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.
USDT input versus ARB output representation
The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
Converting stablecoin USDT into ARB
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 source is a stablecoin contract or recorded native representation, while ARB is classified as token. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
Mistakes specific to USDT Sui to ARB 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. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
USDT input identity and handling
Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Sui. The recorded Sui representation uses 6 decimal places. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.
ARB output identity and receiving
Arbitrum is classified as a governance or utility token for this route. ARB uses a network-specific contract asset on BNB Chain. The recorded BNB Chain representation uses 18 decimal places. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
