Privacy for the Ethereum to Sui direction
Where offered, Private Route is intended to reduce an obvious direct association between the Ethereum sending wallet and Sui receiving wallet; it does not hide either blockchain. ETH is the native gas asset for Ethereum. 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.
Ethereum source-side visibility
Ethereum exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. It is the settlement-layer EVM network for this inventory. ERC-20 transfers can require a separate approval, base fee and priority fee affect source cost, and an L1 token contract does not establish an L2 representation. 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.
Ethereum deposit role versus Sui receipt role
An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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.
