Money Is Becoming A Back-End Technology
September 14, 2026
Final Settlement's interview series, presented with Early Riders, features Crossmint co-founder and CTO Alfonso Gómez-Jordana making the case that money is becoming a back-end technology as AI agents pick payment rails and convert into stablecoins automatically. Onramp covers the conversation as part of its ongoing look at how AI, stablecoins, and bitcoin intersect, including whether bitcoin remains the neutral settlement asset once agents are transacting directly.
Liam sits down with Alfonso Gómez-Jordana, co-founder and CTO of Crossmint, who built Google's "I'm not a robot" captcha as an intern and now builds the payment rails those bots use. His argument is that money is becoming a back-end technology: agents will hold the card, pick the rail, convert into stablecoins when an endpoint demands it, and inside of ten years most people will stop looking at prices or approving transactions at all. They get into why MoneyGram is replacing its core with stablecoins and finally monetizing float it never touched, why standing up stablecoin acceptance is now easier than getting a Stripe account, what breaks when a prompt-injected agent is spending money that is not its own, and whether bitcoin stays the neutral settlement asset once data centers find something better to mine.

Frequently Asked Questions
What does Alfonso Gómez-Jordana mean by money becoming a back-end technology?
Gómez-Jordana, co-founder and CTO of Crossmint, argues that AI agents will increasingly hold the card, choose the payment rail, and convert into stablecoins whenever an endpoint requires it, so people stop looking at prices or approving transactions directly (06:12).
Why is MoneyGram replacing its core with stablecoins, according to the episode?
The episode explains that MoneyGram is rebuilding on stablecoin rails to finally monetize float it previously never touched, one of several examples the hosts cite of legacy payment firms adopting stablecoin infrastructure (09:50).
Does the episode say bitcoin will stay the neutral settlement asset?
The conversation raises the open question of whether bitcoin remains the neutral settlement asset once data centers find alternative resources to mine, without asserting a definitive outcome (34:05-38:27).
What risk does the episode flag with AI agents spending money?
The hosts discuss the principal-agent problem created when a prompt-injected AI agent spends money that isn't its own, a security risk raised as AI agents gain more autonomous purchasing power (17:59).
