Hyperliquid (HyperEVM) to Sui: object and account boundary
A HyperEVM source spends HYPE for EVM gas; HyperCore balances, vault positions, and other Hyperliquid account states are not interchangeable inputs. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Hyperliquid (HyperEVM) 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.
USDT input versus WETH output representation
The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Converting stablecoin USDT into WETH
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 source is a stablecoin contract or recorded native representation, while WETH is classified as token. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
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 USDT Hyperliquid (HyperEVM) to WETH Sui
Route-specific mistakes include sending on a network other than Hyperliquid (HyperEVM); using a destination that is not valid for Sui; running out of HYPE before the source transaction is submitted; assuming evm and other addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. A HyperEVM source spends HYPE for EVM gas; HyperCore balances, vault positions, and other Hyperliquid account states are not interchangeable inputs. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. 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.
USDT input identity and handling
Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Hyperliquid (HyperEVM). The recorded Hyperliquid (HyperEVM) representation uses 18 decimal places. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.
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.
