What you need to know

Ethereum to Sui: object and account boundary

An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Ethereum 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 WETH 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

WETH wrapped-token output check

WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH is the destination token on Sui. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Mistakes specific to LINK Ethereum to WETH Sui

Route-specific mistakes include sending on a network other than Ethereum; 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 Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

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 Ethereum. The Ethereum 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.

WETH output identity and receiving

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. 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 LINK → WETH

Ethereum 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 Ethereum 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.

Swap LINK on Ethereum to WETH on Sui FAQs

How does the Sui coin-object side differ from the other network?

Sui uses Move coin types and objects with SUI gas. The other side follows EVM execution, so addresses and token identifiers are not interchangeable.

What exactly leaves Ethereum as LINK?

LINK is a contract representation on Ethereum at 0x514910771af9ca656af840dff83e8264ecf986ca. ETH, not LINK, pays gas unless both symbols are the same. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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.

What exactly arrives on Sui as WETH?

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.

Why does the LINK to WETH direction matter?

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. On receipt, WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

What changes between the source and destination asset roles?

LINK is the deposited token input; WETH 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 LINK?

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. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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.

Can the wrapped asset pay native network gas?

No. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance.

Can I swap LINK on Ethereum to WETH on Sui without KYC?

Requirements are checked for the live LINK Ethereum to WETH 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.
