Uniswap fee expansion: what changes, and why it matters

A snapshot vote is underway that would broaden Uniswap’s protocol fee framework beyond the subsets already charged, bringing fees to the remaining v3 liquidity pools and activating collections on eight more networks. This proposal also introduces a new, tier-based fee adapter to apply fees automatically according to each pool’s fee tier.

The governance route for this move uses the recently adopted UNIfication process, which compresses the timeline for parameter changes: a short Snapshot vote followed by onchain execution through timelocked transactions. That faster path removes the prior multi-stage request-for-comment step and aims to make fee adjustments more responsive.

Operationally, fees on Layer 2 networks would be routed into chain-specific TokenJar contracts and then transferred back to Ethereum mainnet to be processed by a centralized burn contract, the Firepit. Mainnet collections go straight into that burning mechanism, converting diverse token fees into permanent UNI supply reduction.

The proposal names the target chains explicitly: Arbitrum, Base, Celo, OP Mainnet, Soneium, X Layer, Worldchain, and Zora. Because governance contract constraints require parallel onchain actions, passing the vote would spawn two simultaneous onchain proposals that split the work across networks.

Uniswap’s team and community point to the December activation on selected pools as a trial run: market-adjusted TVL on mainnet held up and the automated burn flow operated without major incidents. Meanwhile, Uniswap continues to evolve other product pieces, like introducing Continuous Clearing Auctions and enabling institutional onchain trading for tokenized assets.

• New fee scope: expand to all remaining v3 pools and v2 on targeted chains.
• Governance cadence: five-day Snapshot vote, then timelocked execution.
• Cross-chain burn path: TokenJar bridge → Firepit burn on mainnet.

If governance approves, the change marks a structural shift in how Uniswap captures protocol-level revenue: instead of a curated list of fee-bearing pools, fee capture becomes systematic and tier-driven across the v3 surface. That will change incentives for liquidity providers and could alter fee economics across the platform.
