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 Avalanche as USDC?
USDC is a contract representation on Avalanche at 0xb97ef9ef8734c71904d8002f8b6bc66dd9c48a6e. AVAX, not USDC, pays gas unless both symbols are the same. An Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain contract. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Why does the WBTC to USDC 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, The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
What changes between the source and destination asset roles?
WBTC is the deposited wrapped-asset input; USDC is the quoted stablecoin 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. An Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain contract. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Which stablecoin contract must this route match?
USDC must match the quoted Avalanche representation. A ticker or target price is not enough to identify a token 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. An Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain contract.
Can I swap WBTC on Polygon to USDC on Avalanche without KYC?
Requirements are checked for the live WBTC Polygon to USDC Avalanche 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.
