The dollar-native chain,
measured in real time.

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.

Your Arc wallet

Circle Developer-Controlled Wallets

Spins up a real Arc Testnet wallet via Circle's Wallets API — no MetaMask, no seed phrase. This is a shared demo wallet-set for this page only: testnet funds only, don't treat it as private. Any send you make here lands in the live feed above, usually within a few seconds.

Deploy a token

Circle Smart Contract Platform

Deploy a real, audited ERC-20 or ERC-721 contract to Arc Testnet from your wallet above, then mint straight to any address — the simplest form of an airdrop. No Solidity, no deploy scripts.

Create a wallet above first — deployment needs a wallet to own the contract.

Build on Arc

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.
