What exactly leaves Base as LINK?
LINK is a contract representation on Base at 0x88fb150bdc53a65fe94dea0c9ba0a6daf8c6e196. ETH, not LINK, pays gas unless both symbols are the same. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. 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 Ethereum as POL?
POL is a contract representation on Ethereum at 0x455e53cbb86018ac2b8092fdcd39d8444affc3f6. ETH, not POL, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. 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. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
What funds the Base source transaction?
ETH is the native gas asset for Base. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. 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 Base, or using an address that is not valid for Ethereum, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap LINK on Base to POL on Ethereum without KYC?
Requirements are checked for the live LINK Base to POL Ethereum 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.
