Circle Match is now available to eligible Circle Mint customers.
Every hour, Circle Match brings institutional mint-and-redeem USDC demand together in an auction inside Mint.
When orders match, mints earn a rebate and redemptions clear at a price you set.
Same USDC flows. New economics.

Arc 🤝 @Aster_DEX
Aster now supports USDC collateral on Arc, with USDC-margined perpetual futures on BTC, ETH, and SOL now live.
For the first time, USDC is a trading and margin asset on Aster.

Arc 🤝 @extendedapp
Extended is now fully migrated and live on Arc.
USDC collateral. cirBTC as BTC collateral.
Now live on Arc.

Another vulnerability few are talking about: I found my Claude Code exposing personal data in http headers because the sites it curled politely asked agents to identify their users 😊
Epistemic cybersecurity is the hot new category for 2027.

Extended now settles on @arc.
The migration of $120 million in TVL is complete, with open positions and orders carried across. Trading continued throughout the process.
What this means for our users:
• Faster deposits and withdrawals, leveraging Arc’s sub-second finality.
• Native USDC transfers through Circle’s CCTP.
• cirBTC is now the BTC collateral asset.
Deposits and withdrawals are open again.

Extended moves to @arc on Thursday.
Settlement migrates from Starknet to Arc on October 22 at 13:00 UTC. The migration is planned with no interruption to trading. Positions can still be liquidated during this time, so top up margin beforehand. Transfers between sub-accounts stay open.
Most accounts need to do nothing. Your account, sub-accounts, positions, orders, history, points and keys carry across unchanged. USDC migrates as native USDC, ETH migrates 1:1 as wETH, and Vault (XVS) balances and withdrawal rights are preserved.
If you hold more than $1 of USDT or wBTC in any sub-account, you must act by 12:00 UTC on October 21:
- Authorise the conversion in-app. USDT converts to USDC and wBTC to cirBTC at 1:1 during the migration, with no swap fees. Extended credits a 0.50% premium.
- Or withdraw both assets.
If you miss the deadline, your whole account will be restricted for up to 30 minutes on October 21 while Extended cancels orders, closes positions in the affected sub-accounts at mark price with no fees, and returns your USDT and wBTC to your login wallet.
Deposits and withdrawals will be paused for up to 2 hours during the migration.

Circle paid roughly $819M to USDC distribution partners and transaction costs in the first half of 2026.
More than 150 partners participate in USDC’s economics, sharing in the growth they help drive.
Here’s how the model works: circle.com/blog/the-economic…
Cool milestone! Maintain a unified balance, and route USDC between apps across chains under 500 ms. Excellent work enabling this from our interop team!

Circle CCTP has crossed $100M in crosschain volume for supported non-USDC assets.
That includes cirBTC, EURC, and WETH, showing how CCTP is expanding beyond USDC to support more ways for value to move across supported chains.
More assets with the same trusted crosschain infrastructure.
You can build this UX in your app with a few lines of code using npmjs.com/package/@circle-fi…
I just bridged USDC from @solana to @arc mainnet

having flipped the NASDAQ's daily notional traded volume, we have reached out to @NasdaqExchange to discuss the potential implementation of 1000x leverage in order to improve their volumes...
Let’s go!
Arc 🤝 @extendedapp
Extended is moving settlement to Arc.
The perp DEX with $200B+ in lifetime volume brings onchain trading onto infrastructure with deterministic sub-second finality and gas paid in USDC.
USDC collateral. cirBTC as BTC collateral.
All on Arc.

Build crypto-backed borrowing into your app on Arc.
We open sourced a USDC Borrowing sample app using Borrow Kit.
It walks through the full flow: discover a market, size a loan, deposit cirBTC as collateral, borrow USDC, monitor health, repay, and close.
No custom smart contract code. No direct lending protocol integration to maintain.
Clone it and start building: github.com/circlefin/arc-usd…
