Foundational. Composable.
Built to last.

USDC is a core building block of the crypto economy, serving as a trusted, interoperable, and highly liquid digital dollar for thousands of projects running on the world’s leading blockchains.

As the sole issuer of USDC, Circle is committed to supporting developers globally across blockchain communities and helping to deliver the vision of a free, open, and permissionless internet.

Whether you’re just getting started or consider yourself a seasoned developer, it’s easy to integrate USDC into your app or dApp today. USDC is open-source, composable, and accessible for anyone to build upon.

Developers

More than just a stablecoin

USDC is an open platform for digital dollars running on global, always-on infrastructure. Developers build on USDC to connect their products to an uber-money API that delivers 24/7 liquidity and near-instant payments to anyone with an internet connection.

Leading payment service providers built on USDC to transcend the traditional banking system’s limitations and deliver real-time settlement to their customers.

Institutional DeFi protocols like Credix use USDC for stable, programmable liquidity their users can trust. Novel DeFi apps like Friktion leverage USDC in on-chain structured products as their trusted digital dollar of choice.

USDC’s reach is ever-growing as Circle continues to bring USDC to more of the world’s leading blockchains and contribute to open crypto payment standards. USDC is a platform designed to keep pace with the speed of Web3 innovation.

Multichain

Interoperable for a multichain world

USDC is available natively on 8 blockchains, with more integrations expected. For EVM-compatible chains and Flow, USDC is deployed via smart contract. For non-EVM chains, USDC uses built-in token primitives.

Bridged

Extensible to any blockchain

With the help of public bridge infrastructure, USDC can be easily bridged* from any of its native blockchain implementations to reach additional chains.

Polygon USDC*

Bridged from Ethereum via the Polygon Bridge, Polygon USDC can be transacted on the Polygon Proof-of-Stake (PoS) blockchain.

Fantom USDC

Bridged from Ethereum via the Multichain Bridge, Fantom USDC can be transacted on the Fantom blockchain.

NEAR USDC

Bridged from Ethereum via the Rainbow Bridge, NEAR USDC can be transacted on the NEAR blockchain.

Arbitrum USDC

Bridged from Ethereum via the Arbitrum Bridge, Arbitrum USDC can be transacted on the Arbitrum Layer 2 (L2) network.

There are many other examples of bridged USDC in Web3, including (but not limited to) bridged versions on: Optimism, Harmony, Moonriver, Metis, Moonbeam, Orbit, Osmosis, Evmos, Sifchain and more. With the help of cross-chain bridges, USDC is extensible across blockchains and throughout emerging ecosystems such as Cosmos and Polkadot.

*Please note that the Circle Account only supports native versions of USDC and the following bridged versions of USDC: Polygon USDC.

Maximize your vision.

Do more with USDC.

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

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.

To unlock use cases for automated fiat on/off-ramps and wallet-like experiences, Circle builds composable APIs for payments and treasury functionality – enabling you to do more with USDC. Access Circle’s sandbox to generate deposit addresses, accept fiat and crypto payments, make fiat and crypto payouts, and manage end-user balances.

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.

The Centre Consortium, a stablecoin standards organization founded by Circle and Coinbase, has set forth guidelines for blacklisting policies. If an individual violates U.S. law and is pursued by law enforcement, Circle will follow appropriate financial crime compliance measures, including Centre’s Network Access Denial Policy, as applicable.

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 5/26/22: Of the total $53B+ USDC in circulation, only $2.7M USDC is currently blocked. A total of 38 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 U.S. government acts through its agencies which must follow the law. There is currently no law that 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 U.S. government, that public blockchains and well-regulated stablecoins like USDC are important to U.S. economic competitiveness. Circle expects to see a variety of proposals from the U.S. Congress for how to best regulate - not ban - stablecoins.

USDC reserves (cash and short-dated U.S. treasuries) are held in accounts designated ‘for the benefit of customers’ and there are bankruptcy protections. Circle does not and will not use USDC reserves to run its business or to pay its debts. U.S. money transmitter laws are in place to protect holders of USDC in the unlikely event that Circle could not operate its business.

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 U.S. treasuries, USDC is always redeemable 1:1 for U.S. dollars.

Setting a blueprint for

stablecoin standards.

USDC is often looked to as the blueprint to replicate for digital currency architecture. At the highest level, Circle works closely with U.S. congressional leaders to align the open values of Web3 with the traditional financial system and help create our harmonious, interconnected future.
