How does the Sui coin-object side differ from the other network?
Sui uses Move coin types and objects with SUI gas. The other side follows EVM execution, so addresses and token identifiers are not interchangeable.
What exactly leaves Sui as WBTC?
WBTC is a contract representation on Sui with 8 decimals at 0x027792d9fed7f9844eb4839566001bb6f6cb4804f66aa2da6fe1ee242d896881::coin::COIN. SUI, not WBTC, pays gas unless both symbols are the same. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. 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 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 receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Why does the WBTC to WETH 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, WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
What changes between the source and destination asset roles?
WBTC is the deposited wrapped-asset input; WETH 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 Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
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 Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas.
Can I swap WBTC on Sui to WETH on Polygon without KYC?
Requirements are checked for the live WBTC Sui to WETH 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.
