# Mint Fee Sharing

[Mint fee](https://docs.symfi.io/sym-finance/mechanism/symtoken-minting-module/mint-fee) from leverage buyers accumulates in the mint fee pool. For each Token swapped, the LP gets **1 pool share**, which can be used to claim proportionate mint fee from the mint fee pool.

### Vesting and decay

When distributed to LPs, pool shares are **locked**. The balance of locked pool shares has a daily decay of 5%. LPs need to stake symToken to stop the decay and vest locked pool shares into liquid pool shares. For each pool share to be fully vested, 1 symToken need to be staked for 14 days. Once equivalent amount of symToken is staked, pool shares stop decaying.
