Liquidity pools are a multifaceted tool that benefits all participants in decentralized swap. Yes, liquidity pools are primarily sources of tokens for swap, but on the other side of this process there are liquidity providers, and they supply liquidity for a reason.

A small part of the swap volume is shared between liquidity providers, but if the volume of swaps is large, this share can provide a good APR. For example on the $TON blockchain the main DEX is STON.fi, and active liquidity pools provide the following APR:
$PX/TON, APR: 66.05%
#FPIBANK /TON, APR: 108%
$HMSTR/TON, APR: 3.54%

Hamster Kombat stands out with a low APR. These are situations where volumes are insufficient to maintain APR. In such cases, some liquidity pools on STON.fi implement farming, where a certain fixed award is distributed daily, which ensures TVL even at low volumes. Thanks to this system, the following APR values are achieved:
$TADA/TON, APR: 492%
$T4U/TON, APR: 887%
$JETTON/TON, APR: 53%
