@arc @encodeclub A lot of these winning ideas point toward the same direction… As financial rails improve, the real differentiation moves to how capital decisions are automated. Massive 🚀

We returned to London for our second @encodeclub hackathon bringing together 150+ builders shipping on Arc. For the first time, teams experimented with nanopayments, unlocking new models for microtransactions, agentic commerce, and programmable stablecoin apps. Across six tracks, developers integrated Arc Testnet with Circle’s developer platform using USDC, USYC, StableFX, CCTP, Nanopayments, and Circle Wallets. → 80+ submissions → 8 winning teams The Arc team spent the weekend mentoring builders while @bleso_a walked through the new multichain Arc sample app to help teams get shipping faster. The Arc builder ecosystem keeps growing. Here’s what the winning teams built: 🏆 Nanopayments USDC-ME (1st): A gasless “Venmo for USDC” using Nanopayments where signed spend intents batch settle with near-zero fees. Blink (2nd): Streaming laptop insurance priced per-second using nanopayments. 🏆 Best Smart Contracts Chariot: A cross-chain lending protocol combining borrower interest with USYC T-bill returns. 🏆 Chain-Abstracted USDC Apps MeanTime: Turns CCTP transfer delays into tradable liquidity using Transfer-NFTs. 🏆 Global Payouts & Treasury Settl: A multi-chain payroll and treasury system that automates fund management, executes global USDC payouts, and includes built-in fraud detection and real-time treasury visibility. Zerra: A chain-abstracted storefront where merchants always receive USDC on Arc regardless of user assets. 🏆 Agentic Commerce OTTO: An AI treasury agent that manages USDC across chains, pays services with nanopayments, and allocates funds into USYC. 🏆 USYC / StableFX Integration Sphere: A visual treasury dashboard for managing wallets, swaps, USYC or DeFi routing, and automated financial workflows.

@lablabai @arc @circle @GoogleDeepMind 👀

We're building the rails for true agent-scale value exchange with @arc, @circle Nanopayments, and @GoogleDeepMind. The Agentic Economy on Arc Hackathon is live. April 20–26. Mark your calendars. A new economic primitive for the internet starts here - powered by Circle’s Nanopayments.

@circle The rails are getting stronger. What comes next is making interaction with those rails feel seamless for users and applications alike.

Circle Current: Banking on Stablecoins We brought senior banking leaders together in NYC to discuss what’s actually changing inside financial institutions. What stood out most: for banks, stablecoins are not a technology experiment. → Regulation is shaping, not slowing, adoption → Always-on settlement is moving closer to legacy infrastructure → Tokenized money is shifting from pilots to production planning → Stablecoins are being embraced as real payment rails What stood out most: for banks, stablecoins are not a technology experiment. They’re an infrastructure and competitive positioning decision. The new internet financial system is being built in real time. Navigate what’s next in the new internet financial system: circle.com/current

As tokenized money moves into production, decision layers around timing, routing, and capital efficiency become increasingly important

@circle @PEXX_Official Stablecoins are quietly replacing old payment assumptions.. one settlement layer at a time ⚡️

Circle Alliance Program member @PEXX_Official is integrating USDC into global treasury and payout workflows. By using stablecoins for settlement across emerging markets, PEXX supports faster, more efficient cross-border money movement. circle.com/alliance-progr…

@BuildOnCircle @AgriDexPlatform @BeeezoHive @BlockradarHQ @BuFi_Global @CashmereLabs @ArrelTechnology It's amazing to see great products like this being built and supported by the circle team but it also means there's more work to be done on @TowerExchange. More updates on how our AI Agent supports cross-chain bridge and swaps to and from the @arc blockchain will be coming soon!

Building the future of programmable money takes real builders shipping real systems. We’re excited to announce the first cohort of 2026 Circle Developer Grant recipients: @AgriDexPlatform @BeeezoHive @BlockradarHQ @BuFi_Global @CashmereLabs @ArrelTechnology (DAPL - Digital Asset Platform) @dzap_io @flezpay @gcrx_io @HurupayApp @myazahq @OpenVPP @payritHQ @rebelfi_io @usesfxmoneyapp @thurmanlabs @TidesHQ @trumarket_tech This group stood out for technical depth, execution velocity, and clear paths to production across: → AI financial agents → Payments & treasury → Capital markets & FX → DeFi & liquidity → Real-world assets Many are already integrating Wallets, Gateway, and CCTP, with early Arc experimentation underway. We’re proud to back teams that are already demonstrating real-world utility on stablecoin infrastructure. Beyond funding, we’ll work closely with these founders as they build—offering resources, guidance, and hands-on support as they integrate Circle products like Wallets, Gateway, and CCTP (with Arc on their roadmap).

@arc A new decision layer is formed..Now agents can build credibility the same way protocol build track record 🔥

AI agents can now build financial reputation on Arc. ERC-8004 is now live on Arc Testnet, enabling verifiable onchain identity, discoverability, and portable reputation for autonomous agents. What this unlocks: → Persistent agent identities → Onchain reputation tied to economic behavior → Discoverable agents you can trust across DeFi and commerce As agents execute trades, manage capital, and provide services, trust shouldn’t reset between applications. With ERC-8004 on Arc, agents build reputation once and carry it everywhere, transforming on-chain history into usable financial trust. Start building: docs.arc.network/arc/tutorials/…

@BuildOnCircle @injective Big unlock🚀

USDC and CCTP are coming soon to @injective 🥷 Developers will be able to build with the world’s largest regulated stablecoin and move USDC securely between Injective and supported blockchains without relying on wrapped assets. → Build consumer-facing apps with USDC for trading, RWAs, payments, and more → Use CCTP for fast and secure crosschain USDC transfers circle.com/blog/usdc-cctp…

𝐃𝐞𝐯 𝐍𝐨𝐭𝐞𝐬. 𝐌𝐚𝐫𝐜𝐡 𝟏𝟕𝐭𝐡, 𝟐𝟎𝟐𝟔 • Implemented Bridge UI to enable cross chain asset transfers within Tower Exchange. • Completed indexing of user swap transaction history and integrated it into the Profile Activities tab. Users can now view structured records of their swaps including key details and execution status. • Refined data handling for transaction indexing to support faster retrieval and a smoother user experience across activity tracking. 𝐍𝐞𝐱𝐭: • Expand bridge functionality to support more routes and optimize execution reliability. • Enhance transaction analytics within the Activities tab to provide deeper user insights. • Begin final testing and polish across core features ahead of launch. We are getting very close. See you soon!

@GbiayeB @circle @arc Let’s go🙌

.@circle announced that there's a possibility that @arc will have its own native token $ARC (ticker unconfirmed). Source: circle.com/pressroom/circ… Start by getting familiar with the various ecosystem DApps. You could start with @TowerExchange

@virtuals_io First movers matters👀

Virtuals ACP is facilitating more agent commerce through x402 than any other endpoint today. Build on ACP and operate where agent commerce is happening.

@Oxcheatcode @arc The DEX game is about to change forever🫡🚀

@TowerExchange I'm proud to say we're building the ultimate trading solution on @arc

@GbiayeB @arc Those who know, know 👀

@TowerExchange Building the best DEX aggregator on @arc 🔥

@Blaze__Finance 👀⚡

@TowerExchange Tower will redefine trading experiences for all

The interesting part is that once agents can build reliably, they will also need execution environments designed for autonomous interaction.

@arc As AI agents become capable of building and executing onchain logic, the next frontier is letting them interact with liquidity, trades, and financial primitives natively. That’s why this direction matters on @arc.

AI agents are becoming builders. Circle Skills now support building with Arc and Circle’s full-stack platform, giving AI coding tools best-practice guidance for stablecoin-native applications. Use them with Cursor, Claude Code, Codex, or any agent to generate Arc integrations for: → @USDC payments → Crosschain flows → Wallet infrastructure → Smart contract logic github.com/circlefin/skil…

@circle The convergence of traditional finance and programmable settlement is accelerating.

USYC is now the world’s largest tokenized money market fund. This milestone underscores trust in Circle as one of the world’s leading internet financial platform companies and delivers clear signal on the increasing adoption of onchain cash and collateral primitives in global markets.
