# Information of LF Coin

This is how to consider the information of LF coin, especially the value of LF coin. The following illustrates the flowchart to mint LF coin from a pair of two coins.

Relationship among token pair, pool coin, and LF coin

First, the following parameters should be known.

**PoolReserveA**- Amount of A coins in the pool

**PoolReserveB**- Amount of B coins in the pool

**PoolCoinSupply**- Amount of minted pool coins of a given pool
- Denomination of pool coin in Crescent is
`pool`

+ pool id value, e.g.,`pool35`

is the denom of pool coin of Pool 35

**PoolCoinFarmingAmount**- Amount of liquidfarmed pool coins of a given pool

**LFCoinSupply**- Amount of minted LF coin for a given pool
- Denomination of LF coin in Crescent is
`lf`

+ pool id value, e.g.,`lf35`

is the denom of LF coin of Pool 35

The above parameters can be queried from

`liquidity`

and `liquidfarming`

modules in Crescent. With the above parameters, the values below can be calculated.

How many pool coins equal to 1 LF coin is the same as

`BurnRate`

, which is computed as

$BurnRate = \frac{PoolCoin Farming Amount - Compounding Rewards}{LF Coin Supply}$

,where

`CompundingRewards`

denotes the amount of pool coins obtained from the last rewards auction. At the very beginning of liquidfarming, 1 LF coin is equal to 1 pool coin. As time goes by, 1 LF coin is equal to N pool coin, where N keeps increasing. How many (A, B) coin pair equal to 1 pool coin can be calculated as below.

$1 Pool Coin = \left(\frac{PoolReserveA}{PoolCoinSupply} CoinA, \frac{PoolReserveB}{PoolCoinSupply} CoinB \right)$
