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 Scroll as LINK?
LINK is a contract representation on Scroll at 0x548c6944cba02b9d1c0570102c89de64d258d3ac. ETH, not LINK, pays gas unless both symbols are the same. A Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll. 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 Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll. 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 Scroll, 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 Scroll without KYC?
Requirements are checked for the live OP OP Mainnet to LINK Scroll 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.
