Uniswap is pushing its protocol fee system to three more blockchains. A governance proposal posted on May 16 seeks to activate fee collection and UNI token burning on BNB Chain, Polygon, and Celo, bringing the total number of chains with live protocol fees to 13.
The move is part of a phased rollout that started on Ethereum mainnet in late December 2025. Since then, fees have already gone live on nine additional chains including Arbitrum, Base, OP Mainnet, Soneium, X Layer, Worldchain, and Zora. The latest expansion targets three of the most active alternative networks in DeFi.
How the fee structure works
Fees are routed into what Uniswap calls TokenJars on each respective chain. From there, the collected UNI tokens get bridged back to Ethereum mainnet and sent to the 0xdead address, a well-known burn address that permanently removes tokens from circulation.
The Celo activation is actually a fix. A prior governance proposal, numbered #94, contained a configuration error that prevented fees from going live on the network. This new proposal corrects that mistake while simultaneously onboarding BNB Chain and Polygon with fresh TokenJar infrastructure.
