Sui to BNB Chain: object and account boundary
A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. Sui and BNB Chain 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 USDT 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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
Receiving stablecoin USDT
USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. The destination wallet must support the exact BNB Chain representation. The route converts a token source into a stablecoin balance; the destination ticker alone is not a contract check.
WETH unwrap or exchange input check
WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH is the source token on Sui. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Mistakes specific to WETH Sui to USDT BNB Chain
Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for BNB Chain; running out of SUI before the source transaction is submitted; assuming other and evm addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. 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 BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
WETH input identity and handling
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. 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.
USDT output identity and receiving
Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on BNB Chain. The recorded BNB Chain representation uses 18 decimal places. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
