Uniswap founder Hayden Adams has proposed activating protocol-level fees on v4 deployments across Ethereum and several layer-2 networks, putting the long-debated fee switch to a tokenholder vote on the protocol's most recent architecture for the first time.

The proposal, first reported by TradingView, targets Uniswap v4 instances running on Ethereum mainnet and the layer-2 chains where v4 has shipped. If approved, it would route a defined share of swap volume to the DAO treasury rather than the current arrangement, in which liquidity providers collect the full fee at the pool level.

What does the v4 proposal cover?

Uniswap v4 introduced singleton contracts and a hooks-based extension layer, replacing the per-factory deployment model used in v3. The protocol version went live on Ethereum mainnet in early 2025 and has since rolled out to networks including Arbitrum, Optimism, Polygon, BNB Chain and Base.

Under the proposal's structure, fees would be collected at the v4 PoolManager singleton before reaching liquidity providers, leaving LP economics nominally unchanged while introducing a treasury-directed take on top. The cross-network framing addresses a recurring governance concern: piecemeal activation creates competitive arbitrage against whichever chain is left without a fee, since swap flow migrates to forks where capture is lowest. Activating across networks simultaneously closes that window.

Why does cross-network activation matter?

Treasury capture at the protocol layer has been a structural revenue question for Uniswap since the DAO restructured its treasury framework in 2023. Analysts and forum participants have modelled revenue impact at modest basis-point settings on Ethereum mainnet alone in the tens of millions of dollars annually; the v4 footprint adds layer-2 volume that, by some estimates, now accounts for a majority of the protocol's swap flow.

For liquidity providers, the operational consequence is a reduction in reported pool APR by exactly the protocol-fee increment. For tokenholders, the proposal introduces a recurring revenue stream that future governance measures could redirect to buybacks, grants or validator incentives. For competing forks, it removes one of the most-cited justifications for routing volume elsewhere.

What is the governance path?

The proposal must clear the standard Uniswap governance lifecycle: a temperature check on Snapshot, an on-chain vote through the protocol's Governor Bravo contract or its v4 successor, and a quorum threshold based on circulating UNI supply. Earlier fee-switch attempts on v3 did not reach the required quorum or were deferred over competitive concerns in 2024; Adams's cross-network framing is the first to position activation as a v4-specific question.

A community forum thread and accompanying temperature check typically precede the formal vote. The TradingView-linked coverage did not specify a vote commencement date. Under current governance parameters, the on-chain vote would impose a seven-day delay followed by a seven-day voting window. Approval would convert Uniswap from a zero-fee protocol to a treasury-capturing one on every deployed v4 network, with downstream consequences for delegation economics, grants programmes and the protocol's positioning against zero-fee forks running on the same chains.
