy assumptions about automated order flow or on-chain volumes driven by AI agents until such docs and SDKs are released (source: Coinbase developer documentation index as of Oct 2024; source: X post dated Oct 28, 2025). If production tooling ships, monitor for changes in transaction counts on Ethereum and Base, because higher competition for block space mechanically pressures gas fees during congestion and can influence ETH-denominated costs for on-chain execution (source: Ethereum gas and fee mechanics documentation; source: Base network documentation).
