Arc Mainnet is live.
Arc launches as the Economic OS for the internet: an open platform for global markets, real-time value movement, tokenized assets, and agentic economic activity.
Arc is more than a blockchain.
It launches as a full-stack financial platform with assets, applications, interoperability, developer infrastructure, and Circle platform services live from day one.
Arc delivers USDC as native gas, deterministic sub-second finality, EVM compatibility, and institutional validators.
It integrates with Arc Studio, App Kits, Arc Portal, Circle Agent Stack, CCTP, Gateway, CPN, and StableFX.
A complete economic platform at genesis.
Arc launches with infrastructure for:
→ Agentic economic workflows
→ Lending and borrowing
→ Trading and liquidity
→ Onchain FX
→ Payments and settlement
→ Tokenized assets
→ Exchanges, wallets, custody, compliance, data, and developer tooling
190+ institutional and ecosystem builders are building across Arc.
Crosschain forwarding to @solana is now live for Circle CCTP and Bridge Kit.
Circle’s forwarding service automates destination-chain execution for crosschain USDC transfers, reducing operational complexity while improving speed and reliability.
→ Automate the final mile of crosschain transfers
→ Reduce end-to-end transfer time
→ Lower operational costs and third-party risk
→ Improve both developer and user experience
Supported for routes to @arbitrum, @avax, @base, @ethereum, HyperEVM from @HyperliquidX, @inkonchain, @LineaBuild, @monad_xyz, @optimism, @0xPolygon, @SeiNetwork, @solana, @SonicLabs, @unichain, and @world_chain_, with more blockchains expected.

Architected for stablecoin finance
Today, we’re unveiling @Arc: a new blockchain purpose-built for the era of stablecoin finance.
But first, my own story. I grew up in Venezuela, where money didn't hold its value. Overnight, hyperinflation could wipe out your savings. You saw the photos, suitcases of cash for paying at the supermarkets.
Amidst this chaos and uncertainty, crypto emerged as a lifeline. While much of the world saw Bitcoin and crypto as hype-prone assets with yet-determined utility, we recognized what they truly offered: freedom. Crypto was our way to preserve value. Our way to send money to loved ones. Our way to plan for our future and that of our families.
In short, crypto was our way to opt out of a system that no longer worked in our favor.
My experience in Venezuela shaped everything for me. It instilled in me an unwavering belief in the promise of crypto as a real alternative to insufficient financial infrastructure.
For the last eight years, I’ve worked at @Circle to bring that promise to life by growing USDC to be one of the most widely-adopted stablecoins in the world. Along the way, one thing was always clear: stablecoins alone were just the beginning. Partners seek a way out of the burden of the banking hours cutoff of available payment systems. Developers want a home for their stablecoin applications. Institutions feel the pain of volatile gas fees and lack of privacy controls beyond POCs.
We see the opportunity beyond just stablecoins, to stablecoin finance. An ecosystem purpose-built to offer developers, institutions, and builders the most impactful access to build with stablecoins.
We have always known the dawn of StableFi was inevitable, but the timing wasn’t right. Until now.
Arc is an open L1 blockchain built from the ground up to supercharge what stablecoins unlock:
✔️Fast, global payments
✔️Onchain FX and 24/7 settlement
✔️Institutional trading settlement without cumbersome intermediaries
✔️And whatever else tomorrow’s developers can envision
This is stablecoin finance — StableFi. Optimized for trust, usability, and scale, this is a world where money is designed to maintain stable value, flows seamlessly, and is accessible to anyone, anywhere. Whether you’re building a remittance service in Lagos, a savings app in Bogotá, or an FX trading platform in London … Arc is built for you.
Arc is made up of many stablecoin components and features we at Circle have envisioned over the years, now in one place:
✅ Built for USDC, and other USD and non-USD stablecoins
✅ EVM-compatible, with fast sub-second finality and low predictable fees
✅ Designed for opt-in privacy
✅ FX-engine for built in liquidity
For me, Arc is personal. For you, we’ve built it so you have a stablecoin home.
Even with all the innovation over the last decade, we are only just starting to experience the promise of stablecoin finance. It is the connective tissue between crypto’s ideals and the financial system our world needs.
Public testnet is coming this fall.
If you’re building StableFi, come build with us. It’s time.
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.

Klarna’s Buy Now Pay Later doesn’t work - it puts the burden on the user, creating millions of small non-performing loans.
So what works? Take a look at @somoscashea , flipping the model and charging businesses instead.
Show me the incentives and I’ll show you the outcome.
