About ETH on Arbitrum
ETH on Arbitrum is ETH held and used on the Arbitrum Layer 2 network, an Ethereum scaling network that posts transaction data back to Ethereum mainnet. On Arbitrum, ETH is the asset used to pay for gas, including transfers, contract calls, and activity across L2 apps. It represents the same underlying ETH as mainnet ETH, but it is held and used on a separate network with its own network setting in your wallet. When you send, receive, or hold ETH, confirm whether your balance should be on Arbitrum or Ethereum mainnet. Choosing the wrong network can leave funds on a chain you did not intend.
