What exactly leaves Optimism as LINK?
LINK is a contract representation on Optimism at 0x350a791bfc2c21f9ed5d10980dad2e2638ffa7f6. ETH, not LINK, 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. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract.
What exactly arrives on Polygon as POL?
POL is listed as the native representation on Polygon; POL is used for network gas. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
Why does the LINK to POL direction matter?
LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. On receipt, On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
What changes between the source and destination asset roles?
LINK is the deposited token input; POL 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 LINK?
LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. 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. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
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. LINK is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending LINK 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 LINK on OP Mainnet to POL on Polygon without KYC?
Requirements are checked for the live LINK OP Mainnet to POL 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.
