Arc makes your assets interoperable

Arc makes your assets private

And now Arc makes your assets post quantum secure

Proud of our cracked cryptographers

[Jeremy Allaire - jerallaire.arc @jerallaire]

Arc will be one of the very first blockchain networks in the world with PQ features at Day 1 on mainnet. Read our full Post-Quantum roadmap.

[Jeremy Allaire - jerallaire.arc @jerallaire]

Arc will deliver magical experiences where crypto fades into the background and users are delighted with just using money in powerful new ways.

[Rachel Mayer @0xrachelita]

I thought I was obsessed with stablecoins until I met @SamBroner and he took it to a new level. Congrats on your launch! Better money indeed

Wen Arc?

[Peter Schroeder @peterschroederr]

In March alone, @USDC processed over a billion unique transactions.

This is the first time a stablecoin has crossed the billion-transaction mark in a single month.

[Jeremy Allaire - jerallaire.arc @jerallaire]

Arc is ready for agents coordinating and executing jobs and providing the optimal medium of exchange. ER -8183 now live on Arc Testnet.

The same stablecoin can produce very different outcomes for banks depending on the rails behind it.

That’s because bank adoption is shaped not just by the asset itself, but by capital treatment, governance, operational resilience, and settlement finality.

@Arc is designed to make that infrastructure clearer:
→ Known validators
→ Deterministic finality
→ Governance controls

A more legible path for banks evaluating how to scale USDC and EURC in regulated financial markets.

Circle has been named one of Fast Company’s 2026 World’s Most Innovative Companies.

[Kash Razzaghi @KashRazzaghi]

Grateful to the team at @Mastercard for the opportunity to share my background and why I’m so excited about the future of stablecoins

[Jeremy Allaire - jerallaire.arc @jerallaire]

We’re eating our own dog food.

We’ve begun using our own platform to settle inter-company settlements — $68M across 8 entities. Under 30 minutes. 24/7.

Our Treasury team did this with USDC and Circle Mint — replacing fiat wires that take 1-3 days with always-on, near-instant settlement. Full controls. Full auditability. 90% of transfer pricing done in a single day.

This is what the internet financial system looks like in practice. Not theory — operations.

With updates to Circle Mint coming online, this is becoming a possibility for any business.

Circle Nanopayments is now available for testing and integration for AI Agents and Developers.

[Jeremy Allaire - jerallaire.arc @jerallaire]

One of the most common questions I got last week was about how other countries, markets and currencies were reacting to and engaging with stablecoins, and Circle's role in this. In short, we are leaning in hard on helping quality stablecoins launch, and building blockchain, interoparability, liquidity and trading market solutions to help build the foundations necessary for real commerce and finance to flow around the world. StableFX and our Partner Stables program continues to progress. More to come.

[Circle @circle]

As billions of AI agents enter the global economy, the financial system must operate at internet speed and scale.

At @wef, @jerallaire on why stablecoins are the only infrastructure built for that future.

[Dante Disparte @ddisparte]

Nothing worth doing is worth doing alone. To our @circle colleagues, stakeholders, customers, and builders, thanks for making 2025 an exceptional year. Onwards.

build the next era of the internet economy on Arc

[Jeremy Allaire - jerallaire.arc @jerallaire]

Exciting milestone today as @jpmorgan successfully arranged a US Commercial Paper issuance onchain for @galaxydigital, with the issuance and redemption proceeds entirely paid in USDC, representing another market first for the USCP market.

[Circle @circle]

Arc Public Testnet is live.

@Arc is an open Layer-1 blockchain designed to serve as the Economic OS for the internet, uniting programmable money and onchain innovation with real-world economic activity.

→ Lending and financial services
→ Capital markets
→ Tokenized asset issuance
→ Stablecoin settlement worldwide

With deterministic sub-second finality, stablecoins as native gas, and opt-in configurable privacy, Arc is purpose-built to meet the needs of the global financial system.

It’s built for a world where:

→ Financial apps are as accessible as email
→ Dollars, euros, pesos, and other fiat currencies move instantly
→ Private transactions that support compliance happen at scale
→ AI agents transact and coordinate commercial activity autonomously

Arc testnet is already seeing participation from leading companies across capital markets, global payments and technology platforms, and full-stack developer infrastructure providers.

Guided by Circle’s vision of making money truly open and programmable, Arc is public internet infrastructure that invites everyone to build, coordinate, and transact onchain.
