What you need to know

BNB Chain to Sui: object and account boundary

A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. BNB Chain and Sui use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.

Sui coin-object and SUI gas requirements

SUI is the native gas asset for Sui. Sui hexadecimal account address with an object-based asset model Coin objects and Move types are not EVM token contracts.

WETH input versus WETH output representation

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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

WETH keeps its ticker while changing ledgers

WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on BNB Chain. The recorded BNB Chain representation uses 18 decimal places. The BNB Chain side is contract-tracked rather than a native gas balance. WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Sui. The recorded Sui representation uses 8 decimal places. The Sui side is contract-tracked rather than a native gas balance. WETH leaves as a wrapped contract asset. WETH arrives as a wrapped contract asset.

Private Route for WETH → WETH

BNB Chain wallet, token-transfer, contract, log, and gas activity remain public, and Sui account, object, transaction-effect, and fee activity remain public. For this WETH on BNB Chain to WETH on Sui path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side Sui hexadecimal account address with an object-based asset model; it does not hide either chain's public records.
