Uniswap Sets Vote to Expand Fee Switch Across Eight L2s as UNI Tops $4

Automated v3 fees on additional chains would channel more proceeds to UNI burns, lifting protocol revenue.

Overview

  • Uniswap governance scheduled an onchain vote for Feb. 27–Mar. 1, split into two transactions, to widen fee sharing beyond Ethereum.
  • The proposal would replace pool-by-pool activation with a tier-based v3 model and a v3OpenFeeAdapter that applies fees by default to all new v3 pools.
  • Fees on Base, OP Mainnet, Arbitrum, Celo, Soneium, Worldchain, X Layer, and Zora would flow into per-chain TokenJars and then bridge to Ethereum for UNI buybacks and burns.
  • Analysts estimate roughly $27 million in additional annualized revenue on top of about $34 million already implied by recent burns, with Q1 2026 gross profit near $3.12 million.
  • UNI rallied roughly 12–20% to intraday highs above $4 with rising volume and open interest, as traders also cited a broader BTC/ETH rebound and a reported BlackRock UNI purchase.
