The current pools on STONfi clearly demonstrate that instruments with the same format can have completely different capabilities within a single exchange on the $TON network. Here are these pools:

FRT/TON with an APR of 140% is a farming pool where, in addition to the usual APR, we will also receive an additional reward as a bonus for providing liquidity.

STON/USDT with an APR of 17% stands out from other pairs due to its interesting feature. The pair has protection against impermanent loss, and the pool itself has infinite farming status. This makes it appear to be a more stable instrument without any time limits.

TONG/TON with an APR of 177% also operates in a farming format. The high APR here is supported by steady demand and constant user participation, as well as the fact that this pair has been around for a very long time and has had a high APR for a very long time, so most people, when they see a new pair or this one, choose this one because it has been proven over time.
