Overview
- The governance vote that approved Proposal 100 executed on July 27, 2026, with about 46.6 million UNI in favor and 1.27 million against, triggering protocol fees on v4 pools across seven networks.
- Uniswap’s founder Hayden Adams says the v4 design adds a separate protocol charge that traders pay and does not reduce the existing pool fees that liquidity providers earn.
- Early on‑chain measures show roughly $325,000 per day flowing into the protocol, and collected assets are sent to TokenJar contracts where claimants must burn UNI through the Firepit to redeem value.
- A coalition of liquidity providers and rival DEX founders warn the change could weaken LP economics and prompt liquidity to move to competitors, a risk that Uniswap’s leadership disputes and says will be judged by LP behaviour and volumes.
- The protocol can alter rates or apply overrides if needed and observers will watch pool liquidity retention and cross‑chain trading volumes as the key tests of whether the fee switch sustains revenue without driving capital away.
