UNI Uniswap management to vote on initiation of protocol fees involving multi-chain and token destruction mechanisms
Uniswap management is preparing to vote on a proposal that will enable protocol fees for the first time in some Uniswap v4 liquidity pools. At the same time, another proposal plans to extend the fee mechanism already implemented in Uniswap v2 and v3 to Robinhood Chain.
Both proposals have reached the final on-chain voting stage. Voting will open on Sunday and continue until July 26. Hayden Adams, founder of Uniswap, said the proposals are expected to have a significant impact on the UNI destruction mechanism, highlighting the current trading volume on Robinhood Chain.
Uniswap v4 proposal: Enabling agreement fees in specific pool types
The Uniswap v4 proposal requires enabling agreement fees in fixed fee pools, pools created through perpetual swap auctions, and pools that use aggregator hooks. The regulation will cover Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism and Robinhood Chain networks.
According to the proposal text, voting on the remaining five networks will be held separately later. This is because Uniswap's GovernorBravo governance protocol allows up to 10 transactions on the chain to be executed on a single proposal.
Robinhood Chain Proposal: Extend fee mechanisms to v2 and v3 pools
Another Robinhood Chain proposal, initiated by Hayden Adams, aims to enable fees for Uniswap v2 and v3 pools on the network. All three versions of the Uniswap protocol were launched on July 1 with the launch of Robinhood Chain's main network.
According to data included in the proposal, as of July 10, the total transaction volume of Uniswap apps on Robinhood Chain had exceeded $6 billion. The Ethereum Layer 2 network, developed on the basis of Arbitrum infrastructure, recorded approximately US$3.1 billion in decentralized exchange transactions in its first week. It is worth noting that Meme coins dominate the initial transaction.
Agreement fees will be transferred to the UNI Destruction Mechanism
Agreement fees charged for the two proposals will be transferred to the UNI Destruction Mechanism. The mechanism was established by the UNItification governance regulation passed in December 2023 with a support rate of 99.9%.
With this governance change, agreement fees have been enabled for the pools of Uniswap v2 and v3 on the Ethereum main network, and 100 million UNIs have been destroyed in the Uniswap vault. However, the implementation of v4 fees was deferred until subsequent proposals pending the completion of the necessary technical infrastructure.
It is reported that the fee mechanism has now been extended to 11 different networks. Under the Uniswap v4 proposal, the agreement last month set a record for the destruction of 186,000 UNIs in a single day.
v4 fee mechanism is more complex, and adopting classification management
Enabling fees in Uniswap v4 requires a more complex infrastructure than previous versions. V2 and v3 use a fixed rate hierarchy, while v4's hook architecture allows the pool to change fees block by block.
The new proposal creates a management-controlled system that classifies pools into specific "families" and calculates fees for each pool based on preset rules, rather than setting separate rates.
Both proposals adopt the accelerated governance process adopted under Unification. This process omits the opinion collection stage and directly enters on-chain voting after the five-day Snapshot voting period.
