Privacy for the Polygon to Sui direction
Where offered, Private Route is intended to reduce an obvious direct association between the Polygon sending wallet and Sui receiving wallet; it does not hide either blockchain. POL is the native gas asset for Polygon. EVM 0x account address SUI is the native gas asset for Sui. Sui hexadecimal account address with an object-based asset model Similar amounts, timing, address reuse, and later consolidation can still add association signals. Identity requirements must be checked separately.
Polygon source-side visibility
Polygon exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Polygon PoS uses an EVM sidechain architecture with its own validator checkpoints and gas balance. Its token representations and bridge behavior are separate from Ethereum L1 even when wallets use the same 0x account. The source deposit, gas funding, asset representation, confirmations, and sending-address history remain outside any promise of invisibility.
Sui destination-side visibility
Sui can expose addresses or accounts, transfers, amounts, fees, and timing according to its other transaction model. It uses an object-centric Move execution model in which owned and shared objects participate in transactions. Sui addresses and coin objects are not EVM token contracts, and SUI is required for gas and storage-related execution. The destination delivery and later activity can remain observable even when the provider path reduces a direct association.
Polygon deposit role versus Sui receipt role
A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. Those deposit-side events remain public. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. The receipt and later activity remain public.
WETH wrapper and unwrap evidence; WETH wrapper and unwrap evidence
WETH approvals, wrapper transfers, and later unwrap activity remain visible contract events. A private route does not turn WETH into an unrecorded native ETH balance. 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. The source transfer remains public. WETH approvals, wrapper transfers, and later unwrap activity remain visible contract events. A private route does not turn WETH into an unrecorded native ETH balance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. The destination receipt and later use remain public even when direct wallet association is reduced.
Cross-chain linkability limits
Private routing can reduce direct association across Sui objects and the other ledger account. Move object changes, gas, the other-network receipt, amounts, timing, and later transfers remain public. 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. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Verification status is separate from privacy status
Support for the exact Sui coin type or object-side asset, other network representation, amount, and region is evaluated by the live provider. Privacy intent does not establish no-KYC status. 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. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
