LINK input identity and handling
Chainlink is classified as a governance or utility token for this route. LINK uses a network-specific contract asset on Optimism. The Optimism side is contract-tracked rather than a native gas balance. 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.
Leaving Optimism L2 for Polygon L1
Optimism inclusion and its ethereum settlement are distinct from final receipt on Polygon. The live route, rather than a generic rollup withdrawal assumption, determines the provider path and timing for this direction.
WBTC wrapped-token output check
WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. On this route WBTC is the destination token on Polygon. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Polygon destination execution
Polygon is a L1 EVM network in the Polygon ecosystem. POL pays destination-side network gas on Polygon. EVM 0x account address A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas.
WBTC output identity and receiving
Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Polygon. The recorded Polygon representation uses 8 decimal places. 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.
Optimism source execution
Optimism is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Optimism. EVM 0x account address 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.
EVM-to-EVM execution boundary
Optimism and Polygon can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories. The recorded settlement context includes ethereum, so L1 and L2 confirmation behavior should not be assumed identical.
Mistakes specific to LINK Optimism to WBTC Polygon
Route-specific mistakes include sending on a network other than Optimism; using a destination that is not valid for Polygon; running out of ETH before the source transaction is submitted; treating a wrapped token as the native gas asset. 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. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. 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.
