The LP reward refers to the liquidity provider reward. For example, suppose you add Hive and HBD tokens of equal value to the Hive/HBD liquidity pool. If that pool distributes LP rewards, you will start earning rewards periodically. Cent has more than ten liquidity pools. We continue to distribute rewards regularly. You can access Cent's liquidity pools at the following addresses:
