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.

ETH input versus USDT output representation

Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. 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 native-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

Mistakes specific to ETH 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. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. 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.

Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.

USDT output identity and receiving

Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Private Route for ETH → USDT

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