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.

another week, another Gateway explainer. our Gateway quickstarts now cover Circle Wallets and the permissionless option for both EVM and Solana. Gateway is wallet-agnostic, so you can choose what type of app experience you want your users to have. developers.circle.com/gateway/quicks…

Same-day payments for international contractors are now live in Gusto. Wise Account or USDC stablecoin - contractors pick what works for them. Employers pay the same way they always have.

We’re thrilled to announce that GCRx has been chosen as a Circle Grant recipient! @Circle is helping bring the global economy onchain with $USDC and a set of developer-first tools designed to make building with digital dollars easy, secure, and scalable. With Circle’s support, we’re excited to accelerate what we’re building—unlocking new possibilities through fast, cost-efficient, and interoperable onchain experiences.

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).

USDC & CCTP are now live on @MorphNetwork! Fully supported through Firefly Lab's Bridge Service! Seamless cross-chain @USDC transfers powered by @circle CCTP & @FireflyLabs Try it now: fireflylabs.app

Build AI agents with portable, verifiable financial reputation. ERC-8004 is now live on Arc Testnet, giving autonomous agents persistent onchain identity, discoverability, and reputation tied to real economic activity. What you can build: → Agent credit scoring for DeFi protocols → Reputation-gated marketplaces → Trust layers for autonomous trading systems As agents execute trades, manage capital, and provide services, their credibility shouldn’t reset across applications. With ERC-8004 on Arc, reputation becomes programmable infrastructure, usable across DeFi and commerce from day one. The quickstart walks through agent registration, reputation events, and validation using Circle developer-controlled wallets: docs.arc.network/arc/tutorials/…

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…

AI agents that can spend USDC. Autonomously. ClawRouter from BlockRunAI was a standout winner in the USDC OpenClaw Hackathon, pushing the boundaries of agentic commerce onchain. Join @samconnerone and Vicky Fu live on Mar 19 at 2PM ET for a deep dive into the winning build: → Per-agent USDC wallets → Autonomous model selection via local scoring → Pay-per-inference with signed USDC authorizations → How to run and extend it locally See how hackathon ideas turn into real, composable infrastructure for the agent economy.

Supporting multiple chains means managing USDC balances across all of them. In this guide, @hj_chen walks through how to consolidate crosschain USDC on @arc: → Bridge USDC via CCTP Fast Transfer → Consolidate into a unified EVM address → Deposit into Gateway → Execute near-instant crosschain payouts Fewer balances. Cleaner treasury logic. Read the full implementation: circle.com/blog/consolida…
