Hayden Adams Dismisses Claims of Lowered Uniswap v4 Liquidity Earnings

The governance vote, which secured 46.6 million UNI in support, activated a fee-controller system across seven chains, including Ethereum, Arbitrum, and Base. Critics had suggested the change would siphon up to 25% of liquidity provider (LP) profits. Adams countered this by citing a 30-basis-point pool example: while traders now pay a combined fee near 35 basis points, the 30-basis-point portion designated for LPs remains untouched, with the new protocol charge representing only 14% of the total transaction cost.

Technical documentation for v4 supports this distinction, as the protocol calculates the new charge separately from the LP fee. Despite this, some industry participants remain skeptical. Panoptic founder Guillaume Lambert previously warned that such charges could drive capital toward competing automated market makers, particularly if the fees are applied without regard for the profitability of individual LP positions. Uniswap Labs, however, pointed to historical data from v2 and v3, noting that previous fee activations did not trigger significant liquidity exits, with the largest v3 pools retaining 98.5% of their assets.

Collected fees are routed to TokenJar contracts, with assets linked to the protocol’s Firepit mechanism for UNI burns. While the current proposal covers the initial set of v4 deployments, additional chains like Celo and Zora await a future governance vote. The long-term impact on liquidity remains the primary metric for the community, as the protocol retains the flexibility to adjust rates or override rules if the current model faces resistance from market participants.
