PlusPool

 This contract manages the leveraged assets of KLAYswap's plus pool liquidity providers. Liquidity providers can maximize their returns with positive assets (deposited assets + utilized assets) by using positive deposits according to their deposited assets. However, a high asset utilization ratio can result in automatic returns, which can result in losses.

liquidationFactor
automatic return factor
It is a value between 1 and 10^18, in units of 0.000000000000000001%
Default - 850000000000000000
borrowFactor
Utilization cost interest rate of utilized assets

liquidationCount
function liquidationCount(address user) public view returns (uint)
Returns the user's cumulative automatic return count
State-Changing Functions
claimReward
function claimReward() public
Method that a user calls to claim the claimable KSP that has accumulated for the pair
When called, KSP is claimed from the Factory and paid to msg.sender
Even if the method is not called directly, it is automatically called when the LP token balance of the user’s wallet changes.
When liquidity is added
When liquidity is removed
​
openPosition
function openPosition(uint amountA, uint amountB, uint borrowA, uint borrowB, uint minAmountLP) public payable
Method that depositing to PlusPool
If the token to deposit is KLAY, msg.value is provided.
After liquidity is provided, the LP token corresponding to the pool share is minted in the msg.sender wallet.
If there is claimable KSP when called, the claim proceeds to msg.sender.
Parameter
amountA : The deposit amount of tokenA
amountB : The deposit amount of tokenB
borrowA : The utilization amount of tokenA
borrowB: The utilization amount of tokenB
minAmountLP : Minimum Guaranteed LP amount
closePosition
function closePosition(uint amountLP, uint minAmountA, uint minAmountB) public
Returns the amount of LP tokens, and distributes the corresponding tokenA and tokenB to the msg.sender wallet
The returned LP token amount is burned
If there is claimable KSP and Airdrop when called, the claim proceeds to msg.sender.
Parameters
amountLP:  The amount of LP tokens burned due to liquidity removal
minAmountA : The withdraw amount of tokenA
minAmountB : The withdraw amount of tokenB
