"Given current volumes, we expect the impact on UNI burn to be substantial." — Hayden Adams, Founder, Uniswap Labs (July 17, 2026)
Uniswap governance opened on-chain voting on July 19, 2026, for two proposals — Proposal 100 and Proposal 99 — that would activate protocol fees on select v4 pools across seven chains and extend v2/v3 fee collection to Robinhood Chain. As of late July, the votes show roughly 2.94 million UNI in favor, zero against, and a 40 million UNI quorum not yet met. The gap stands at approximately 37 million UNI — 92.6% of the threshold still outstanding.
The proposals represent the second phase of Uniswap's structural shift toward token-value accrual, following the December 2025 UNIfication overhaul that burned 100 million UNI ($596 million) and routed all protocol fees into a permanent burn mechanism. Monthly protocol fees have risen from roughly $3.1 million in February 2026 to approximately $5.1 million in June 2026 under v2/v3 collection alone. Adding v4 pools — which have processed over $110 billion in cumulative volume since their January 2025 launch — and Robinhood Chain, which generated $6 billion in swap volume in its first nine days, could meaningfully expand the burn rate. The vote closes July 26. If quorum fails, resubmission would restart a 6-to-10-week governance clock.
Two on-chain proposals are live on Uniswap governance, with voting running from July 19 through July 26, 2026.
Proposal 100 — "Activate v4 Protocol Fees (Part 1/2)" enables protocol fee collection on select Uniswap v4 pools across seven chains: Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism, and Robinhood Chain. The proposal covers three pool categories: static fee pools without hooks, continuous clearing auction (CCA) pools, and aggregator hook pools. A follow-up Part 2/2 proposal is expected for remaining v4 chains, as GovernorBravo imposes a ten-action limit per proposal.
Proposal 99 — "Protocol Fee Expansion: Robinhood Chain" extends existing v2 and v3 protocol-fee collection to Robinhood Chain, which launched on July 1, 2026, as a permissionless Ethereum L2 built on the Arbitrum stack.
A temperature check conducted July 7–12, 2026, passed with 93% support: 13.9 million UNI voted in favor versus approximately 1 million against. The on-chain vote requires 40 million UNI to reach quorum.
The v4 fee proposal introduces a tiered structure calibrated by pool type and chain:
Static-Fee and CCA Pools:
| LP Fee Tier | Protocol Fee | |---|---| | 5 basis points | 1.25 bp | | 30 basis points | 5 bp | | 83.34–100 bp | 10 bp (cap) |
Aggregator Hook Pools:
| Chain | Default | Selected Stablecoins | |---|---|---| | Non-Base chains | 10 bp | 3 bp | | Base | 3 bp | 1 bp |
Base receives preferential rates, reflecting its status as the highest-volume L2 for Uniswap. The fee structure maintains trader-facing fees unchanged — protocol fees are carved from the LP share, not added on top. This preserves price competitiveness while redirecting a portion of LP revenue to the burn mechanism.
Under v2, the protocol captures 0.05% from a total 0.30% swap fee (reducing the LP share to 0.25%). Under v3, the take rate varies: 25% of LP revenue on low-fee pools (0.01%–0.05% tiers) and 16.7% on high-volatility pools (0.30%–1.00% tiers).
The current fee proposals feed into the burn infrastructure established by the UNIfication vote, which passed on December 25, 2025, with 125.3 million UNI in favor and 742 against — 99.9% approval. Execution occurred on December 28, 2025, following a two-day timelock.
UNIfication created a two-contract system:
The December 2025 execution included a retroactive treasury burn of 100 million UNI — approximately 10% of total supply at that time, valued at $596 million based on a $5.96 average price. This one-time burn represented simulated buyback amounts from fees the protocol would have generated since inception.
Since December 2025, the ongoing burn mechanism has removed approximately 7.5 million UNI (~$25.6 million at ~$3.50/UNI) from circulation. The annualized ongoing burn rate runs at approximately 4–5 million UNI per year, or roughly 0.4% of supply annually. A record single-day burn of approximately 186,000 UNI occurred in June 2026.
Monthly protocol fees have tracked upward: roughly $3.1 million in February 2026, rising to approximately $5.1 million in June 2026 under v2/v3 collection on Ethereum, Optimism, Arbitrum, Base, Zora, and XLayer.
The Gauntlet risk analysis, commissioned by Uniswap governance, modeled the impact of protocol fees on liquidity and volume across fee scenarios.
At a 10% protocol fee (roughly consistent with the current v3 structure), the analysis projected:
The analysis found that core retail and institutional volume proves "relatively resilient" to fee activation, because Uniswap maintains price advantages despite reduced liquidity. Gauntlet noted that "liquidity is rarely a limiting factor" for most core users. MEV traders, by contrast, show linear sensitivity — volume losses track proportionally to liquidity reductions.
If Proposal 100 passes, the implied additional revenue from v4 pools could be material. Uniswap v4 has processed over $110 billion in cumulative volume since its January 31, 2025 launch. The protocol captures approximately 30% of all Uniswap trades, with v3 still handling 60%. Layer 2 networks account for 67% of v4 transaction volume.
At an average protocol fee of roughly 5 basis points on v4 volumes, and assuming $148 billion in 30-day Uniswap-wide volume (recent reported figure across 36 chains), the incremental annual protocol revenue from v4 alone could range from $27 million to $60 million, depending on v4's share of eligible volume. Combined with existing v2/v3 fees, total annualized protocol revenue could approach $80 million–$120 million.
Robinhood Chain's launch on July 1, 2026, has generated volumes that alter the fee calculus significantly. In its first week, the chain processed $3.1 billion in DEX volume. By July 10 — nine days in — cumulative swap volume reached $6 billion. On a single day, July 8, the chain recorded $563.9 million in Uniswap trading volume.
According to Hayden Adams, 99.5% of DEX volume on Robinhood Chain comes through Uniswap. The chain briefly flipped Hyperliquid in 24-hour DEX volume and climbed into the top five chains by DEX activity, according to a Bernstein analysis published July 13.
Extrapolating the first ten days' performance to a full month suggests over $20 billion in monthly volume. At an average protocol fee of approximately 5 basis points, that implies over $10 million in monthly protocol revenue from Robinhood Chain alone — a figure that would nearly double the June 2026 all-chain fee total.
However, the data warrants caution. Bernstein noted that the chain's initial week was driven by "speculative demand for memecoins." Sustainability of these volumes is unproven. TVL on Robinhood Chain reached approximately $500 million, with Uniswap holding $44.87 million and Morpho's lending protocol accounting for roughly $90 million. Whether professional liquidity follows speculative volume will determine whether the revenue projection holds.
An academic paper published on arXiv in July 2026 — "Causal Effects of Protocol-Fee Changes on Liquidity Provision in Automated Market Makers" — provides the first rigorous empirical analysis of the December 2025 fee switch's impact on LPs.
The study used a matched-overlap event-study difference-in-differences design across 779 treated pools and 303 controls, analyzing 17,598 pool-weeks. The pre-period spanned January 2024 through November 2025, with an 8-week post-period window around activation.
The central finding: no large short-run average response in active liquidity or local depth following the fee switch. Time-weighted active liquidity showed a confidence interval of [-1.11, 0.33] on the inverse-hyperbolic-sine scale. Local depth (±2%) showed [-2.02, 1.27]. LP participation and composition showed no detectable response.
The authors characterize this as "non-detection at the design's resolution rather than a precise zero." Joint lead tests did not reject parallel pre-trends. The results held across entropy balancing robustness checks and caliper sensitivity analysis.
This finding is significant for the v4 vote: it suggests that activating protocol fees on v4 pools is unlikely to trigger a mass LP exodus in the short run, consistent with Gauntlet's modeling. However, the paper explicitly notes its estimates constrain only short-run LP exit margins, not long-run elasticity or total welfare effects.
The most immediate risk to the proposals is quorum failure. As of the latest available tally, both Proposal 99 and Proposal 100 show approximately 2.94 million UNI in favor and zero against — 7.4% of the 40 million UNI threshold.
This is not unusual for Uniswap governance. The quorum bar was set to prevent capture by small token-holder groups, but it creates a participation challenge. The UNIfication vote cleared the threshold comfortably with 125.3 million UNI voting. Whether fee-expansion proposals generate similar urgency is uncertain.
If quorum is not met by July 26, the proposals expire with no on-chain effect. Resubmission would restart the governance clock — temperature check, on-chain vote, timelock — a process estimated at 6–10 weeks minimum.
If quorum passes, a mandatory two-day timelock precedes automatic on-chain execution across seven chains via retryable tickets on Arbitrum Orbit chains. The Part 2/2 proposal for remaining v4 chains would follow separately.
UNI trades at approximately $3.53 as of July 19, 2026, with a market cap of roughly $2.12 billion. The revenue multiple, based on current annualized fees of approximately $50–60 million, sits at roughly 35–42x — significantly compressed from the 207x multiple calculated at UNIfication launch, reflecting both revenue growth and token price decline from the $5.96 level at the December 2025 burn.
The v4 fee vote tests whether Uniswap's burn-for-value model can scale. The December 2025 UNIfication vote proved that the mechanism works at a technical level — fees flow to TokenJar, UNI gets destroyed in Firepit, supply contracts. Monthly fee revenue has grown 64% from February to June 2026 under v2/v3 alone.
The v4 expansion would extend this to $110 billion in cumulative volume across seven chains. Robinhood Chain's $6 billion in nine-day volume adds a wild card — high potential revenue, unclear sustainability. Academic evidence from a July 2026 arXiv paper suggests LPs do not exit en masse when fees activate, which removes one objection to expansion.
The binding constraint is governance participation. At 7.4% of quorum with days remaining, the 40 million UNI threshold is the real test — not whether fees work, but whether enough token holders care to vote. Uniswap has transformed from a governance token with no cash flows to a protocol with a functioning deflationary mechanism. Whether the market prices that transformation depends on whether Proposal 100 executes on July 28 — or gets pushed back to Q4.
