Overview
Arc is Circle's blockchain where USDC is the native gas token. Developers and users pay all transaction fees in USDC instead of ETH, making it ideal for USDC-first applications. Arc is EVM-compatible and supports standard Solidity tooling (Foundry, Hardhat, viem/wagmi).
Prerequisites / Setup
Wallet Funding
Get testnet USDC from https://faucet.circle.com before sending any transactions.
