Fact Check
The statement is overwhelmingly supported by the provided primary sources. Multiple high-authority news outlets and market data providers corroborate the core claims.1. **Price Increase and Percentage:** There is a strong consensus that the UNI token's price increased by exactly 19%. This specific figure is explicitly mentioned in sources from major platforms like Coinbase, CoinDesk, Yahoo Finance, Tokenpost, and Ainvest. The consistency of this number across various credible publications lends it high credibility.2. **Timing and Causation:** The sources consistently link this 19% price surge directly to the commencement of a specific governance vote. The phrasing used, such as "at the time of", "as governance vote... opens", and "after voting opens", establishes a clear temporal and causal connection between the two events.3. **Subject of the Vote (Protocol Fees):** All relevant sources confirm that the governance vote was centered on activating protocol fees, often referred to as the "fee switch". This is the central theme of the news coverage.4. **Subject of the Vote (Token Burn):** While not mentioned by every top-tier source, the "token burn" aspect is explicitly included in the reports from Tokenpost and discussed in detail by another source from Ainvest, which is titled "Uniswap's Fee Switch and UNI Burn Mechanism". This confirms that a token burn was a key component of the proposal being voted on, even if some headlines focused solely on the broader "fee switch" concept. The absence of this detail in some reports is a matter of journalistic focus rather than a contradiction.In summary, all components of the statement are well-supported by the evidence. The core facts—the 19% price increase and its link to the governance vote on protocol fees—are confirmed by multiple, highly authoritative sources. The inclusion of the "token burn" is also substantiated, making the entire statement a factual and accurate summary of the event.
Summary

Uniswap announced via X that all application and API interface fees have been reduced to zero. A governance vote approved activating fee switches for v2 and v3 on the Unichain mainnet, set to occur after a two-day lock period. Upon activation, protocol fees will trigger the UNI token burn mechanism for v2 and v3. The December 25 vote passed with 99.9% community approval and authorized redirecting protocol fees from liquidity providers to onchain burns and fee discount auctions.
