Where Do DEX Trading Fees Actually Go?
A swap fee is small on screen, but it is part of the economic machinery behind a decentralised market.

Liquidity providers place assets into pools and expose themselves to price movement and other risks. Trading fees are one mechanism used to compensate liquidity provision.
Fees can be split
Depending on the DEX and pool design, part of a swap fee may accrue to liquidity providers and another part may go to a protocol, treasury or other destination. There is no universal split across all decentralised exchanges.
The fee is separate from network cost
The swap fee charged by the trading venue is not the same thing as the blockchain network fee paid to process the transaction. A single swap can involve both.
High volume changes the economics
A small percentage fee can become meaningful when a pool handles substantial volume. But fee income is not guaranteed profit: liquidity providers also face changing asset prices, impermanent loss and smart-contract/platform risk.
A fee is part of the market design
DEX swaps are not normally free. A pool or protocol applies a trading fee, usually as a small percentage of the swap. Depending on the design, some can accrue to liquidity providers, some can go to the protocol or other configured destinations, and network fees are separate again. The exact split is protocol-specific, so “the fee goes to LPs” is too simplistic as a universal rule.
Why this matters to liquidity providers
Fees are one reason somebody might provide assets to a pool: active trading can generate fee income. But that does not turn LP positions into guaranteed yield. The values of the two assets can move, the composition of the position changes as people trade, and impermanent loss can outweigh fees. When I think about a pool now, I separate three things: trading fees, changes in asset prices, and changes in the quantities of each asset held by the position.
Creating the GRIFF/SOL pool made me realise that “the fee” is not one universal crypto charge. The pool’s trading fee and Solana’s transaction cost exist for different reasons.
