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 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. 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 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. 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 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 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.
Can I swap LINK on Base to WBTC on Avalanche without KYC?
Requirements are checked for the live LINK Base 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.
