# Possible ways to decrease sLoC
https://docs.google.com/spreadsheets/d/1mony_HT_f9wTgxj-9YPh53P-7lydr5LRhB0O3iy5y8A/edit?usp=sharing
##  v2-library
- Remove types, use a common library for checks
- Reuse an existing dpeloyed library for uint256 math operations
- Use [OZ's ownable implementation](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/access/Ownable.sol)
- Use [OZ's IERC20](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/IERC20.sol)

## v2-option
- Change `process` architectur eto be more sLoC efficient?
- Existing contract maybe used for no delegate call
- Using bytes for params?
- Reduce no of line in `structs/Option.sol` 
- Use numbers instead of enums

## v2-pool
- Use bytes for events
- removing functions that are not used in`ConstantSum.sol` and `ConstantProduct.sol` 


## ToDo List
[ ] Remove `LendGivenPosition`, `CloseLendGivenPrincipal`, `CloseBorrowGivenPrincipal`
[ ] Tweak the linter
[ ] Remove unused imports

[ ] Remove types where its not required
[ ] Remove `Math.sol`
[ ] Removing some errors


[ ] Remove code apart from mulDiv in `FullMath.sol`
[ ] Optimising if-else condition in the periphery
[ ] Add strike conversion utility functions
[ ] Utilise boolean in mulDivUp/mulDivDown => mulDiv(up=true)
[ ] Optimise `CalculateSwap.sol`
[ ] Refactor natives


[ ] Remove enums, replace with uint
[ ] Double check for dead code in `ConstantSum.sol` and `ConstantProduct.sol`
[ ] Experiment with Pool key
[ ] Pass by value only without key
[ ] Use bytes for event param
