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.
