Non-Critical Issues

[N-1]: Function defines a named return variable but then it uses return statements

Context:

1. if (product1 == 0) return result = product0.div(divisor, roundUp); L185
2. if (value == type(uint256).max) return result = type(uint128).max; L70
3. return value1 < value2 ? value1 : value2; L89
4. return pools[strike][maturity].feeGrowth(); L119
5. return pools[strike][maturity].feesEarnedOf(owner); L124
6. return pools[strike][maturity].protocolFeesEarned(); L129
7. return mint(param, true, durationForward); L249
8. return burn(param, true, durationForward); L314
9. return deleverage(param, true, durationForward); L374
10. return leverage(param, true, durationForward); L427
11. return (pool.long0FeeGrowth, pool.long1FeeGrowth, pool.shortFeeGrowth); L67
12. return pool.liquidityPositions[owner].feesEarnedOf(pool.long0FeeGrowth, pool.long1FeeGrowth, pool.shortFeeGrowth); L76
13. return (pool.long0ProtocolFees, pool.long1ProtocolFees, pool.shortProtocolFees); L84

Recommendation:

Choose named return variable or return statement. It is unnecessary to use both.

[N-2]: Wrong order of functions

Context:

1. constructor() NoDelegateCall() { L77 (constructor can not go after private function)
2. function tokenByIndex(uint256 index) external view override returns (uint256) { L41 (external function can not go after public function)
3. mapping(bytes32 => uint96) private reentrancyGuards; L41 (state variable declaration can not go after constructor)
4. function positionOf(address owner, TimeswapV2TokenPosition calldata timeswapV2TokenPosition) public view returns (uint256 amount) { L66 (public function can not go after private function)
5. constructor() NoDelegateCall() { L65 (constructor can not go after private function)

Description:

According to official solidity documentation functions should be grouped according to their visibility and ordered:

• constructor

• receive function (if exists)

• fallback function (if exists)

• external

• public

• internal

• private

Within a grouping, place the view and pure functions last.

Recommendation:

Put the functions in the correct order according to the documentation.

[N-3]: NatSpec is missing
