According to Foresight News: Uniswap community has initiated a temperature check vote for deploying V2 on all chains compatible with Uniswap V3. The voting is set to conclude on August 31 at 03:30. If the vote passes, Uniswap will launch an on-chain vote on September 1. If the on-chain vote is approved, the on-chain vote will be executed on September 12.
The proposal states that there is a demand for Uniswap V2 AMM on non-Ethereum chains, and many V2 forks have already been deployed with varying degrees of modifications, which may be unsafe for users. A standardized version of Uniswap contracts can provide security for new on-chain DEX users, including traders, liquidity providers, and developers.
