Ripple’s XRP Ledger Adds Support for Stripe and Tempo’s AI Payment Standard

Ripple’s developer arm RippleX released version 1.1 of the XRP Ledger AI Starter Kit on 15 September, adding support for two open standards that let artificial intelligence agents hold and spend XRP without custom key handling.

The update makes the XRP Ledger a settlement rail for the Machine Payment Protocol, an HTTP-native payments standard co-authored by Tempo and Stripe, and brings the chain into the Open Wallet Standard, according to RippleX’s announcement.

Two open standards for agent payments The Machine Payment Protocol, or MPP, lets a service return an HTTP 402 status with a price, the agent authorizes the payment, and the resource is delivered without an account or a checkout flow.

The Open Wallet Standard is a local-first, multi-chain wallet specification that keeps an agent’s keys in a single encrypted vault at ~/.ows/, decrypted only long enough to sign.
