Protocol Fee Configuration
Review protocol fee splits for Uniswap v2 and Uniswap v3 fee tiers in the current rollout.
Protocol fees are a portion of swap fees routed to protocol-controlled collection contracts instead of LPs. They are distinct from LP swap fees and are governance-configurable.
Swap Fees and Protocol Fees
- Swap fee: charged on every trade and distributed to LPs based on active liquidity.
- Protocol fee: a portion of the swap fee redirected to protocol fee collection contracts.
In the current rollout, protocol fees are active on all Uniswap v2 pools and selected Uniswap v3 pools. Additional adapter flows can be enabled through governance.
Fee Split Table
| Version | Fee tier | LP fee | Protocol fee |
|---|---|---|---|
| v2 | All pools | 0.25% | 0.05% |
| v3 | 0.01% | 0.0075% | 0.0025% |
| v3 | 0.05% | 0.0375% | 0.0125% |
| v3 | 0.30% | 0.25% | 0.05% |
| v3 | 1.00% | 0.8334% | 0.1666% |
How Configuration Is Enabled
- Uniswap v2: protocol fees are enabled or disabled globally by setting
feeToon the v2 factory through governance. When enabled, the protocol fee rate is fixed in pair contracts at1/6of the swap fee (0.05%of the0.30% total). - Uniswap v3: protocol fee configuration is applied to selected pools via governance-controlled configuration flows.
- Uniswap v4 adapters: part of the broader protocol-fees architecture and can be enabled through governance.
A full list of v3 pools in the initial rollout is available here. For a broader conceptual overview of fees across protocol versions, see Fees.
Collection and Conversion
Collected protocol fees accumulate in onchain collection contracts. Participants can submit release transactions with their signer to burn a required UNI amount and claim configured assets based on current contract state.
