SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Developers building USDC-first payment or DeFi applications need correct network configuration, token addresses, and deployment patterns for Arc, Circle's EVM-compatible blockchain where USDC is the native gas token, without hunting through scattered documentation. ## Core Features & Use Cases - Network Configuration: Provides Arc Testnet chain ID (5042002), RPC endpoints, explorer, faucet, and CCTP domain for immediate setup with wagmi, viem, Foundry, or Hardhat. - Deployment Patterns: Includes ready-to-use patterns for React frontends, Foundry smart contract deployment, Circle's pre-audited contract templates, and bridging USDC via CCTP. - Use Case: A developer building a USDC payment app uses this Skill to configure wagmi with arcTestnet, fund a wallet from the Circle faucet, and deploy a Solidity contract to Arc Testnet with correct 18-decimal gas handling. ## Quick Start Set up a wagmi config for Arc Testnet and deploy my Solidity contract to Arc using Foundry with USDC gas.

FAQPage Schema
How do I deploy a smart contract to Arc Testnet?▼

Deploy to Arc Testnet using Foundry's forge create command with the RPC URL https://rpc.testnet.arc.network and a funded deployer wallet. Arc is EVM-compatible, so standard Solidity contracts work without modification beyond chain configuration.

How do I configure Arc Testnet in wagmi or viem?▼

Arc Testnet is available by default in viem as the arcTestnet chain definition, so no custom chain config is needed. Import arcTestnet from viem/chains and pass it to your wagmi config with an HTTP transport.

Does Arc use ETH for gas fees?▼

No, Arc uses USDC as its native gas token, so no ETH is needed for any transaction. Native gas amounts use 18 decimals like ETH on other chains, while ERC-20 USDC uses 6 decimals.

How do I bridge USDC to Arc using CCTP?▼

Bridge USDC to Arc using Circle's Cross-Chain Transfer Protocol with Arc's CCTP domain 26. The bridging workflow follows the standard CCTP burn-and-mint pattern from supported source chains.

Can I deploy to Arc mainnet?▼

No, Arc is currently testnet only, and all addresses and configuration apply to testnet exclusively. Fund your wallet with testnet USDC from the Circle faucet at faucet.circle.com before sending transactions.
