What exactly leaves Optimism as OP?
OP is a contract representation on Optimism at 0x4200000000000000000000000000000000000042. ETH, not OP, 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. OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network.
What exactly arrives on Hyperliquid (HyperEVM) as ETH?
ETH is a contract representation on Hyperliquid (HyperEVM) with 18 decimals at 0x1fbcCdc677c10671eE50b46C61F0f7d135112450. HYPE, not ETH, pays gas unless both symbols are the same. 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. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Why does the OP to ETH direction matter?
OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network. On receipt, Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
What changes between the source and destination asset roles?
OP is the deposited token input; ETH is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending OP?
OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network. 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 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. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
What funds the Optimism source transaction?
ETH is the native gas asset for Optimism. 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. OP is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending OP on a network other than Optimism, or using an address that is not valid for Hyperliquid (HyperEVM), can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap OP on OP Mainnet to ETH on Hyperliquid without KYC?
Requirements are checked for the live OP OP Mainnet to ETH Hyperliquid 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.
