Founded in 2017 by Martin Koppelman, Gnosis Protocol is presently in version 2 called Gnosis Protocol v2 (GPv2). It is a fully permissionless DEX trading protocol for Ethereum, which leverages batch auctions to provide MEV protection. The batch auction mechanism ensures tight slippage, without relying on relative ordering of the transactions.  Gnosis Protocol v2 integrates with liquidity sources across various DEXs to offer the best prices to traders.
