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 That experience forced me to confront how outdated and exclusionary financial infrastructure really is.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.

@MrMinter_eth @0xrachelita No, gas abstraction is a user experience patch (someone still pays in the native tokens), our design implies that you can directly pay in the stablecoin

@0xrachelita isn't this just gas abstraction? I want to make sure I'm not missing anything here, I like learning about how other chains are trying to improve UX while gas abstraction is good and necessary, it's not exactly a novel concept lol

easy thing to miss in the ARC whitepaper protocol fees are paid in stablecoins. but they're converted to ARC at the protocol level before anything else happens. network usage = ARC demand, regardless of what you paid in

@0xDaedalus @0xrachelita It will be converted prior to reward distribution to stakers/burns. This conversion is happening with already existing ARC

@0xrachelita Is the protocol effectively minting ARC according to a conversion rate set by some dex / desk / oracle?

I gave an AI agent USDC to analyze my tweets and audit my X profile. Here’s how you can do the same.

Money is becoming programmable intent. Arc is the place where that intent is executed and settled. ARC token is how those global participants are coordinated.

ARC - Made in America

We shared our Q1 results today at @Circle, reflecting strong execution, market leadership and new platform launches.  A rapid convergence of AI platforms and onchain money are creating a new internet stack that will transform the global economic system. 

We’re seeing continued growth in USDC and record onchain transaction volume, which reached $21.5 trillion, up 263% year over year. We also launched our new Circle Agent Stack, saw significant growth in Circle Payments Network (CPN), and are preparing Arc Network for liftoff.  

More ahead.

@izqui9 @itstuyo This is one of the most seamless stable coin enabled cards I’ve used

cashback is dead. people surely love a 5 or 10% cashback. except it's only on random categories. except you have to maintain a $200k balance. except it's capped at $1,500 a quarter. except you have to keep referring people. optimizing cashback buries customers in fine print. when you make a purchase with @itstuyo, you might not have to pay for it at all. no fine print, no limits. you just tap your phone and instantly get a notification on whether you got charged or not. it's not cashback or a rebate, your balance literally doesn't go down. Buy Now Pay Maybe is the first thing we've shipped that pulls in people who never cared about crypto or stablecoins at scale. it sparks a level of curiosity and interest we just hadn't seen to date and we are excited to open it up to everyone. it's also incredibly fun and has already created so many fun anecdotes and interactions.

@IamBrandonHill @VoriHQ This is awesome, congrats

Grocery is a $1.5T domestic market — bigger than restaurants, bigger than hotels. But it's running on technology from the Reagan administration. We just raised a $22M Series B for @VoriHQ to make every supermarket in America autonomous.

@alive_eth Congrats!

Crypto cycles ebb and flow. Today, the fundamentals of the space are the strongest they’ve ever been, at a time when sentiment is near all-time lows. But the times when everyone seems to be turning their back on the space are the times when firms like ours can have the most impact. These are the times when supporting the founders who are doing the hard work to build the future matters the most. We have raised Crypto Fund V to partner with the founders who are growing the technology and values of the space from their OG cypherpunk roots to billions of people. It’s time to build 🚀

@This_Liss Well played

Had a Jane Street phone interview in 2016. "Price a 6-month forward on carrots." There's no carrot futures market, so I build one from scratch: seasonal harvest cycles, USDA demand elasticity, cold storage decay rates. One trader stops me. "Your storage cost function– you're modeling the carrot as dead inventory. Like grain in a silo." He asks me the metabolic respiration rate of a post-harvest carrot at 2°C. I estimate. "Your forward is overpriced by exactly that shrinkage. The underlying is consuming its own sugars. It's alive." Good correction. I adjust the model. I think I've recovered. Rejection email comes the next morning. Subject: "Ethical Review." My framework, they write, "relied on the severance of the root organism from its growth medium." The question about respiration was a test. The carrot was still alive and I'd built an entire derivatives structure on top of its death without questioning whether harvest was an acceptable act. I pull up the recruiter's original email. It doesn't say Jane Street. It says Jain Street– a non-violent quantitative commodities fund. The carrot was never supposed to be priced. It was supposed to be refused. I later learn the only candidate who passed that round was a former monk from Gujarat who sat in silence for eleven minutes and said, "I cannot put a price on life." He's now a partner.

Aave's stablecoin lending pools are at 100% utilization for ~3 days. Billions withdrawn. LPs can't exit. Borrow won't budge. This isn't the rsETH hack spreading. It's a governance-set rate ceiling like price control, a market failure coded in Solidity. 🧵 1/
