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 Ethereum as POL?
POL is a contract representation on Ethereum at 0x455e53cbb86018ac2b8092fdcd39d8444affc3f6. ETH, not POL, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
Why does the WBTC to POL 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, On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
What changes between the source and destination asset roles?
WBTC is the deposited wrapped-asset input; POL 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. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
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. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.
Can I swap WBTC on Sui to POL on Ethereum without KYC?
Requirements are checked for the live WBTC Sui to POL Ethereum 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.
