Native gas on Arc is USDC (18-decimal math). Figures are estimates at the current gas price — actual gas used varies by contract, calldata, and state.

Native gas is USDC (18-decimal); the USDC ERC-20 above is 6-decimal. Adding the network is a config action only — Arclight never handles your keys.
