Fee Switches and Protocol Revenue

A decentralized exchange charges traders a small fee on every swap. Where does that money go? By default, almost always to the liquidity providers who supplied the assets being traded — it's their compensation for bearing impermanent loss. But most protocols are built with a fee switch: a governance-controlled parameter that can redirect a slice of that fee stream elsewhere, typically to the protocol's treasury or to holders of its governance token. Whether that switch is on, off, or somewhere in between is one of the most consequential — and most contested — decisions in a protocol's governance.

Two claims on the same fee

Every swap on an automated market maker pays a fee, commonly around 0.3% of the trade, taken out of the swap itself. Ordinarily, 100% of that fee accrues to the liquidity providers, added to the pool as a reward on top of whatever they can withdraw. A fee switch splits that fee: a portion (say 1/5 or 1/6 of the total) is instead diverted to a separate address controlled by the protocol's governance, leaving LPs with the rest.

Worked example

A pool generates $10 million in trading fees over a year with the fee switch off; liquidity providers keep all $10 million, on top of whatever price impact they absorbed as impermanent loss. Governance votes to turn the switch on, diverting 1/6 of fees to the treasury. Same trading volume, same $10 million in gross fees: LPs now receive roughly $8.33 million (5/6), and $1.67 million (1/6) flows to the protocol treasury, which governance can then distribute to token holders, use for buybacks, or hold as a reserve. If, after the switch turns on, some LPs decide the reduced yield no longer compensates them for impermanent loss and withdraw liquidity, the pool's depth falls, spreads widen, and trading volume itself may decline — meaning the treasury's 1/6 could end up being 1/6 of a smaller number, not a free $1.67 million pickup.

What this means in practice

A fee switch decision is really a question about who the protocol exists to serve: liquidity providers, whose capital makes the exchange function at all, or token holders, who often did not supply any liquidity but hold governance rights. Protocols that turn the switch on are effectively declaring the token a claim on cash flow, which has real consequences for how the token should be valued — closer to a dividend-paying equity than a pure utility or governance instrument — and can trigger regulatory scrutiny that a purely-utility token avoided.
