Liquidity pools are a means to provide funds for Swap on DEX. Liquidity providers provide liquidity to the pool, and are rewarded with a share of each swap. For example, to provide liquidity to STON.fi and get access to high APR you need to go to the Pools tab on their website and select a pool based on APR and coin pairs. Next you need to prepare the coins in price equivalent and on the pool page click on Add liquidity. For some pairs, there is a provision to lock LP tokens for additional rewards. On STON.fi, liquidity providers share 0.2% of each swap. This results in high APRs on STON.fi, for example:
HMSTR/$NOT , APR - 687%
