Ripple’s stablecoin liquidity on the XRP Ledger has basically doubled in a month. That’s not a small jump — it’s a signal the company is serious about owning the infrastructure layer for AI-driven payments.
DeFiLlama tracked the XRPL stablecoin supply at roughly $770 million, up nearly 97% over the last 30 days. RWA.xyz puts the figure even higher, at $901.7 million, with Ripple’s own RLUSD stablecoin doing most of the heavy lifting. The gap between those two estimates is a bit murky — different methodologies, different snapshots — but either way, the trajectory is pretty clear. Ripple is closing in on a $1 billion milestone fast, and it’s doing it by betting hard on one specific narrative: AI agents that pay for things on their own, without a human clicking “approve.”
The XRPL AI Starter Kit and x402 Protocol
Ripple released the XRPL AI Starter Kit to make it easier for developers to build payment flows where AI agents act autonomously. The kit ships with an MCP server for querying XRPL documentation directly and new tutorials walking developers through agentic transactions step by step. It’s not just documentation cleanup — there’s actual tooling here.
The piece that ties it together is x402. That’s a payment standard built around HTTP’s 402 status code, which has sat mostly dormant for decades. Ripple’s version lets AI agents pay for services — API calls, model inference, data access — using either XRP or RLUSD. No human in the loop. The agent hits a paywall, the agent pays it, the agent moves on.
And the XRPL’s architecture is kind of purpose-built for this. Fast settlement, predictable fees, escrow, trust lines, multi-signing — these aren’t flashy features, but for an enterprise finance team trying to set guardrails on what an AI agent can spend and where, they matter a lot. Institutions can define transaction parameters in advance and let the software run within those limits. That’s the pitch, anyway.
Mastercard, Coinbase, Stripe — and the $182 Billion Target
Ripple isn’t doing this alone. Mastercard launched Agent Pay for Machines, a program aimed at machine-speed payments, and Ripple is among the participating companies. Getting RLUSD into that conversation matters — Mastercard brings institutional credibility and enterprise distribution that pure crypto plays can’t match on their own.
Coinbase, Stripe, and Cloudflare are also in the mix. Ripple is working with all three to push RLUSD and the XRPL into broader institutional discussions about automated financial infrastructure. That’s a deliberate move to get out of the crypto-native bubble and into conversations happening in corporate treasury departments and enterprise billing teams.
The number Ripple keeps coming back to is $182 billion. That’s the company’s estimate for the machine economy — the total market for autonomous AI systems handling financial transactions. It’s a big number, probably optimistic on the timeline, but the direction isn’t wrong. AI agents are already being deployed in workflows that touch payments, and the question of what stablecoin they use is genuinely open.
Right now, Base, Solana, and Polygon are leading on developer deployments for agentic use cases. Ripple’s not pretending to win that race. The bet is different: cede the retail and consumer layer, go hard on institutional and enterprise. Corporate treasury, automated vendor payments, compliance-heavy workflows where dollar-denominated settlement isn’t optional — that’s where Ripple thinks RLUSD can carve out real ground.
USDT and USDC dominate the broader stablecoin market by a wide margin. Ripple isn’t chasing their market share directly. RLUSD is a niche play, at least for now, aimed at buyers who need audit trails and built-in compliance tooling alongside their stablecoin. Whether that niche is big enough to matter is still unclear.
What’s clear is the infrastructure argument. XRPL settles transactions quickly and fees don’t spike unpredictably — two things that matter enormously when you’re designing a system where software is making thousands of micro-payments without human oversight. Traditional banking rails can’t do that cleanly. Most blockchain networks can, but they don’t come packaged with the institutional controls Ripple is leading with.
Ripple’s push into agentic payments is also a push away from the speculative image that’s followed crypto broadly. The company seems to want RLUSD associated with boring, reliable, enterprise-grade infrastructure — the kind of thing a CFO can explain to a board without mentioning price charts.
Whether the timing works out is another matter. The machine economy is probably still years from the scale Ripple is projecting. But the stablecoin supply nearly doubling in 30 days suggests someone, somewhere, is already moving money through XRPL at a pace that wasn’t happening before. RWA.xyz’s $901.7 million figure is the one to watch.

DeFiLlama tracked the supply at approximately $770 million, while RWA.xyz put it at $901.7 million, with Ripple’s RLUSD driving most of the recent growth after a nearly 97% increase over 30 days.
What is the x402 payment standard Ripple is using?
x402 is a payment standard built on HTTP’s 402 status code that lets AI agents autonomously pay for services like API calls and model inference using XRP or RLUSD, with no human approval required per transaction.
Which companies are working with Ripple on agentic payments?
Mastercard, Coinbase, Stripe, and Cloudflare are among the companies Ripple is working with to expand RLUSD and XRPL into institutional and enterprise payment discussions.
