Circle

Circle is discontinuing support for USDC and CCTP V1 (the legacy version) on the Noble blockchain as part of its broader transition to CCTP V2, Circle’s next-generation cross-chain protocol with faster finality and stronger security. Noble will not receive CCTP V2. Circle Mint customers, retail USDC holders, and non-Circle customers who hold USDC on Noble should migrate to another supported blockchain. New minting of USDC on Noble through Circle Mint will be disabled on October 13, 2026.

what you’ll learn Use Circle's keyless Discovery API to find x402 services that accept USDC across chains. Filter by category, chain, and price, then pay. An agent can pay for almost anything, but first it has to find it. As agents become economic actors, they need a way to discover a service, read its price, and check how to pay for it — without a human wiring up each integration by hand. A payable endpoint is not much use to an agent that cannot find it or verify its terms on its own.

what you’ll learn Developers can now quote and collect CCTP Fast Transfer fees upfront, enabling predictable transfer amounts and a smoother crosschain UX. Learn how CCTP's new upfront fee payment model lets developers quote and collect Fast Transfer fees before execution (in either the source chain's native gas token or USDC) so users always receive the full, expected USDC amount on the destination chain, with fees bundled into a single quote via the Quote API.

NEW YORK AND SINGAPORE,  SEPTEMBER 8, 2026 — Circle Internet Group, Inc. (NYSE: CRCL), the global financial technology firm and issuer of USDC today announced it has signed a definitive agreement to acquire Tazapay, a Singapore-headquartered B2B cross-border payments infrastructure company focused on serving payment service providers and financial institutions.

Heath Tarbert, President of Circle Internet Group, will testify before the U.S. House Financial Services Committee today on one of the most consequential questions in economic policy: whether the next generation of financial infrastructure will be built and governed under American law.

‍ CCTP, Circle’s infrastructure for multichain digital asset management and crosschain trust layer, is extending to additional Circle-issued assets. CCTP now supports native transfers of EURC, Circle’s euro-denominated stablecoin, running on the same production interoperability infrastructure that powers native USDC transfers today. With this addition, developers and blockchain ecosystems now have a single way to move USDC and EURC across supported chains.

Digital assets are subject to a number of risks, including price volatility. Transacting in digital assets could result in significant losses and may not be suitable for some consumers. Digital asset markets and exchanges are not regulated with the same controls or customer protections available with other forms of financial products and are subject to an evolving regulatory environment. Digital assets do not typically have legal tender status and are not covered by deposit protection insurance.

Quantum computing capability is climbing, and it is farther along than many people think. At the same time, cryptographers with the help of AI have found more efficient quantum attacks on the Bitcoin and Ethereum signature has fallen dramatically. The gap is closing from both sides, faster than many people expected. You can rent a quantum computer today. Amazon Braket offers access to multiple quantum hardware providers, including QuEra's neutral-atom machines — no specialized lab required.

We’re excited to announce that USDC, EURC, CCTP, and Bridge Kit are now available on Plasma. Plasma is an EVM-compatible, Layer-1 (L1) blockchain built for high-throughput stablecoin applications including payments, settlement, remittances, and other use cases.
