Today we are proud to introduce @Arc, a new blockchain network purpose-built for stablecoin finance.

Arc is a step toward something I’ve been working on for years: building a real-world financial system that’s programmable, transparent, and global. One where the benefits of blockchains—openness, speed, and accessibility—can finally show up in everyday financial life.

But to understand why Arc feels so important to me, I want to share a bit of how I got here.

I studied finance at Cornell and spent time working at hedge funds and investment banks. That experience gave me a close look at how money moves through the global system. What stood out to me wasn’t the inefficiency – it was who the system served and who it left behind. The moment it became personal was when I tried sending money to my aunt in India. It should have been simple. Instead, it was slow, expensive, and unnecessarily complicated. That experience forced me to confront how outdated and exclusionary financial infrastructure really is.

It also pushed me into crypto. I joined a company building payment rails on the Bitcoin Lightning Network, trying to reimagine global payments from the ground up. The vision was bold, and I believed in it. But speed alone wasn’t enough. Without privacy, usability, and institutional trust, we were still far from something people could rely on at scale. That led me to start a company focused on privacy-preserving infrastructure. We wanted to build a foundation that made blockchains more secure, more human, and more capable of supporting real-world adoption.

That company was eventually acquired by @circle, where I’ve been working on how to bring stablecoin-based finance to individuals, developers, and institutions. That work has led to Arc. Arc is launching at a moment that feels uniquely aligned. The technology has matured. Institutions are leaning in. And the core building blocks—stablecoins, lending markets, and payment protocols—are in place. Arc isn’t trying to replace what came before. It’s here to complement it, with a purpose-built platform designed for performance, opt-in privacy and stablecoin-based financial use cases.

To me, Arc is a bet that now is the right time to lay the foundation for a more open, efficient, and inclusive financial system. A belief that stablecoins, paired with the right infrastructure, can open the door to a new category of finance, what we call StableFi. Not just for the crypto-native, but for people like my aunt who simply need a better way to move money and access financial tools.

Arc isn’t the finish line. It’s the starting point. I’m proud to be part of it, and I’m even more excited for what comes next. We’re still early, and there’s a lot to figure out. But the path feels clearer than ever. I’m excited to keep building, and even more excited to see what others create on Arc.
Introducing Arc, an open Layer-1 blockchain purpose-built for stablecoin finance.

From payments to FX to capital markets, Arc is the home for builders innovating with digital money and tokenized value on the internet.

Stablecoins have shown us what’s possible.

They’ve powered trillions in onchain transactions and unlocked a faster, more open financial system.

Arc is designed to provide an enterprise-grade foundation with the performance, reliability, and liquidity needed to scale stablecoin use cases worldwide.

Featuring:
✅ USDC as native gas
✅ Built-in FX engine
✅ Deterministic sub-second finality
✅ Opt-in privacy
✅ Full Circle platform integration

At its core is Malachite, a high-performance consensus engine developed by @informalinc that powers Arc with safety, liveness, and resilience at scale.

Arc expands the design space for stablecoins by uniting speed with certainty and delivering the native tooling needed to meet real-world business obligations.

Open and composable, Arc is designed to interoperate seamlessly with the broader multichain ecosystem.

Fully EVM-compatible, developers will be able to build on Arc using the same frameworks and tooling they know and trust.

Together, we’re laying the foundation to move stablecoin finance from early adoption to globally trusted infrastructure.

Arc will enter private testnet in the coming weeks, with public testnet expected this fall.

Progressive regulation will be enable portable user owned identity to exist for the first time. This will have insanely positive downstream effects for the adoption of all different types of digital assets and the emergence of net new venues and primitives.

🚨 LATEST: SEC Commissioner Hester Peirce says zero-knowledge proofs could verify compliance without collecting users’ personal data.

She warns current KYC/AML practices create “data haystacks.”

I kept coming back to this, particularly on multiplayer and commerce. In my opinion, agents won’t just shop in only existing markets, but rather make completely new ones possible.

Today humans are generally constrained by attention and coordination. Someone has to notice a need, express it, search, compare, negotiate and transact. If the potential value isn’t worth that effort, demand remains latent and assets or capacity remain “frozen.”

The internet lowered this threshold. Uber made idle cars and driver time marketable and Airbnb did the same for spare rooms. But each required a company to build a category-specific marketplace and aggregate enough liquidity to justify it.

Enormous amounts of economic activity never cross that threshold.

Agents can turn private preferences into persistent, executable policies. My agent might be authorized to buy a used EV below $50,000 if it meets my range, brand and condition requirements. Another agent might know its owner would sell theirs above $47,000, even though they never listed it. When those policies intersect, a market can form without either person shopping or selling.

That pattern could unlock markets for:

- Assets people would sell but never list
- Capacity that otherwise expires unused - appointments, freight space, hotel rooms or compute
- Outcomes that require several providers - an EV, financing, delivery and charger installation
- Supply that does not yet exist - a route or service that becomes viable once enough demand conditionally commits

At scale, agent mandates become an executable view of future demand. Suppliers can plan capacity, assemble new offerings or create supply against committed demand instead of inferring intent from clicks and ads.

The internet made certain assets marketable through category-specific platforms. Agents could make intent, assets and capacity programmable which allows markets to form on demand across the long tail of the economy.

Had many conversations this weekend re instinct / muse / consumer agents, key topics:

- Commerce is the obvious opportunity but unclear how to handle supply constrained markets (hot restaurant tables) vs demand constrained (people that need to fly to San Francisco tomorrow); auction + reverse auction is intuitive but doesn’t capture loyalty / spend / LTV / brand
- In a world where agents are the primary consumers what are their incentives? How do you market to them? What are their preferences and how distinct will they be from humans?
- Will the first breakout multiplayer pattern be agent to agent (instincts trusted friends) or agent inside human chats ?
- How do you design agents that increase social capital?
- What are the patterns for comparative advantage / agents hiring other agents and what are consumer preferences in terms of single vs many agent relationships?

If you’re building this space I’d love to hear from you / try your product .. I’m also curious to hear everyone’s views on the topics above.
