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 Polygon as LINK?
LINK is a contract representation on Polygon with 18 decimals at 0x53E0bca35eC356BD5ddDFebbD1Fc0fD03FaBad39. POL, not LINK, pays gas unless both symbols are the same. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Why does the OP to LINK 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, LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
What changes between the source and destination asset roles?
OP is the deposited token input; LINK 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 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 Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
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 Polygon, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap OP on OP Mainnet to LINK on Polygon without KYC?
Requirements are checked for the live OP OP Mainnet to LINK Polygon 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.
