# What is YALE?

RFV description.

**YALE stands for Yieldzard Auto-Liquidity Engine which is the base of our protocol and is of major importance for the entire Yieldzard Ecosystem, it plays a critical role in allowing the buy & sell of $YLZ tokens on PancakeSwap.**

In simple terms, think of Liquidity as a huge pool of money that is being split 50/50 between $YLZ tokens on one side and $BNB tokens on the other side. There is a conversion ratio that is set to the amount of $YLZ you can get with BNB, for example, 1 BNB = 14.77 YLZ.

The ratio above will change at the time a transaction will occur, when for example somebody buys YLZ, the price per one $YLZ token will go up. The same goes in the opposite direction for sells.

Liquidity allows for anybody to buy & sell their YLZ/BNB at any time, however, the less money/liquidity there is in the pool, the worse price you get so what our Yieldzard Auto-Liquidity Engine (YALE) does, is add more liquidity to that pool by itself and therefore, solving that issue.

Every 48 hours, our Yieldzard Auto-Liquidity Engine (YALE) will inject automatic liquidity into the market. On each buy or sell order, there is a **4% tax fee** that automatically gets stored into an Auto-LP wallet and built into our protocol's smart contract is the mechanism that smartly takes the 50% of the amount of YLZ stored in the wallet, and will **automatically** buy BNB at the current market price.

The remaining 50% of Yieldzard in the Auto-LP wallet will be used for the YLZ side of liquidity, therefore, giving equal an 50/50 weighting of YLZ/BNB which will then be **automatically** added as new, additional liquidity into the market pair and raising the amount of liquidity in the pool.

The Yieldzard Auto-Liquidity Engine will do this **every 48 hours** by adding more and more liquidity to the pool which will allow $YLZ token holders to easily sell their tokens at any time with little to no market slippage. It will also aid in **maintaining protocol stability** to make sure the APY is upheld for the entire life of Yieldzard.
