What exactly leaves Scroll as ETH?
ETH is listed as the native representation on Scroll; ETH is used for network gas. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
