WETH input identity and handling
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Arbitrum. The recorded Arbitrum representation uses 18 decimal places. 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.
Leaving Arbitrum L2 for Hyperliquid (HyperEVM) L1
Arbitrum inclusion and its ethereum settlement are distinct from final receipt on Hyperliquid (HyperEVM). The live route, rather than a generic rollup withdrawal assumption, determines the provider path and timing for this direction.
WETH unwrap or exchange input 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 source token on Arbitrum. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Hyperliquid (HyperEVM) destination execution
Hyperliquid (HyperEVM) is a L1 EVM network in the Hyperliquid ecosystem. HYPE pays destination-side network gas on Hyperliquid (HyperEVM). EVM 0x account address; confirm the destination is HyperEVM A HyperEVM receipt belongs to its EVM execution state and uses HYPE for later gas; it should not be interpreted as a HyperCore position or vault balance.
WBTC output identity and receiving
Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Hyperliquid (HyperEVM). The recorded Hyperliquid (HyperEVM) representation uses 8 decimal places. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
Arbitrum source execution
Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Arbitrum. EVM 0x account address On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval.
EVM-to-EVM execution boundary
Arbitrum and Hyperliquid (HyperEVM) can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories. The recorded settlement context includes ethereum, so L1 and L2 confirmation behavior should not be assumed identical.
Mistakes specific to WETH Arbitrum to WBTC Hyperliquid (HyperEVM)
Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Hyperliquid (HyperEVM); running out of ETH before the source transaction is submitted; treating a wrapped token as the native gas asset. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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 HyperEVM receipt belongs to its EVM execution state and uses HYPE for later gas; it should not be interpreted as a HyperCore position or vault balance.
