What exactly leaves Polygon as AVAX?
AVAX is a contract representation on Polygon with 18 decimals at 0x2C89bbc92BD86F8075d1DEcc58C7F4E0107f286b. POL, not AVAX, 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. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead.
What exactly arrives on Linea as WBTC?
WBTC is a contract representation on Linea with 8 decimals at 0x3aAB2285ddcDdaD8edf438C1bAB47e1a9D05a9b4. ETH, not WBTC, pays gas unless both symbols are the same. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. 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.
Why does the AVAX to WBTC direction matter?
On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. On receipt, 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.
What changes between the source and destination asset roles?
AVAX is the deposited native-asset input; WBTC is the quoted wrapped-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending AVAX?
On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. 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.
Can the wrapped asset pay native network gas?
No. 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. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract.
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. AVAX is token-tracked and can need approval before transfer.
Can I swap AVAX on Polygon to WBTC on Linea without KYC?
Requirements are checked for the live AVAX Polygon to WBTC Linea 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.
