What WBTC representation leaves Polygon?
WBTC is a contract representation on Polygon with 8 decimals at 0x1BFD67037B42Cf73acF2047067bd4F2C47D9BfD6. POL, not WBTC, pays gas unless both symbols are the same. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
What WBTC representation arrives on zkSync Era?
WBTC is a contract representation on zkSync Era with 8 decimals at 0xBBeB516fb02a01611cBBE0453Fe3c580D7281011. ETH, not WBTC, pays gas unless both symbols are the same. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
Does the same WBTC ticker guarantee the same ledger form?
No. This bridge keeps the asset intent while moving between a WBTC wrapped token and a WBTC wrapped token. Match the source and output details in the live quote.
Which gas balances matter for this bridge?
A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. The bridge output does not automatically fund every later gas need.
What destination address should be used?
EVM 0x account address Do not substitute a Polygon address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Polygon, selecting a representation not listed by the quote, or entering an address invalid for zkSync Era can prevent normal detection or receipt.
Can I bridge WBTC from Polygon to ZKsync Era without KYC?
Requirements are checked for the live WBTC Polygon to ZKsync Era 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.
