Sommelier consists of the Cosmos Stargate SDK, its Tendermint-based consensus layer and a decentralized, bidirectional Ethereum bridge, managed by a global network of validators. Liquidity Providers (LPs) will be able to use the Sommelier to execute complex, and automated financial transactions, such as portfolio rebalancing, limit orders, batched orders, as well as a host of other features that traders have come to expect from CeFi, but that is not currently available in DeFi. Sommelier has not launched the token yet.
Both the directional ethereum bridge and automated signature management for ethereum transactions are still a work in progress. Currently, Sommelier has a basic impermanent loss calculator for LP’s and still in the early days of development.
