Bridged

Extensible to any blockchain

With the help of third-party bridge providers, USDC can be bridged from Ethereum to reach additional blockchains in the form of “Bridged USDC.”

Bridged USDC on Linea

Bridged USDC on zkSync

There are many examples of Bridged USDC, including implementations on emerging blockchain networks such as Aptos, Metis, Orbit, and more.

Maximize your vision.

As an open-source, programmable dollar with global reach, USDC is powerful market infrastructure you can begin building with immediately. Circle exists to make it even faster and easier for developers to realize their vision for USDC.

Fintechs-810x810

We believe the ability to rapidly test and iterate is critical to shipping great products. Use Circle’s multi-chain testnet faucet to begin experimenting with USDC flows within your project.

Circle offers composable APIs for programmable payments and wallet infrastructure. Access Circle Sandbox today to generate wallets, accept and make USDC payments, and manage funds flow between users.

Reach out to us if you’re interested in the production version of Circle’s payments and treasury platform.

FAQ

No, USDC is permissionless, open-source and accessible to anyone to build with. You can add support for USDC in your app or dApp without needing a commercial business relationship with Circle.

If you’re interested in Circle’s APIs, you can start testing for free with a sandbox key.

Circle aims to bring native USDC to all of the largest blockchain ecosystems in Web3.

In addition, the Web3 community has built permissionless bridge infrastructure to enable USDC to flow across blockchains as a bridged asset and add liquidity to emerging ecosystems.

Circle has a blocklisting policy and will follow appropriate financial crime compliance measures. In response to court orders and sanctions compliance, Circle has the ability to deny access to individual wallet addresses from sending and receiving USDC. When an address is denied access, it can no longer receive USDC and USDC held by that address cannot be transferred on-chain.

We take this responsibility very seriously and can share the following data:

  • As of 4/17/23: Of the total $31B+ USDC in circulation, only $8.6M USDC is currently blocked, which is <0.03% of USDC in circulation. A total of 159 unique addresses have ever been blocked to date, all of which comply with OFAC sanctions and court orders.

Importantly, the blocking of addresses emits events on-chain, and we encourage the community to monitor those events. Blocking is never done unilaterally or arbitrarily and follows the highest duty of care.

The US government acts through its agencies which must follow the law. There is currently no suggestion that the law would permit any agency to compel Circle to KYC every holder of USDC. Additionally, Circle does not track every individual who holds USDC.

There is currently bipartisan recognition, at all levels of the US government, that public blockchains and well-regulated stablecoins like USDC are important to US economic competitiveness. Circle expects to see a variety of proposals from the US Congress for how to best regulate - not ban - stablecoins.

USDC reserves are bankruptcy remote, which means they are held separately from Circle’s operating funds for the benefit of USDC holders. USDC is fully backed by cash and short-dated US Treasuries, and those reserves are held in the custody and management of leading US financial institutions.

The key factors to consider for choosing a stablecoin are: (1) what is backing the reserves; (2) how are the reserves managed; and (3) how large and diversified is the market for the stablecoin. There is no other stablecoin that compares to USDC on its reserves backing, reserves management, and liquidity across public blockchains.

As open-source code, USDC can be integrated, bought, sold, lent, borrowed, traded, and spent without ever touching Circle’s commercial products and services. The universe of protocols, wallets, exchanges, merchants, and other market participants that support USDC is expanding because USDC represents stability you can trust. Fully-backed by cash and short-dated US treasuries, USDC is always redeemable 1:1 for US dollars.
