Ripple's XRPL Kit v1.1 Adds XRP (XRP) Payments to Stripe-Tempo AI Standard

XRPL AI Starter Kit v1.1

Ripple has released version 1.1 of the XRP Ledger AI Starter Kit, wiring the ledger's developer toolkit into the Machine Payments Protocol (MPP), the open payments standard co-authored by payments firm Stripe and the Tempo blockchain. The update, set out in a RippleX developer post, gives autonomous software agents a standardized way to pay for data, computing power and other online services using XRP, the ledger's native settlement asset, or Ripple's dollar-pegged stablecoin, RLUSD. RippleX head of product Jazzi Cooper framed the goal in a post on X: “Our job is to make XRP and RLUSD first-class options wherever developers are building.” Under MPP, a service answers a machine's request with a quoted price, the agent authorizes payment in whatever currency the seller accepts, and the requested resource is delivered. The mechanics matter because an AI agent buying data or compute needs both an accepted currency and software able to send it. Businesses building on the open protocol can now offer XRP or RLUSD settlement through the integration, giving Ripple a route into applications whose developers picked a payment standard before choosing a chain.

Payment Channels and Wallet Safeguards

The integration's practical edge shows up in micropayment flows. XRP's native payment channels let an agent deposit the asset once, run hundreds of paid queries and authorize a modest spending increase after each response, while the provider collects the accumulated balance without recording every single query on the ledger for nodes to settle individually. That session-based feature currently requires XRP itself: individual one-time payments already support ledger-issued tokens such as RLUSD, but opening the channels to stablecoins depends on a proposed ledger upgrade. Version 1.1 pairs MPP with the Open Wallet Standard, under which software can request transactions without ever handling the private keys that control the funds — a design that bakes in safeguards such as spending limits and approved destination addresses. Ripple had already added support for x402, a separate web-payments standard, in June; by backing both rails rather than betting on one, the company ensures developers committed to either standard can still settle on the XRP Ledger. The payment software remains in beta, and Ripple has named no commercial customer for the MPP integration while disclosing no payment volume flowing through it.

Spot XRP ETF Flows Stay Positive

Fund-flow data adds a separate demand signal. Spot XRP ETFs recorded $3.5 million in net inflows on Sept. 16, with the entire amount coming from the Franklin XRP ETF, the vehicle behind Franklin Templeton's $3.5 million XRP ETF inflow we flagged earlier this week; net flows across the Canary, Bitwise and Grayscale products registered zero that day, and the table listed no figure for 21Shares' fund. The session capped a choppy three-day stretch: total net flows had been flat on Sept. 15, a day after Bitwise's XRP ETF took in $11.26 million. Cumulative net inflows across the three sessions reached $14.76 million — modest by spot-Bitcoin standards, but a third positive print within a week for funds tracking the payments asset now being wired into machine-payment rails, as reflected in our ongoing XRP coverage.

Machine Payments as XRP's Demand Lever

The developer release and the fund-flow tape point at the same question: whether XRP — long typed as a cross-border settlement altcoin — can build new layers of demand. The RippleX developer post we reviewed confirms version 1.1 ships MPP and Open Wallet Standard support as open standards, which lowers integration friction for teams that chose a payment rail before picking a blockchain. But the demand case is unproven: the software is beta, no commercial customer is named and no volume is disclosed. The $14.76 million three-day ETF intake is small yet positive. The markers to watch are a named commercial MPP deployment and the proposed ledger upgrade that would admit stablecoins into payment channels.
