3 variable AMM

Timeswap works on a unique 3 variable constant product equation where interest rates & collateral factors are all market-driven and there is no dependency on oracles & liquidators. 
This makes us a complete self-sufficient protocol that is fully permissionless & oracle-less. Anybody can create a pool with any ERC20 token as collateral & any other ERC20 token as an asset being lent/borrowed.
Inspired from Uniswap's constant product equation, Timeswap works on a 3 variable constant product formula-
                                                   X×Y×Z=KX\times Y\times Z=KX×Y×Z=K
 
​X=X=X=
 Principal Pool is a virtual pool and is equal to the amount of assets in the pool that can be borrowed. It's equal to the sum of the assets deposited by the lenders 
​Y=Y=Y=
 Interest Rate Pool is a virtual pool that determines the interest amount per second of the pool, such that ratio YX\frac{Y}{X}XY​
 is the per second average interest rate for the duration of the transaction to the maturity of the pool.
​Z=Z=Z=
 Collateral Factor Pool is a virtual pool that determines the collateral to be locked by the borrowers such that ratio XZ\frac{X}{Z}ZX​
 is the average collateral factor. It's used to calculate the expected average loan to value at the time of the transaction 
​K=K=K=
 Invariance Constant product
Additionally, there are two other pools :
​C=C=C=
Collateral Locked Pool and is equal to the amount of ERC20 collateral tokens locked in the pool by borrowers
​A=A = A=
Asset Pool and is equal to the amount of ERC20 asset tokens locked in the pool. It is the sum of assets lent by lenders & the debt paid by the borrowers 
While interacting with the pools, Lenders & Borrowers change the variables such that constant product is always maintained. Lending more assets into the asset pool decreases the interest & Collateral value to be locked, whereas, borrowing more assets from the asset pool increases the interest & Collateral value to be locked.
