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 BNB Chain as ARB?
ARB is a contract representation on BNB Chain with 18 decimals at 0x0acdb582C1d5512Ea31fD64b9C07882CB31E494D. BNB, not ARB, pays gas unless both symbols are the same. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
Why does the LINK to ARB 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, A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
What changes between the source and destination asset roles?
LINK is the deposited token input; ARB 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 BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
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 BNB Chain, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap LINK on OP Mainnet to ARB on BSC without KYC?
Requirements are checked for the live LINK OP Mainnet to ARB BSC 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.
