Users can later redeem these tokens for their share of the underlying assets plus any accrued fees from trades executed within the pool.Additionally, liquidity tokens often enable users to engage in farming or staking activities. By locking up these tokens, users can earn rewards, further incentivizing participation in liquidity provision.Overall, liquidity tokens play a crucial role in enhancing trading efficiency and liquidity in decentralized finance platforms. They allow users to contribute to the overall health of the trading ecosystem while also offering them opportunities for earning additional returns.
