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 Ethereum as ARB?
ARB is a contract representation on Ethereum at 0xb50721bcf8d664c30412cfbc6cf7a15145234ad1. ETH, not ARB, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
Why does the POL to ARB 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, A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
What changes between the source and destination asset roles?
POL is the deposited token input; ARB is the quoted token 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. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
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 Ethereum, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap POL on Arbitrum to ARB on Ethereum without KYC?
Requirements are checked for the live POL Arbitrum to ARB Ethereum 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.
