Uniswap

This proposal, submitted by GFX Labs/Oku Trade, suggests deploying Uniswap V4, a new version of the decentralized exchange protocol, on four different blockchain networks: Sei, Etherlink, Pharos, and 0G. The goal is to expand Uniswap's reach, generate more fees for the protocol, and provide new environments for developers to build on. GFX Labs will cover all costs associated with these deployments, meaning no funds will be taken from the Uniswap treasury.

This proposal aims to update Uniswap's cross-chain governance system to improve security and efficiency. It involves two main changes: first, transferring ownership of Uniswap v2 and v4 contracts on Soneium and X Layer to CrossChainAccount contracts, which are considered best practice for executing messages from the Ethereum Mainnet on the OP Stack. Second, it will migrate the messaging system for Uniswap deployments on Avalanche and MegaETH from the older LayerZero v1 to Wormhole, a different cross-chain communication protocol, due to LayerZero v1's deprecation.

This proposal aims to expand the Uniswap protocol fee collection and burning mechanism to Robinhood Chain. It will enable fees for Uniswap v2 and v3 on Robinhood Chain, with v4 fees to be addressed in a separate future proposal. The collected fees will accumulate in a 'TokenJar' on Robinhood Chain and then be used to burn UNI tokens by bridging them back to the Ethereum mainnet.

This proposal is the first part of a two-part plan to activate protocol fees on Uniswap v4 pools across several blockchain networks. It builds on previous proposals that enabled fees on Uniswap v2 and v3. The proposal introduces a new 'V4 Fee Controller' system, consisting of a V4FeePolicy and V4FeeAdapter, to manage the collection of fees from v4 pools, which have a more complex and dynamic fee structure due to their 'hook' architecture. This specific vote will activate fees on v4 pools on Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism, and Robinhood Chain.
