Sommelier

The initial release of the Sommelier blockchain will consist of a standard cosmos-sdk chain and the recently completed Gravity Bridge refactor.

Gravity Bridge

The Gravity Bridge requires some additional pieces to be deployed to support it:

• Ethereum Contract and associated tooling
• Orchestrator/Relayer binaries built from the go.mod commit
