New payment rails for AI agents: Polygon, Coinbase x402, Ripple MPP, Mesta, Kredete
Several providers announced agent payment infrastructure: Polygon is optimising for agent payments, Coinbase offers x402, Ripple has joined MPP, Mesta has launched agentic payments, and Kredete has acquired Gravv. One report says 99% of AI agent payments are settled in USDC (21–26 September 2026).
