Connect a wallet to Arc Testnet using one-click setup or manual configuration.

Wallet setup

Use the button below to add Arc Testnet to your wallet automatically.

Manual setup

Arc uses USDC as the native gas token (18 decimals). If your wallet supports custom gas tokens, ensure display/decimals are set correctly. Wallets that don’t support custom gas tokens still work for signing and sending transactions — balances may display as “ETH” but the underlying token is USDC. See Gas and fees for details.
