MetaMask Agent Wallet adds AI integrations and Bitrefill payments

MetaMask's Agent Wallet — its self-custodial wallet for AI agents — now plugs into Grok Bot, Cursor, and OpenAI's Codex, and gained a new real-world payments use case: agents can buy Bitrefill gift cards via the x402 HTTP payment protocol, letting users "pay for dinner" with agent-held crypto.

• Backed by MetaMask's transaction security, agents can manage wallets, swap and bridge tokens, trade perps on Hyperliquid, access Polymarket prediction markets, and earn onchain.
• Agent activity is bounded by user-set spend limits and an allowlist of supported protocols, with transaction simulation, threat scanning, and MEV protection on every transaction.
• Users set up the wallet through a command-line interface and skill packages, then delegate trading and payments to autonomous agents.
