Summary

MoonPay's Halsey Huth says the Sodot deal gave Paybox the non-custodial vault design it needed to let AI agents move money inside Claude, ChatGPT and Grok.

MoonPay built its AI agent commerce product, Paybox, on technology from its acquisition of Sodot, according to Halsey Huth, the company's head of ecosystems and strategic partnerships. Speaking on Stabledash Live, Huth said the deal let MoonPay build a "very unique kinda non custodial cloud secure vault architecture." Paybox is now live in Claude, ChatGPT and, since this week, Grok.

What Paybox does

Huth says the MoonPay services users already know, including on-ramps, off-ramps, virtual accounts and swaps, sit natively inside Paybox. The wallet is non-custodial, he says, and users can send part of their payroll into it, through payroll providers that MoonPay's enterprise side helps power.

MoonPay picked Claude, ChatGPT and Grok because they are "the three most popular agentic surfaces" with the largest user bases, Huth says. He adds that launching Paybox got some of MoonPay's crypto users to start using Claude and ChatGPT for the first time.

“I will say curiosity is probably the most helpful thing for everyone that cares about tinkering in our space right now... And then also everyone now needs to be thoughtful of if we're going to launch something, How is an agent going to be able to use it? So I think with those two pieces, be curious and be agent ready.”

Verification as a selling point

Huth argues that MoonPay's KYC and KYB layers let it confirm that the people using its services and APIs are verified MoonPay users. He says on-chain metrics alone do not always give that level of detail. He also says Paybox has been live for a number of months and is seeing "real volume."

Bringing APIs to agents

Huth says he holds discovery sessions with anyone who will talk about agentic commerce. Many of these are proofs of concept, he says, but things are moving quickly. In his view the payment standard he calls x four zero two has been pivotal, since for many groups it is probably the only way to let agents consume their APIs. MoonPay's R&D team also worked with the Venice team on AI models, building its own version of Full Moon TV on the side.

Huth contrasts this with the NFT boom. With agents, he says, crypto is used not as a buzzword but "because it's what unlocks what we wanted to happen."

Huth's advice to builders is to "be curious and be agent ready." MoonPay appears to be following that advice itself. He says more is coming on the Grok and Grok bot side, and that toward the end of the month Paybox will become more open and available to developers around the world.

MoonPay, Grok, X, and Sodot come up most.
