Every era of economic transformation has begun the same way: with infrastructure that seems niche – until it isn’t.Early irrigation systems unlocked the first cities. Early railroad networks rewired entire economies. The internet’s core protocols, TCP/IP, turned slow and siloed information networks into a single, global system of communication. And the Cloud turned idle servers into the foundation of the digital economy.We don’t remember them for how they started. We remember them for how they scaled. Because in effect, what once looked like niche experiments became the backbone of global markets.Stablecoins are next. Welcome to the age of the stablecoin layer: an open, programmable foundation for global money movement.Just last year, stablecoins lacked clear regulation and were dismissed by much of the financial establishment. Fast forward a matter of months, and the U.S. Congress has passed the GENIUS Act, creating the country’s first federal framework for stablecoins and defining them explicitly as payment instruments. Major banks and card networks have entered this space. Early-movers like Circle have made their Wall Street debut. And fintech leaders from Stripe to Shopify are embracing stablecoins to power faster, cheaper, always-on transactions.These aren’t isolated milestones. They’re early signs that stablecoins are on track to become core infrastructure, just like AWS became the quiet engine of the cloud economy. Stablecoins represent a platform shift in payments. Just like prior platform shifts – mainframe computing to individual computers, desktop to mobile, and on-premises to cloud-based infrastructure – stablecoins will unlock a wave of innovation by modernizing financial infrastructure. This is the tipping point, but it’s also only the beginning, and too many people are still thinking far too small.To many, dollars are still shackled to outdated infrastructure like wire transfers and ACH. None of it is built for composability, automation, or machine-to-machine interaction as is required in the modern age. It’s a slow-motion relic holding back an interconnected, global economy that wants to move faster and include more people. Until we modernize the rails, we’re capping the true velocity of money – and with it, global economic potential.Stablecoins snap that bind. No bank holidays, no middlemen, no concept of business days or hours. Just global, cheap, and instantaneous settlement at scales of billions of dollars at a time. That transformation is as fundamental as turning mail into email.Stablecoins offer what legacy financial infrastructure simply can’t: instant settlement, borderless reach, low costs, and programmable design. They will disrupt more than any other crypto building block – rewriting payments, liquifying capital markets, and bringing the internet’s speed and interoperability to money itself.This shift goes well beyond payments between people. Stablecoins will also underpin the next phase of AI-native commerce as sovereign AI agents abandon legacy fiat systems in favor of decentralized money that flows freely across blockchain infrastructure. This will power automated treasury flows, agentic commerce, machine-to-machine transactions, and sovereign AI agent transactions.Money is getting an upgrade.The stablecoin layer isn’t just a new system, it’s a new substrate for the global economy. The velocity of money movement is positively correlated with economic growth. Stablecoins will unlock trillions in latent economic activity and help grow global GDP by full percentage points each year. And all of this activity will be AI-native.Yet for all the progress, the opportunity is still in its infancy. The GENIUS Act was a critical milestone, but it’s still one piece of legislation. And while the stablecoin market cap sits at over $280 billion today, the U.S. M2 money supply – the total amount of money circulating within the US economy – exceeds $20 trillion. That’s nearly a 100:1 gap.We’re still underselling how fast and forceful the shift to the stablecoin standard will be, and how quickly AI will accelerate it. Put simply, this summer marked only the soft launch of the stablecoin era. The infrastructure is in place, and the scale of what’s coming far exceeds the conversation today.This shift won’t be loud, and that’s by design. In a few years, no one will say they’re “using stablecoins,” just like nobody says they’re “using cloud computing” to store pictures of their kids. They’ll just use money. And stablecoins will be the infrastructure powering it all behind the scenes, moving billions across the globe in real time.The biggest winners in this transition will be the platforms operating behind the scenes: those who power the rails, provide liquidity, and earn our trust. Fintechs will use stablecoins for instant settlement and global reach. Governments – eventually, reluctantly – will integrate stablecoins into critical economic functions. AI agents will speak the language of stablecoins natively.This isn’t a bet on crypto hype. It’s a recognition that our financial system needs an upgrade, and stablecoins are the gateway. They’re not just a better form of money; they’re the onramp to the onchain economy. Once users hold stablecoins, they’re one step away from accessing a global, open, and programmable financial system. That’s why the stablecoin layer isn’t just the most important sector in crypto – it’s the foundation for the future of digital currency.
