Models

• ChatMessage is the main model that uses a JWMPayload as the dto
• HashchatStreamMessage is an internal dto that represents the fully signed and encrypted message stored in Stream
• SignedChatMessage is the payload of the encrypted message and contains information needed to verify the message
• JWMPayload is the final payload that contains message data

Services

• AuthService handles wallet connection, Lit authentication, and DID session management
• EncrypterService handles encryption and decryption. It is internally access by ChatService
• SignerService handles signing messages. It is internally access by ChatService
• ChatService handles sending and receiving messages from Stream

Example App

The example app under examples/ uses the AuthService and ChatService to authenticate, send a single message to a hardcoded channel, and receive a message from a hardcoded channel. Messages are signed and encrypted before sending, and they are decrypted and validated when receiving.
