Sommelier is a co-processor for Ethereum that automates Liquidity Providers' (LPs) portfolios to maximize their yields. LPs will be able to use Sommelier to author and execute complex, automated financial transactions, such as portfolio rebalancing, limit orders, batched orders, and other features that traders have come to expect from CeFi. Sommelier is composed of the Cosmos Stargate SDK, its Tendermint-based consensus layer, and a decentralized, bi-directional Ethereum bridge managed by a global network of validators.
