When a swap is executed through STONfi, fees are applied at the pool level rather than at a single global step. Each pool along the chosen route charges its own fee on the incoming trade, adds that fee to its reserves and passes the remaining amount further.

The effective fee for the user is therefore the sum of all pool level fees along the route. Because Omniston sees the entire path, it can take these per pool fees into account when comparing candidate routes. A path with more hops is not always worse, but it must compensate for extra fees with better prices or deeper liquidity. STONfi’s routing logic relies on this detailed view to avoid routes that look good on price alone but lose too much to cumulative fees.

For liquidity providers, this design means that every pool they participate in collects fees independently. Even if a swap is split across several pools, each portion contributes to the fee income of the corresponding pool, and that income is reflected in the share value of providers in those pools. $TON $DOGS
