What exactly leaves Polygon as WBTC?
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 exactly arrives on BNB Chain as DOGE?
DOGE is a contract representation on BNB Chain with 8 decimals at 0xbA2aE424d960c26247Dd6c32edC70B295c744C43. BNB, not DOGE, pays gas unless both symbols are the same. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. Native DOGE receipt creates a Dogecoin UTXO at a compatible address; tokenized DOGE instead appears under a destination contract.
Why does the WBTC to DOGE direction matter?
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. On receipt, Native DOGE receipt creates a Dogecoin UTXO at a compatible address; tokenized DOGE instead appears under a destination contract.
What changes between the source and destination asset roles?
WBTC is the deposited wrapped-asset input; DOGE 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 WBTC?
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. Native DOGE receipt creates a Dogecoin UTXO at a compatible address; tokenized DOGE instead appears under a destination contract.
Can the wrapped asset pay native network gas?
No. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas.
What funds the Polygon source transaction?
POL is the native gas asset for Polygon. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. WBTC is token-tracked and can need approval before transfer.
Can I swap WBTC on Polygon to DOGE on BSC without KYC?
Requirements are checked for the live WBTC Polygon to DOGE BSC 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.
