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 Avalanche as WBTC?
WBTC is a contract representation on Avalanche with 8 decimals at 0x50b7545627a5162F82A992c33b87aDc75187B218. AVAX, not WBTC, pays gas unless both symbols are the same. An Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain contract. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
Why does the LINK to WBTC 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, WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
What changes between the source and destination asset roles?
LINK is the deposited token input; WBTC is the quoted wrapped-asset 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 Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain contract. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
Can the wrapped asset pay native network gas?
No. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path. 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 Avalanche destination must be a C-Chain-compatible account; native AVAX can fund later C-Chain gas, while token receipt uses the quoted C-Chain 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 WBTC on Avalanche without KYC?
Requirements are checked for the live LINK OP Mainnet to WBTC Avalanche 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.
