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.

LINK input versus USDT output representation

LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Receiving stablecoin USDT

USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. The destination wallet must support the exact Sui representation. The route converts a token source into a stablecoin balance; the destination ticker alone is not a contract check.

Mistakes specific to LINK Optimism to USDT Sui

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; selecting a stablecoin by ticker without checking its network contract. 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. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

LINK input identity and handling

Chainlink is classified as a governance or utility token for this route. LINK uses a network-specific contract asset on Optimism. The Optimism side is contract-tracked rather than a native gas balance. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract.

USDT output identity and receiving

Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Sui. The recorded Sui representation uses 6 decimal places. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Private Route for LINK → USDT

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