Fei Protocol has a staking pool in which FEI/TRIBE Uniswap LP tokens are deposited and TRIBE is earned over time.
As of FIP-2, the total reward balance is 200,000,000 TRIBE, distributed over 2 years. This represents 20% of the initial TRIBE supply. The rewards distribution rate decreases linearly.
Distribution is gated by the FeiRewardsDistributor. It calculates the amount which should be released at any given time and drips it to FeiStakingRewards weekly.
Fei Protocol staking allows users to earn TRIBE tokens while providing liquidity for TRIBE. This is commonly referred to as a Pool 2 in terms of yield farming.
The rewards are split evenly among all participants at any given time. Staking is completely fluid. Users can deposit liquidity assets (stake), earn TRIBE for a few blocks, claim earned TRIBE, then withdraw staked tokens at will. There are no lockups on staked tokens.
Users are staking FEI/TRIBE Uniswap v2 LP tokens to earn the TRIBE rewards. The Fei DAO can adjust the distribution rate and the staked token if the need arises.
