Volume successfully launched Sommelier’s first iteration as PeggyJV, bringing the Cosmos Ethereum bridge to market and resulted in Sommelier raising a total $25MM in funding to launch the first automated DeFi blockchain to manage Liquidity Provider capital on Ethereum via the Cosmos. Sommelier consists of the Cosmos Stargate SDK, its Tendermint-based consensus layer and a decentralized, bi-directional Ethereum bridge, managed by a global network of validators.
