Build on Circle with USDC
Create the next revolutionary decentralized app with Web3 APIs or integrate fast, regulated digital currency into transactions to serve customers around the world.
async function create CryptoPayment() {
const payment = await
circle.paymentIntents.createPaymentIntent({
idempotencyKey: "5c6e9b91-6563-47ec-8c6d-0ce1103c50b3",
amount: { amount: "3.14", currency: "USD" },
settlementCurrency: "USD",
paymentMethods: [{ chain: "ETH", type: "blockchain" }]
});
}
Sandbox
Test, explore & inspire
Try out Circle Web3 APIs in a workspace that functions just like production. Investigate new workflows or refactor existing applications to minimize bugs and optimize user experience.
- Experiment in a safe environment to help confirm products and services work as expected before going live.
- Test integrations and API calls without performing real financial transactions.
- Create code that easily converts into a production version by switching out URLs and API keys.
API suite
Integrate seamlessly
Leverage Circle’s financial services APIs to accept crypto payments and make near-instant payouts with USDC, or automate transactions for increased efficiency.
Explore our docs
Plan and build your application quickly with well-documented APIs, a robust SDK, and widgets integrated with just a few lines of code.
Accept BTC and ETH payments that automatically settle in USDC, or programmatically access USDC liquidity for capital market trades.
Start with payments, payouts, and transfers, then expand to workflow automation or generate digital asset wallets for your customers.
USDC
Build with fully backed digital currency
Enable transactions using stable digital currency pegged to the U.S. Dollar and fully backed by cash short-dated and U.S. Treasuries. Build applications for finance, asset management, gaming and more, supported by more than $40 billion in USDC and trillions in historic transaction volume*. Use USDC as a flexible, cost-effective component of backend financial infrastructure or give customers simplified access to digital assets and the Web3 ecosystem.
Multi-Chain
Access broad ecosystems
USDC and Circle APIs are available across eight supported blockchains offering a variety of capabilities, communities and development environments, so it’s easy to choose the right configuration for your use case. Cross-Chain Transfer Protocol (CCTP) allows users to permissionlessly swap native USDC between supported blockchains, validated by Circle. Build user experiences that combine some of the best decentralized applications on any supported network by moving chain-switching behind the scenes, or design and implement complex financial transactions with interoperable USDC liquidity in composable, permissionless smart contracts.
