What exactly leaves zkSync Era as BNB?
BNB is a contract representation on zkSync Era with 18 decimals at 0x7400793aAd94C8CA801aa036357d10F5Fd0ce08f. ETH, not BNB, pays gas unless both symbols are the same. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling.
What exactly arrives on Ethereum as POL?
POL is a contract representation on Ethereum at 0x455e53cbb86018ac2b8092fdcd39d8444affc3f6. ETH, not POL, 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. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
Why does the BNB to POL direction matter?
Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. 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?
BNB is the deposited native-asset 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 BNB?
Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
What funds the zkSync Era source transaction?
ETH is the native gas asset for zkSync Era. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. BNB is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending BNB on a network other than zkSync Era, 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 BNB on zkSync to POL on Ethereum without KYC?
Requirements are checked for the live BNB zkSync to POL 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.
