​
Quickstarts

Step-by-step guides to get a working integration running in minutes.
QuickstartWhat you’ll build
Deploy contractsDeploy ERC-20, ERC-721, and ERC-1155 contracts on Arc testnet.
Transfer stablecoinsSend USDC or EURC between wallets on Arc.
Bridge USDC to ArcMove USDC from another blockchain to Arc using CCTP.
Access USDC crosschainDeposit and withdraw USDC through Circle Gateway.
Interact with contractsMint, transfer, and airdrop tokens using deployed contracts.
Monitor contract eventsSet up webhooks and event monitors for onchain activity.

​
App Kit

App Kit is an SDK for building payment and liquidity workflows across blockchains. Add bridging, swapping, and token transfers to your app in a few lines of code.

Bridge

Transfer USDC across blockchains using CCTP.

Swap

Exchange one token for another on the same blockchain.

Send

Transfer tokens between wallets on the same blockchain.
See the full installation guide to get started, or browse supported blockchains and the SDK reference.
