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 Ethereum as USDC?
USDC is a contract representation on Ethereum at 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48. ETH, not USDC, 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. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Why does the LINK to USDC 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, The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
What changes between the source and destination asset roles?
LINK is the deposited token input; USDC is the quoted stablecoin 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. 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. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Which stablecoin contract must this route match?
USDC must match the quoted Ethereum representation. A ticker or target price is not enough to identify a token contract.
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.
Can I swap LINK on OP Mainnet to USDC on Ethereum without KYC?
Requirements are checked for the live LINK OP Mainnet to USDC 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.
