Uniswap Activates UNI Burning Mechanism on Eight Layer 2 Chains

The Uniswap community recently voted on an ambitious proposal that marks a significant step in the protocol’s evolution. The initiative aims to implement the fee switch across multiple versions of the protocol spread across eight Layer 2 blockchain networks, including Base, Arbitrum, and OP Mainnet. This mechanism, already active on Ethereum mainnet since December 2025, introduces an innovative model for rewarding investors.

Fee Switch Expansion: Base Leads Reward Generation

The recent vote reflects the exponential growth of activity on Uniswap across different chains. Since 2026, the Base blockchain has become the main fee generator for the protocol, surpassing Ethereum significantly with $55 million in accumulated fees. This impressive performance positions Base as the hub of Uniswap’s growth within the Layer 2 ecosystem.

The proposed expansion would leverage this momentum by activating the revenue capture system on eight networks, increasing the potential for reward distribution to token holders. With implementation, at least one-sixth of the fees charged to liquidity providers will be directed to a dedicated token pool.

Redemption Mechanism: How Investors Benefit from Burning UNI

The innovative model of the proposal involves burning UNI tokens as a mechanism to claim rewards. Investors will be able to burn amounts of UNI equivalent to the rewards accumulated in the fee pool, turning this act into a yield redemption. Experts project that this system could double or even triple current returns for holders.

On Ethereum mainnet, where the fee switch is already operational for v2 and some v3 pools, the mechanism has generated $3.3 million since its activation in December of the previous year. This performance history provides a solid foundation for multi-chain expansion.

Performance on Eth Mainnet and Growth Outlook

The gradual activation of the mechanism across different chains reflects Uniswap’s diversification strategy. While Ethereum remains an important pillar, growth on Layer 2 networks like Base demonstrates demand for distributed liquidity and lower fees. Expanding to eight chains should amplify this effect, creating multiple centers of value generation.

Recently, the UNI token experienced market volatility, dropping 13.22% over the past seven days, reflecting the overall dynamics of the crypto sector. The vote on the expansion proposal represents a critical moment to assess investor sentiment regarding the protocol’s structural improvements. With the voting concluded in March, it is expected that the results will clarify the future direction of the decentralized exchange platform.
