Sui to Linea: 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 Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. Sui and Linea 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 BNB 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. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

Converting stablecoin USDT into BNB

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 BNB is classified as native-asset. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.

Mistakes specific to USDT Sui to BNB Linea

Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for Linea; 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 Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

Private Route for USDT → BNB

Sui account, object, transaction-effect, and fee activity remain public, and Linea wallet, token-transfer, contract, log, and gas activity remain public. For this USDT on Sui to BNB on Linea 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.
