Sui to Optimism: 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. 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 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.

SUI input versus ETH output representation

Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. 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 SUI Sui to ETH Optimism

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 SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. 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.

SUI input identity and handling

Sui is classified as a native asset for this route. SUI uses a native asset on Sui. The Sui side is contract-tracked rather than a native gas balance. Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model.

ETH output identity and receiving

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. 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 SUI → ETH

Sui account, object, transaction-effect, and fee activity remain public, and Optimism wallet, token-transfer, contract, log, and gas activity remain public. For this SUI 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.
