V1
FEATURES

v1 Preview Clients

Web messenger and prototype mobile shells focused on core messaging.

Zero Gas

Standard messages cost no gas. Priority inclusion is optional and paid in OBS, with fees distributed to committee validators, proposers, lane leaders, and archive nodes.

On-Chain by Default

Chats, channels, and HTML cards are written to Silica Protocol with finalized ordering and archive-backed history.

End-to-End Encryption

Privacy comes from client-side encryption. Only intended recipients can read content.

Archive-Backed History

Messages are part of an immutable ledger, with archive nodes preserving long-term retrieval.

Silica Powered

Silica Protocol
