The type of coin rewards that an LP gives depends on the specific liquidity pool. Each pool has its own set of rules and rewards that are tailored to the specific asset and the liquidity provider. Generally, the rewards are a combination of transaction fees, block rewards, and/or a share of the pool’s profits. Generally, the more active a liquidity provider is in the pool, the higher the reward they will receive. It is important to research the specific pool and its rewards before investing in it.
