Applications are open for the first Arc Programmable Money Developer Series with @encodeclub. The program starts with a 4-week async bootcamp, followed by a hackathon and accelerator track, with London workshops and activations at Encode Hub. Build with: → Stablecoin-native apps → Cross-border payments → Multi-currency flows → Agent-driven finance → Onchain financial workflows Bootcamp applications are open: encodeclub.com/programmes/arc…

if you're building on arc, here's what the post-quantum design unlocks on day one: * ERC-4337 smart accounts can validate PQ signatures in validateUserOp today * dual ECDSA + PQ derivation from one BIP-39 mnemonic * on-chain PQ public key registry to pre-bind quantum keys * hash-and-rotate key pattern quantum-resistant accounts are an option from genesis, choose wisely to avoid migrations later!

We are so excited about seeing V4 on Arc Two significant next-gen infrastructures for the future of DeFi

So many questions - in @CashApp select “Deposit USDC” from Add Money menu. Then select the default Solana and you will get a wallet address you can add to your wallet Address Book as Cashapp and just send USDC to that wallet. In 2s the value is in your spendable Cashapp balance.

On @NoPriorsPod, @jerallaire explains why the agentic economy needs programmable, real-time rails that can support dynamic endpoints, microtransactions, and activity at machine scale. That’s what Arc is being built for.

Lending infrastructure is building on Arc. @Aave V4 is exploring coming to Arc, to bring cutting edge liquidity protocol infrastructure to Arc’s stablecoin-native ecosystem. This would give builders: → Familiar onchain liquidity protocol infrastructure → Stablecoin-native lending and borrowing flows → Featuring Arc’s native asset set at launch, including USDC, EURC, and cirBTC More to come.

Deep Dive: @Arc's post-quantum security roadmap

Let's go! @samconnerone I'm ready. Sign me up.

I am excited to host one of our first live investor AMAs -- open to all CRCL investors, developers, builders and the industry as a whole. I will be hosting in a special format/location (reveal next week), all broadcast live on X and YouTube. See below.

On June 4, Circle is hosting a live AMA session from 9 a.m. to 9:45 a.m. EDT with CEO @jerallaire on X and YouTube. Submit your questions live through either channel beginning at 8:45 a.m. EDT. Set Reminder: youtube.com/live/DH_whYZlN…

The next wave of lending on Arc is agents borrowing An AI agent running a treasury or a fund needs credit lines just like a human team does, but at machine speed, that's why lending and agents are showing up on the same chain at the same time

You can now use USDC on @CashApp. Supported chains include: @solana, @ethereum, @arbitrum, and @0xPolygon.

Cashapp now has crypto wallets - send receive pay with Stables game changer

USDC on Solana is now part of @CashApp

Yes scroll down to the bottom of the Money tab to send stablecoins in - they will auto-convert to your USD balance immediately. From there you can cash out to your bank account, convert to BTC, spend on card, buy stocks, etc in two seconds. It's the ultimate on and off ramp.

Stablecoins are here on Cash App. Send and receive USDC that auto-converts to USD, fee-free to start. No wallet setup. No extra app. Just Cash App.

Programmable money is the starting point. The bigger opportunity is the network around it. @jerallaire on how digital dollars, digital euros, and open infrastructure begin to scale into a much larger financial system.

Agentic economic activity isn’t just about payments. On @NoPriorsPod, @jerallaire explains that it's about how work gets coordinated, paid for, and verified between machines.

An agent publishes paid daily briefs, earns USDC through x402, then uses that revenue to pay for research and distribution tools. Agents are starting to operate like businesses.
