settlePosition

function settlePosition(
    address[] memory _path,
    uint16 _underlyingAssetIndex,
    uint256 _optionTokenId,
    uint256 _minOutWhenSwap,
    bool _withdrawETH
) external returns (uint256)

• Settles a single option position

• Handles token swaps and settlement calculations

• Returns the amount received from settlement

settlePositions

function settlePositions(
    address[][] memory _paths,
    uint16 _underlyingAssetIndex,
    uint256[] memory _optionTokenIds,
    uint256[] memory _minOutWhenSwaps,
    bool _withdrawETH
) external

• Settles multiple option positions in a single transaction

• Batch processes settlements for efficiency

• Handles multiple token swaps and settlements
