If you open the liquidity pools on STONfi and just look at the numbers, you can see how the APR values for some pairs have changed recently. I periodically monitor the pools on the $TON network and remember well what the indicators were before, so such changes are immediately noticeable.

TRAIN/USDT, APR ~171%. The indicator was lower before, and the current value stands out significantly compared to previous weeks.

XAUt0/TON, APR ~86%. The pair has been holding in this range for some time without any sharp jumps, and I think it will remain at the same level.

WOOF/TON, APR ~84%. For this pair, the current value is higher than before, which is why it has become more common when viewing the list of pools.

This is why liquidity pools are one of the most convenient DeFi tools, as it is enough to remember a few pairs, remember their APR, and after a while, know whether the pool has become more active.
