What exactly leaves Polygon as WETH?
WETH is a contract representation on Polygon with 18 decimals at 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619. POL, not WETH, 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. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
What exactly arrives on Hyperliquid (HyperEVM) as WBTC?
WBTC is a contract representation on Hyperliquid (HyperEVM) with 8 decimals at 0x0555E30da8f98308EdB960aa94C0Db47230d2B9c. HYPE, not WBTC, pays gas unless both symbols are the same. A HyperEVM receipt belongs to its EVM execution state and uses HYPE for later gas; it should not be interpreted as a HyperCore position or vault balance. 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 WETH to WBTC direction matter?
WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. 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?
WETH is the deposited token 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 WETH?
WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A HyperEVM receipt belongs to its EVM execution state and uses HYPE for later gas; it should not be interpreted as a HyperCore position or vault balance. 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. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A HyperEVM receipt belongs to its EVM execution state and uses HYPE for later gas; it should not be interpreted as a HyperCore position or vault balance.
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. WETH is token-tracked and can need approval before transfer.
Can I swap WETH on Polygon to WBTC on Hyperliquid without KYC?
Requirements are checked for the live WETH Polygon to WBTC Hyperliquid 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.
