Choose the ETH asset and Sui network you currently hold.
Check the estimated output, fees, timing, and Optimism destination network.
Open the live route and follow the exact deposit instructions.
Use the receipt and status page until the destination funds arrive.
A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. Sui and Optimism use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.
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.
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. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
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. The Sui side is contract-tracked rather than a native gas balance. Native ETH exists on multiple recorded origin networks; other network forms require representation checks. Ethereum is classified as a native asset for this route. ETH uses a native asset on Optimism. The recorded Optimism representation uses 18 decimal places. Native ETH exists on multiple recorded origin networks; other network forms require representation checks. ETH leaves as a network-specific contract asset. ETH arrives as a native asset. The ticker remains the same while the ledger representation changes across the route.
Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for Optimism; running out of SUI before the source transaction is submitted; assuming other and evm addresses are interchangeable. 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.

Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Sui account, object, transaction-effect, and fee activity remain public, and Optimism wallet, token-transfer, contract, log, and gas activity remain public. For this ETH on Sui to ETH on Optimism 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.
Sui is the Sui side. Its Move coin types, address, objects, and SUI gas do not transfer as EVM contract metadata.
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 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.
ETH is listed as the native representation on Optimism; ETH is used for network gas. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
No. This bridge keeps the asset intent while moving between a ETH contract token and a native ETH. Match the source and output details in the live quote.
A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. The bridge output does not automatically fund every later gas need.
EVM 0x account address Do not substitute a Sui address merely because a wallet displays both networks.
Sending on a network other than Sui, selecting a representation not listed by the quote, or entering an address invalid for Optimism can prevent normal detection or receipt.
Requirements are checked for the live ETH Sui to Optimism 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.
