Ethereum to Sui: object and account boundary

An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Ethereum 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.

BNB input versus ETH output representation

Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Mistakes specific to BNB Ethereum to ETH Sui

Route-specific mistakes include sending on a network other than Ethereum; using a destination that is not valid for Sui; running out of ETH before the source transaction is submitted; assuming evm and other addresses are interchangeable. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

BNB input identity and handling

BNB is classified as a native asset for this route. BNB uses a network-specific contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling.

ETH output identity and receiving

Ethereum is classified as a native asset for this route. ETH uses a network-specific contract asset on Sui. The recorded Sui representation uses 8 decimal places. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Private Route for BNB → ETH

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

Swap BNB on Ethereum to ETH on Sui FAQs

How does the Sui coin-object side differ from the other network?

Sui uses Move coin types and objects with SUI gas. The other side follows EVM execution, so addresses and token identifiers are not interchangeable.

What exactly leaves Ethereum as BNB?

BNB is a contract representation on Ethereum at 0xb8c77482e45f1f44de1745f52c74426c631bdd52. ETH, not BNB, pays gas unless both symbols are the same. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling.

What exactly arrives on Sui as ETH?

ETH is a contract representation on Sui with 8 decimals at 0xd0e89b2af5e4910726fbcd8b8dd37bb79b29e5f83f7491bca830e94f7f226d29::eth::ETH. SUI, not ETH, pays gas unless both symbols are the same. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Why does the BNB to ETH direction matter?

Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. On receipt, Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

What changes between the source and destination asset roles?

BNB is the deposited native-asset input; ETH is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.

What should be matched before sending BNB?

Native BNB can fund value and BSC gas, while tokenized BNB requires the source chain’s gas asset and contract handling. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

What funds the Ethereum source transaction?

ETH is the native gas asset for Ethereum. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. BNB is token-tracked and can need approval before transfer.

Can I swap BNB on Ethereum to ETH on Sui without KYC?

Requirements are checked for the live BNB Ethereum to ETH Sui quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
