# Fees

NEST is a DEX aggregator where trading operations are executed through the Ston.fi and Dedust.io exchanges.

When performing swaps (buying or selling tokens) via the NEST platform, a gas fee is charged, determined by the validators and the price of TON.

Additionally, a transaction fee is applied depending on the liquidity pool used:

* DeDust.io pool: 0.25%
* Ston.fi pool: 0.3%

These fees are approximate and may vary depending on the trading pair and the fee structures set by DeDust.io and Ston.fi exchanges.

The NEST platform itself charges a 0.25% fee for each swap (buy or sell).
