Uniswap has carried out a major token burn following approval of the long-anticipated fee burn proposal, removing 100 million UNI from the protocol’s treasury, equivalent to approximately $596 million at current prices.
Analyst EmberCN said on-chain data shows the burn transaction was completed around 4:30 a.m. UTC on December 28, confirming the first large-scale implementation of the governance decision passed earlier this week. This transaction permanently reduced the token supply of Uniswap (UNI), making it one of the largest burns ever undertaken by a decentralized finance protocol.
The highly anticipated Uniswap protocol fee switch, dubbed “UNIfication,” passed with 99.9% support on Thursday. More than 125 million UNI tokens voted in favor of the proposal, while only 742 tokens voted against it, highlighting the broad consensus among token holders.
Several crypto executives with significant voting power supported the unification plan, including Jesse Waldren, founder and managing partner of cryptocurrency-focused venture capital firm Valiant. Kain Warwick, founder of decentralized finance protocols Infinex and Synthetix. and Ian Lapham, who previously worked as an engineer at Uniswap Labs.
