02

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 proposers, lane leaders, and archive nodes.

On-Chain by Default

Chats, channels, and HTML cards are written to Silica Protocol for permanent history.

End-to-End Encryption

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

Permanent History

Messages are part of an immutable ledger. Your data exists as long as the chain does.

Silica Powered

Silica Protocol

Silica Protocol is Obsidian's messaging layer for blobs. Rock delivers fast, encrypted messaging with feeless standard inclusion and an optional paid Priority lane.
