4. Track delivery

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

What you need to know

Optimism to Sui: object and account boundary

An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Optimism and Sui 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.

WETH input versus WETH output representation

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 keeps its ticker while changing ledgers

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 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 leaves as a wrapped contract asset. WETH arrives as a wrapped contract asset.

Optimism to Sui bridge mistakes

Route-specific mistakes include sending on a network other than Optimism; using a destination that is not valid for Sui; running out of ETH before the source transaction is submitted; assuming evm and other addresses are interchangeable; treating a wrapped token as the native gas asset. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. 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. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Private Route for WETH → WETH

Optimism wallet, token-transfer, contract, log, and gas activity remain public, and Sui account, object, transaction-effect, and fee activity remain public. For this WETH on Optimism to WETH on Sui path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side Sui hexadecimal account address with an object-based asset model; it does not hide either chain's public records.

Optimism to Sui 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 WETH representation leaves Optimism?

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 source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. 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.

What WETH representation arrives on Sui?

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 receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Does the same WETH ticker guarantee the same ledger form?

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.

Which gas balances matter for this bridge?

An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. The bridge output does not automatically fund every later gas need.

What destination address should be used?

Sui hexadecimal account address with an object-based asset model Do not substitute a Optimism address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

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

Can I bridge WETH from Optimism to Sui without KYC?

Requirements are checked for the live WETH Optimism to Sui 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.
