What exactly leaves Linea as ETH?
ETH is listed as the native representation on Linea; ETH is used for network gas. A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. 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.
What exactly arrives on Arbitrum as POL?
POL is a contract representation on Arbitrum with 18 decimals at 0x044d8e7F3A17751D521efEa8CCf9282268fE08CC. ETH, not POL, pays gas unless both symbols are the same. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
Why does the ETH to POL direction matter?
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. On receipt, On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.

What should be matched before sending ETH?

An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
What funds the Linea source transaction?

What is the most dangerous wrong-network mistake here?
Sending ETH on a network other than Linea, or using an address that is not valid for Arbitrum, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap ETH on Linea to POL on Arbitrum without KYC?
Requirements are checked for the live ETH Linea to POL Arbitrum quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
