Agentic payments are live on Arc.

Our Facilitator Service gives x402 builders a hosted way to accept Circle-issued USDC on Arc, Base, and Polygon without running their own relayer or funding separate gas wallets.

You build the service. Agents pay for it.

[Jeremy Allaire @jerallaire]

Very impressed with Column Bank's execution.

[Circle @circle]

@coincircuitHQ Welcome to CAP!

[Circle @circle]

Column is adding USDC to its payments infrastructure.

Fintechs banking with @column can now access stablecoin payments alongside cards, wires, ACH, Swift, and RTP through a single API.

This is USDC becoming part of real financial infrastructure.

Circle CEO @jerallaire isn't fazed by the Senate's decision to block the CLARITY Act.

He believes regulators will keep moving crypto market structure forward, and Congress will eventually catch up with additional laws.

"The key thing is that a year ago The GENIUS Act, which makes digital dollars legal in the U.S. financial system, became federal law. So a lot of our work is done."

"CLARITY is about how trading venues get set up, clarifications around how DeFi is treated, etc. It's market structure."

"The agencies that regulate these things, like the CFTC, the SEC, even the bank regulators too, they're all just going to move forward and regulate it themselves."

"Eventually we'll get additional laws passed through Congress."

Wrapped BTC is only as strong as the collateral structure behind it.

For institutions, the real questions are reserve separation, rehypothecation, redemption, and verification.

cirBTC is designed to meet that standard with 1:1 BTC backing, segregated collateral, real-time onchain proof of reserves, and a neutral issuer model.

[Orthogonal (YC W26) @orthogonal_sh]

@arc mainnet is live. Orthogonal supports Nanopayments powered by @circle Gateway on Arc from day one.

Agents can now pay for API calls on Orthogonal using USDC nanopayments on Arc.

[Cycles @cyclesmoney]

Cycles Pay is now officially running on @arc mainnet.
This is the first application built on top of the Cycles protocol, a privacy-preserving clearing algorithm that finds loops of mutual debt and settles them without altering what each party is owed on net.

We already have a web app and a mobile app, and we’ve already added support for both businesses and individuals.

Perhaps more importantly, it has a combination of features no one else in the industry has built yet: private stablecoin payments, earn vaults, invoicing, expense splitting and AI assistants.

And we’re working on adding invoice financing, credit scores, balance lending, and rotating savings groups with the ultimate goal of becoming the first on-chain credit bureau to deliver credit scores based on real payment history and active payment obligations.

@arc is the foundation. We chose it because it is designed for payments with USDC as gas, sub-second finality, and reliable global infrastructure.

Tokenization could change how capital forms and moves onchain.

@chandhok discusses what that could mean for smaller businesses, internet native capital markets, and onchain credit.

[Circle @circle]

cirBTC is designed to help bring a blue-chip BTC collateral layer to onchain credit markets.

Bitcoin has the depth and liquidity to support onchain lending, but collateral quality depends on more than the asset underneath.

→ Reserve integrity
→ Segregated custody
→ Redemption path
→ Onchain verification
→ Issuer incentives

Well-defined collateral can support disciplined risk parameters, reliable liquidations, and deeper participation on both sides of a lending market.

EURC is now available on Upbit across KRW, BTC, and other markets, expanding access to Circle’s fully backed, MiCA-compliant euro stablecoin in South Korea.

[This Week in Fintech @twifintech]

We’re backstage at @thestablecon sitting down with the speakers as they come off stage. @unvested_ spoke with @ddisparte about whether the US needs a CBDC.

His answer? A US CBDC would be “against the American way of doing business.”

They discuss why stablecoins should remain privately issued, how regulation can provide the guardrails, and why clearer accounting standards could be an important step toward mainstream adoption.
