Core systems enabling money movement between consumers, merchants, banks, and fintechs — evolving toward 24/7 on-chain rails and AI-agent payment layers.

Key Points

  • Card networks: visa Intelligent Commerce (Agent Score, Agentic Directory, Large Transaction Model) + openai integration; mastercard stablecoin settlement
  • HTTP payment protocol: x402 — HTTP 402 stablecoin micropayments for APIs and agent services
  • MCP connectivity: @coinbase/payments-mcp, Robinhood Trading/Banking MCP servers
  • Stablecoin settlement: Visa ~$7B annualized run rate (March 2026); programmable bank deposits
  • Open banking: UK commercial variable recurring payments (uk-payments-initiative)

Agentic Layer (June 2026)

Three parallel stacks emerged within one week:

  1. Card/tokenized: Visa-OpenAI with spending limits and fraud AI
  2. Crypto/M2M: Coinbase x402 with isolated agent portfolios
  3. Brokerage: Robinhood MCP agent accounts
