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.Documentation Index

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
| Quickstart | What you’ll build |
|---|---|
| Send tokens | Transfer stablecoins between wallets on the same blockchain. |
| Bridge tokens across blockchains | Bridge USDC between EVM chains, Solana, or using Circle Wallets. |
| Swap tokens | Exchange one token for another on the same blockchain. |
| Swap tokens across chains | Swap and bridge tokens in a single flow. |
| Deposit and spend a Unified Balance | Deposit USDC from multiple chains into a Unified Balance, then spend on another blockchain. |
| Delegate deposit and spend | Let a backend delegate wallet fund and spend a user’s Unified Balance. |
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.| Quickstart | What you’ll build |
|---|---|
| Deploy contracts | Deploy pre-audited ERC-20, ERC-721, and ERC-1155 templates with Circle Contracts. |
| Interact with contracts | Mint, transfer, and airdrop tokens using deployed contracts. |
| Monitor contract events | Set 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.
