More assets. Familiar tools. One integrated stack. CCTP and Bridge Kit, now support expanded multi-asset workflows, with Arc as a Day 1 destination for USDC, EURC, and cirBTC on supported routes.

An agent can research market sentiment, pay for the services it needs, create a brief, and deliver the update by phone. That is the shift Circle Agent Stack is built to support: agents that complete workflows, not just generate text.

I wrote more about the process on our forums on @Arc house community.arc.io/home/clubs/…

Social verification doesn't need to be slow or expensive. By Using @Circle's Agent Marketplace, I was able to run near instant account verification across thousands of X community accounts for under 20 USDC. agents.circle.com/services/t…

RT @arc: Offer your users onchain USDC earn experiences without writing smart contract code. Start building with Earn Kit: t.co/zS…

This user experience of moving money from one wallet to another wallet will only continue to improve. Frictionless money movement is already here.

Creating the wallet is the easy part. The part that actually kills conversion: getting money out of the bank an onchain (without getting mogged by fees), paying gas, and finishing one real transaction. @GetOnramper says up to half of fiat-to-crypto swaps still fail after KYC. That’s a lot of people who already said yes and then bounced. 1Shot teamed up with @circle to fix this.

WELCOME TO ARC ACCELERATION SEASON! These are the startups selected for the six-week Acceleration Season with @Arc. The program starts next Monday, and on November 5 they'll take the stage at Demo Day to show what they built. Congratulations to @UpscaleTrade, @MiDatoPay, @DAMM_Capital, @cyclesmoney, @terralima_ag, @LendoorProtocol, @TrustlessWork, @fluuix, @Aquazero0, @ai_dentity, @aomi_labs, @Bitjuapp, @BuFi_Global, Slippay, DApps Factory and Masterlaw®.

GetLiquid says the $3.5T private credit market still runs on spreadsheets. Chris Miller & Mark Napolitano of @getliquid_io on how they're bringing real estate lending with Arc.

x402 is becoming a building block for agentic commerce. @organ_danny co-authored the x402 whitepaper and is working on products to grow the agentic economy at @circle. He'll be joining us at Agentic Zero. We can't wait to hear more!

Interop on Arc is here. A new integrated stack for builders creating crosschain applications on Arc. Build with: → Move supported Circle-issued assets natively with CCTP → Bring third-party tokens crosschain through wrapping → Launch new multichain assets with CTS → Manage unified crosschain balances with Gateway Crosschain liquidity, without the complexity. arc.io/blog/introducing-inte…

3,968 registrations. 1,239 projects. 12 finalists. Meet the hackathon finalist teams that are heading into the @arc Programmable Money Accelerator! Eight weeks of workshops, 1:1s with the Encode team and a Demo Day in front of investors in November. Kicks off today at 4pm! Find out more👇 encodeclub.com/programmes/ar…

Agents do not browse like humans. They need service details in a format they can act on: → What the service does → What it costs → How to call it → How to pay → What comes back Machine-readable discovery is one of the foundations of the agentic economy.

Congrats to @arc on the mainnet launch! Arc is now on Allnodes with full & archive nodes, plus FREE RPC endpoints & snapshots on PublicNode. The Economic OS for the internet is open to everyone here arc.publicnode.com

Wirex today is increasingly an infrastructure company. The retail business gave us years of experience operating cards, accounts, payments, scheme connectivity and compliance ourselves. The shift was to take that operating stack and make it available to other companies building financial products. We launched the infrastructure business in November 2025. In 131 days, it became the fastest stablecoin payment infrastructure to reach $1B in annualised onchain volume. That run rate has since passed $2B. Partners can now build with cards, accounts, payouts, settlement and other financial products through one integration, with an average signed-to-live timeline of 44 days. That is the direction of the business now. We are building the infrastructure other companies use to bring stablecoin-powered financial products to market. In this conversation with @samconnerone, Community Lead Developer at @circle and @arc, our Group CEO and Co-Founder @matveevp explains how Wirex moved from retail into infrastructure and what that focus looks like today.

Gas paid in @USDC, fees around a cent, finality in under a second, and full EVM compatibility so your Solidity carries over. Everything developers need to know about @Arc before Sept 16:

How do AI agents discover and pay for services? Two layers matter: → A marketplace where services are listed → A payment layer where agents can pay and receive the result With Circle Agent Stack, agents can discover, pay for, and use services in one workflow.

Eco Smart Deposits for @Circle Gateway are live. Circle Gateway users can deposit from any Eco-supported chain and see funds in seconds. Gasless, non-custodial, and low, predictable costs. One function call, no multi-chain plumbing to build.
