Choose the WETH 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.
WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Sui. The recorded Sui representation uses 8 decimal places. The Sui side is contract-tracked rather than a native gas balance. WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Optimism. The recorded Optimism representation uses 18 decimal places. The Optimism side is contract-tracked rather than a native gas balance. WETH leaves as a wrapped contract asset. WETH arrives as a wrapped contract asset.
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; treating a wrapped token as the native gas asset. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Sui account, object, transaction-effect, and fee activity remain public, and Optimism wallet, token-transfer, contract, log, and gas activity remain public. For this WETH on Sui to WETH 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.
WETH is a contract representation on Sui with 8 decimals at 0xaf8cd5edc19c4512f4259f0bee101a40d41ebed738ade5874359610ef8eeced5::coin::COIN. SUI, not WETH, 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. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
WETH is a contract representation on Optimism with 18 decimals at 0x4200000000000000000000000000000000000006. ETH, not WETH, pays gas unless both symbols are the same. 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
No. This bridge keeps the asset intent while moving between a WETH wrapped token and a WETH wrapped token. 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 WETH 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.
