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 createCryptoPayment() { 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.

Multi-Chain

Access broad ecosystems

USDC and Circle APIs are available across eight blockchain networks, which offer a variety of capabilities and developer environments to choose from to suit your use case.

Cross-Chain Transfer Protocol (CCTP) is a permissionless on-chain utility that facilitates USDC transfers between blockchains via native burning and minting.

Build on CCTP to create mainstream experiences that stack together functions like trading, lending, payments, NFTs, gaming, and more – all while abstracting complexity away from users.

CCTP is live on testnet for Ethereum and Avalanche and expected on mainnet in Q2-23.
