What exactly leaves 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. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. Native POL can pay Polygon PoS gas, while a POL-labelled contract on another network uses that chain’s gas and token-transfer rules.
What exactly arrives on zkSync Era as ETH?
ETH is listed as the native representation on zkSync Era; ETH is used for network gas. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Why does the POL to ETH direction matter?
Native POL can pay Polygon PoS gas, while a POL-labelled contract on another network uses that chain’s gas and token-transfer rules. On receipt, Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
What changes between the source and destination asset roles?
POL is the deposited token input; ETH is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending POL?
Native POL can pay Polygon PoS gas, while a POL-labelled contract on another network uses that chain’s gas and token-transfer rules. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
What funds the Arbitrum source transaction?
ETH is the native gas asset for Arbitrum. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. POL is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending POL on a network other than Arbitrum, or using an address that is not valid for zkSync Era, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap POL on Arbitrum to ETH on zkSync without KYC?
Requirements are checked for the live POL Arbitrum to ETH zkSync 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.
