Support for Cosmos SDK Stargate in CosmJS has been ongoing work for several months now. Stargate is released and CosmJS is here to connect to it.

Let's explore what is new for Stargate support:

@cosmjs/proto-signing, which implements the new SIGN_MODE_DIRECT based on protobuf serializations
@cosmjs/stargate, which provides a high level client for querying, signing and broadcasting
@cosmjs/cosmwasm-stargate for interacting with CosmWasm smart contracts on Stargate chains

What this will cover

Never forget to activate that virtualenv or set that environment variable ever again...
