What exactly leaves zkSync Era as ETH?
ETH is listed as the native representation on zkSync Era; ETH is used for network gas. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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 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 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 changes between the source and destination asset roles?
ETH 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 ETH?
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. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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 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. ETH is recorded as native on this source.
What is the most dangerous wrong-network mistake here?
Sending ETH on a network other than zkSync Era, 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 ETH on zkSync to POL on Polygon without KYC?
Requirements are checked for the live ETH zkSync 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.
