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 Linea as ETH?
ETH is listed as the native representation on Linea; ETH is used for network gas. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. 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 Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. 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 Linea, 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 Linea without KYC?
Requirements are checked for the live OP OP Mainnet to ETH Linea 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.
