LINK is a contract representation on zkSync Era at 0x52869bae3e091e36b0915941577f2d47d8d8b534. ETH, not LINK, 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. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract.
What exactly arrives on zkSync Era as WBTC?
