What WBTC representation leaves Ethereum?
WBTC is a contract representation on Ethereum at 0x2260fac5e5542a773aa44fbcfedf7c193bc2c599. ETH, not WBTC, pays gas unless both symbols are the same. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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 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 receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. 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?
An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. 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 Ethereum address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Ethereum, selecting a representation not listed by the quote, or entering an address invalid for Polygon can prevent normal detection or receipt.
Can I bridge WBTC from Ethereum to Polygon without KYC?
Requirements are checked for the live WBTC Ethereum to 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.
