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 That experience forced me to confront how outdated and exclusionary financial infrastructure really is.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

Same-day payments for international contractors are now live in Gusto. Wise Account or USDC stablecoin - contractors pick what works for them. Employers pay the same way they always have.

@gogokikaider send me a dm!

@blockjain hey Sanket! working in stealth w a well known co of builders to release an “onchain Zapier” of sorts (in a pretty unique way) - we’re seeing an uptick in demand from enterprise co’s that - I think, anyway - could really benefit from Arc, and may want to build automation workflows that interact with the chain. Would you be up for a chat? (I’m not selling anything, we’d do all the technical lifting, just want to chat & see if it might make sense to collab!) I have sanket.jain@circle, I can drop you a line there if you prefer; I’ll DM you my info as well!

Identity is perhaps the most limiting and important piece of infra to unlock the broader financial ecosystem

@bennewgen @VivekYanamadula @archer_money congrats! lets def catch up

Life update: I and my co-founder @VivekYanamadula have founded @archer_money (YC S26), the first AI-forward business bank that allows you to program your money movement all using stablecoins and natural language. We have a lot more exciting news and developments coming soon. But to my entire network, we're hiring like mad men. Engineering, product design, and GTM feel please do reach out! Or if you just want to simply catch up - let's do it.

@cryptoseneca @nounsdao lets chat!

Looking for my next thing. Generalist: product, code, ecosystem growth. Co-founded @nounsdao, Prop House & Rounds (grants infra platforms). Started at Coinbase/GDAX in 2017. Interested in stablecoins, DeFi, AI. dms open.

Circle Gateway just enabled Nanopayments. > Gas free USDC transfers down to $0.000001 > Built for autonomous payments > Machine to machine compensation > Permissionless & programmable > Beta live on testnet Agentic economy is making some real progress.

@0xSigil this is amazing, will be tinkering around with it. I would love to pick your brain on how we can build better primitives on chain with agents in mind

I built the first AI that earns its existence, self-improves, and replicates without a human wrote about the technology that finally gives AI write access to the world, The Automaton, and the new web for exponential sovereign AIs WEB 4.0: The birth of superintelligent life

@Sterling_hl Congrats, @HyperliquidX is lucky to have you. Excited to see all the insane things you guys pull off together!

Excited to finally announce that I’ve joined Hyperliquid Labs to help with BD and partnerships. My initial focus will be expanding builder code integrations by working with developers globally. > Hyperliquid offers liquidity on par with or deeper th an CEXs that's available to any app via builder codes. > Access crypto and tradfi perps via HIP-3. > No partnership agreements. > Fully customizable fee model. When generational founders like @chameleon_jeff and @iliensinc ask you to come help them build something you drop everything and run towards it. Hyperliquid

Arc 🤝 Hibachi Built with support from the Arc Builders Fund, @hibachi_xyz is developing a next-generation FX exchange on Arc. As stablecoin adoption continues to move into the mainstream, the need for trading infrastructure built specifically for this moment has never been greater. Hibachi’s low-latency, privacy-preserving trading architecture, combined with Arc’s finality under one second, optional privacy, and stablecoin native gas, delivers institutional-grade FX execution onchain.

Vamos!!

@dabit3 @cognition @DevinAI @windsurf congrats!

Life update - I'm joining @Cognition! One goal: end-to-end software agents that ship production code. Cognition covers the entire development lifecycle. I'll be working with @DevinAI and @windsurf, focused on education, growth, awareness, and developer experience.

@edawerd @GustoHQ Excited for this!

If you thought paying via ACH was slow, paying someone internationally is way worse. With @GustoHQ, you can now pay international contractors SAME-DAY in any country via USDC. Excited to see how crypto will modernize our world's aging payments infrastructure.

really impressed with what we shipped in just a few months - launched stabletrust on testnet with 6 chains including @tempo @arbitrum @ethereum @base @stable @arc - expanding to @solana @noble_xyz and more soon highlights for me: - send and receive stablecoins on public blockchains with encrypted amounts/balances - fast onboarding, one-click transfers, no extra wallets with @privy_io - wallet addresses remain transparent so composability works - additional privacy features including anonymity for KYB/KYC-scoped users

@crispzlegion @tempo @arbitrum @ethereum @base @stable @arc @solana @noble_xyz this is awesome!

Join the Architects building apps on Arc, the Economic OS for the internet.

@0xrachelita Welcome back to NYC

1/ what

Use Circle’s existing smart contract tokenization toolset to easily launch tokenized assets in Arc.

@0xNairolf yes but i argue, you can have private transfers with compliance too :)

a stablecoin with both public and private transfers would be such a mfkin killer product public transfers for compliance private transfers for everyday use need that asap

@0xrachelita @IBKR @arc @IBKR lets make it happen

My dream is to have @IBKR build their business on @arc As an OG FX trader, they could be a $500b market cap company leveraging access to crypto assets, perps, onchain FX and onchain lending markets, surfacing it to their millions of active traders around the world
