Use the receipt and status page until the destination funds arrive.

What you need to know

Sui to Arbitrum: 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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Sui and Arbitrum 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 ETH 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. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

ETH keeps its ticker while changing ledgers

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 Arbitrum. The recorded Arbitrum 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.

Sui to Arbitrum bridge mistakes

Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for Arbitrum; 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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. 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 ETH → ETH

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

Which side uses Sui coin objects and SUI gas?

Sui is the Sui side. Its Move coin types, address, objects, and SUI gas do not transfer as EVM contract metadata.

What ETH representation leaves Sui?

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.

What ETH representation arrives on Arbitrum?

ETH is listed as the native representation on Arbitrum; ETH is used for network gas. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.

Does the same ETH ticker guarantee the same ledger form?

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.

Which gas balances matter for this bridge?

A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. The bridge output does not automatically fund every later gas need.

What destination address should be used?

EVM 0x account address Do not substitute a Sui address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

Sending on a network other than Sui, selecting a representation not listed by the quote, or entering an address invalid for Arbitrum can prevent normal detection or receipt.

Can I bridge ETH from Sui to Arbitrum without KYC?

Requirements are checked for the live ETH Sui to Arbitrum 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.
