Arc is Circle's Layer-1 where USDC is the gas token — every fee is priced in dollars, finality lands in under a second. This page watches the public testnet live, straight from your browser via JSON-RPC. No backend, no tracking.
Arc Testnet speaks standard Ethereum JSON-RPC — your existing tooling (ethers, viem, Foundry, Hardhat) works out of the box. Gas is USDC with 18 native decimals, so fees are always legible in dollars. Grab test USDC from the faucet and deploy.
