What exactly leaves Arbitrum as ARB?
ARB is a contract representation on Arbitrum at 0x912ce59144191c1204e64559fe8253a0e49e6548. ETH, not ARB, 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. Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum.
What exactly arrives on Polygon as POL?
POL is listed as the native representation on Polygon; POL is used for network gas. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
Why does the ARB to POL direction matter?
Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. On receipt, On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
What changes between the source and destination asset roles?
ARB is the deposited token input; POL 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 ARB?
Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not 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. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
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. ARB is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending ARB on a network other than Arbitrum, or using an address that is not valid for Polygon, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap ARB on Arbitrum to POL on Polygon without KYC?
Requirements are checked for the live ARB Arbitrum to POL Polygon 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.
