Arc gives you a complete developer platform for building financial applications with stablecoins. Use App Kit to add crosschain payment workflows in a few lines of code, deploy smart contracts on a purpose-built L1 network, or integrate third-party developer tools for RPC access, data indexing, and compliance.

Get started

Connect to Arc

RPC endpoints, chain ID, and network configuration for Arc testnet.

Deploy on Arc

Deploy, test, and interact with a Solidity smart contract on Arc.

App Kit

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

Send

Transfer tokens between wallets on the same blockchain.

Bridge

Transfer USDC across blockchains using CCTP.

Swap

Exchange one token for another on the same blockchain.

Unified Balance

Combine USDC from multiple blockchains into a single, instantly spendable balance.

App Kit quickstarts

QuickstartWhat you’ll build
Send tokensTransfer stablecoins between wallets on the same blockchain.
Bridge tokens across blockchainsBridge USDC between EVM chains, Solana, or using Circle Wallets.
Swap tokensExchange one token for another on the same blockchain.
Swap tokens across chainsSwap and bridge tokens in a single flow.
Deposit and spend a Unified BalanceDeposit USDC from multiple chains into a Unified Balance, then spend on another blockchain.
Delegate deposit and spendLet a backend delegate wallet fund and spend a user’s Unified Balance.
See the full installation guide to get started, or browse supported blockchains and the SDK reference.

Network quickstarts

Step-by-step guides for working directly with the Arc network. Most tutorials require an Arc testnet RPC connection and a funded wallet.
QuickstartWhat you’ll build
Deploy contractsDeploy pre-audited ERC-20, ERC-721, and ERC-1155 templates with Circle Contracts.
Interact with contractsMint, transfer, and airdrop tokens using deployed contracts.
Monitor contract eventsSet up webhooks and event monitors for onchain activity.

Developer tools

Account abstraction

Smart wallets, paymasters, and session keys from ecosystem providers.

Node providers

Managed RPC access from Alchemy, QuickNode, Blockdaemon, and dRPC.

Data indexers

Query onchain data with Envio, Goldsky, The Graph, and Thirdweb.

Compliance

Transaction monitoring and wallet screening from Elliptic and TRM Labs.
