Fei Protocol has a staking pools in which TRIBE is earned over time.
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.
Fei Protocol staking allows users to deposit multiple tokens to earn TRIBE. Each pool has an allocation of the overall staking rewards. The rewards for each pool are split evenly amongst 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. Optional lockups which earn higher rewards may be introduced in the future.
Users are currently staking FEI/TRIBE Uniswap v2 LP tokens as well as FEI+3CRV tokens to earn the TRIBE rewards. The Fei DAO can adjust the distribution rate and the staked token.
Fei Protocol uses the TribalChief staking contract, which is a fork of SushiSwaps MasterChef contract.
