Uniswap launches eight-chain fee sharing voting, UNI token monthly earnings could significantly double

Since February 27, 2026, the Uniswap community has been conducting a final vote on activating the protocol fee switch on eight Layer 2 blockchains—Base, Arbitrum, OP Mainnet, World Chain, X Layer, Celo, Soneium, and Zora. The proposal aims to allocate at least one-sixth of the transaction fees into a “Token Jar,” which UNI holders can burn tokens to claim. The final voting will conclude on March 4.

Proposal Details: Fee Switch on Eight Chains and Revenue Multiplication Path

The core of this proposal is to officially activate the Uniswap fee switch mechanism on Base, Arbitrum, OP Mainnet, World Chain, X Layer, Celo, Soneium, and Zora. Specifically, at least one-sixth of liquidity providers’ fee income will be transferred into the Token Jar. UNI holders can choose to burn equivalent UNI tokens to receive this portion of the revenue, creating both a yield for token holders and reducing UNI circulating supply.

Since late December 2024, fee-sharing mechanisms have been enabled on Ethereum mainnet’s v2 pools and some v3 pools. According to DefiLlama, this has generated approximately $3.3 million in revenue so far. The proposal also plans to activate fee mechanisms on remaining Ethereum v3 pools, potentially doubling the related income.

Notably, since January 1, 2026, Base has surpassed Ethereum as the blockchain with the highest Uniswap fee revenue—users paid $55 million on Base across four versions, compared to $37 million on Ethereum during the same period.

UNI Market Performance and UNIfication Policy Background

This multi-chain voting has impacted UNI’s market. Over the past week, UNI rose about 9%, outperforming Bitcoin (-3.5%) and Ethereum (-2.4%). Uniswap founder Hayden Adams posted on X that the first phase of the Ethereum fee switch rollout has gone smoothly, with user deposits growing after market adjustments, and the token burn mechanism operating efficiently.

However, the market cap loss since the UNIfication proposal was introduced in November last year has not been fully recovered—UNI has fallen 59%, with the current trading price around $3.74.

Key Figures for This Vote

• Number of chains involved: 8 Layer 2s (Base, Arbitrum, OP Mainnet, World Chain, X Layer, Celo, Soneium, Zora)
• Fee distribution ratio: At least one-sixth of liquidity provider fees transferred to the Token Jar
• Total revenue since: Approximately $3.3 million generated on Ethereum mainnet since late December 2024
• Voting deadline: March 4, 2026
• UNI 7-day increase: +9% (compared to BTC -3.5%, ETH -2.4%)

Frequently Asked Questions

How does the Uniswap “Fee Switch” mechanism work?

Once activated, at least one-sixth of transaction fees will be diverted from liquidity providers into the Token Jar. UNI holders can choose to burn equivalent UNI tokens to claim the accumulated fees. This mechanism also reduces UNI circulating supply, potentially supporting the token’s value.

Why focus on Layer 2 chains instead of Ethereum mainnet?

Since January 2026, Base has surpassed Ethereum mainnet as the highest revenue-generating chain for Uniswap, indicating a large shift of DeFi activity to Layer 2s. Activating fee mechanisms across these eight Layer 2s helps capture the protocol’s true earnings more comprehensively and aligns with the current multi-chain ecosystem development.

If the proposal passes, what kind of returns can UNI holders expect?

Based on current data, the $3.3 million accumulated on Ethereum mainnet since the fee mechanism started could potentially double monthly after expanding to remaining v3 pools and the eight Layer 2s. However, actual earnings depend on trading activity and market conditions, and precise forecasts are uncertain.
