Uniswap, a decentralized protocol, plans to launch the third version of its platform, which aims to provide users with a seamless way to swap ERC-20 tokens without using an order book. In preparation for the launch of v3, the protocol conducted a "temperature test" to determine which blockchain to use. The proposal was to move Uniswap v3 to the Binance Smart Chain (BNB) instead of the Ethereum blockchain. The community was able to vote on this proposal through the UNI government forum using their UNI tokens.
