Sui to Ethereum: 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 Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. Sui and Ethereum 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.

ETH input versus ARB output representation

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. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

Mistakes specific to ETH Sui to ARB Ethereum

Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for Ethereum; 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. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

ETH input identity and handling

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. 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.

ARB output identity and receiving

Arbitrum is classified as a governance or utility token for this route. ARB uses a network-specific contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

Private Route for ETH → ARB

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

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

What should be matched before sending ETH?
