After reading through other deployment proposals I’d like to submit xDai Chain for consideration. The xDai stable-payments chain provides a unique scaling opportunity and an attractive option for Uniswap v3 deployment. A stable trading environment with low, predictable fees creates new scenarios and use cases for trading not available on other networks.
xDai is upgraded to the latest EVM patchset (Berlin HF now active) and supported by 2 clients - Open Ethereum and Nethermind. The current validator set features projects actively engaged within the Ethereum ecosystem. The energy-efficient delegated Proof of Stake consensus is currently secured by 16 validator pools and 270 active delegators (as of 5/26/2021) with additional validator candidates planning to onboard in the near term. xDai has been in production since 2018 and received support from the Ethereum community as a neutral and secure scaling solution.
xDai depends on multi-chain interoperability provided by several fully audited bridges featuring fast withdrawals (typically confirmed within minutes). A distributed governance board oversees changes related to bridge functionality and security.
The xDai chain recently increased block capacity by more than 30% and is supporting a large range of projects including high volume applications like Perpetual Protocol and dark forest. The chain is available to assist with scaling and ready to support Uniswap v3. As other proposals have mentioned, there is much to gain in providing swaps on additional EVM compatible networks. xDai should be considered in this conversation as a viable and available deployment option for Uniswap v3.
