Circle Developer

Bridge Kit now supports @Arc Testnet! Bridge Kit makes it easy to build crosschain experiences with @USDC and CCTP V2 in under ten lines of code: → Intuitive SDK methods → Built-in monetization support → Flexible setup → Step-by-step tutorials Get started with Bridge Kit: developers.circle.com/bridge-kit Learn more about Arc Testnet: docs.arc.network

Movement $USDCx availability continues to grow and is now supported by @kucoincom!

Crosschain swaps are now available in Swap Kit. @TxnSheng covers how developers can swap tokens across blockchains in one method call, using the same type-safe interface for same-chain and crosschain flows. Instead of stitching together separate swap, routing, and crosschain transfer logic, builders can use one swap method to define: → Source chain → Token in / token out → Amount → Destination chain → Recipient wallet

🇻🇳Chào anh em chúc anh em tuần mới vui vẻ và tràn đầy năng lượng Video recap lại @arc Meetup đầu tiên tại Việt Nam 🇻🇳 > Rất vui khi được gặp mặt, chia sẻ và kết nối với anh em và cũng cảm ơn những chia sẻ. > Cũng rất vui sau meetup có rất nhièu anh em nhận mail trở thành kiến trúc sư tier1. > Anh em điểm danh nào @Arcvnbuilders

Great DX update. Devs and agents can now import USDC, EURC, USYC, and cirBTC directly from viem/tokens, with no token registry required. Get started with USDC: developers.circle.com/stablecoins/qu…

Stablecoin trust starts with redemption. At the @BIS_org Annual General Meeting, @ddisparte explained why Circle treats issuing USDC as a privilege and redeeming it as a right. That principle now supports payments to more than 180 countries.

I'm here in Cape Town with my @Circle fam shooting Culture of Currency, meeting some incredible entrepeneurs like Sindz Mavundla @KhaltshaCycles @Sikiskoffee and seeing how the future's getting built. #cultureofcurrency

“The only limit on smart contracts was who could write them, and generative AI just removed it.” At @VivaTech, @jerallaire discussed how AI can turn economic intent into executable code, expanding what developers and builders can create onchain.

Agents should be able to operate within clear spending limits. Research today's top developments in AI. Use up to $5 in USDC for any API calls needed and stay within budget. Powered by Circle Agent Stack: agents.circle.com

Gateway just had its biggest week ever for mint and transfer volume. Total lifetime volume is now over $4.5B as developers and businesses use Gateway for faster, simpler USDC movement across chains.

1 week, 5 events, the @circle & @arc team was in Istanbul! 🇹🇷 We brought together people from very different backgrounds across 5 events. Builders, founders, leading banks, exchanges, fintechs, NGOs, investors and everyone curious about the ecosystem all met in Istanbul in a single week. I'll be sharing the details of each event over the coming days. For now, a few frames from the amazing team behind this week 🙂 A huge thank you to everyone who attended, and a special shoutout to the people who made the week possible!

Most of the stablecoin conversation skips the most important part, which is the network underneath. At the @BIS_org, @ddisparte compared it to designing a high speed train system while ignoring where the trains actually stop. The rails decide who gets to ride.

Thanks @peterschroederr - years have passed, laws have since been enacted, but the mission remains unchanged.

We’re moving from a world where you work for money, to a world where money works for you. Circle Agent Stack and USDC are at the heart of the agentic economy.

Ended a whirlwind week with several packed days in Istanbul. Press conference, government meetings, developer events and boot camps, and an evening with an incredibly vibrant ecosystem here. Energy here is some of the best in the world right now.

Last week, the DevRel team had the opportunity to visit Türkiye, to share about what we've been building with @arc, and our developer toolings such as the Circle Agent Stack and App Kits, but more importantly, to connect with builders on the ground. We've held 5 events over the course of 3 days: an Arc community meetup, a main event headlined by our CEO, @jerallaire, 2 developer workshops (with a surprise drop-in sharing and Q&A session by Jeremy), and a happy hour to close. Hundreds came through -- from founders, builders, and developers at the meetup and workshops, to C-level leaders from banks, institutions, and exchanges at the main event, with some flying into Istanbul from across the country just for the events. You don't get that kind of intensity unless a market is serious about building onchain. And Türkiye is by far one of the markets that feels most alive onchain right now. What struck me the most was that many builders showed up knowing about our tech stack. They weren't there just for affirmation, but to connect, go deeper and to build, with many already building on Arc Testnet. Across all the conversations I've had, if there was one constant, it was stablecoins -- not as a trade, but as everyday money. People here talked about how even their moms and grandmothers buy stablecoins and other digital assets. That kind of everyday adoption is rare anywhere else. We came to teach, and left having learned just as much. So thank you to everyone who showed up -- the Architects, the founders, the builders. Türkiye, this was chapter one 🇹🇷 Huge shoutout to @ezgiyaltay, @hj_chen, and the rest of the Circle team for making it all happen!
