 ## Features
 
 - **Username Claiming**: Secure ownership with Ed25519 signatures
+- **Anonymous Users**: Auto-generated anonymous usernames for quick testing
 - **Service Publishing**: Publish services with multiple offers for connection pooling
 - **Service Discovery**: Direct lookup, random discovery, or paginated search
 - **Efficient Batch Polling**: Single endpoint for answers and ICE candidates (50% fewer requests)
 - **Semantic Version Matching**: Compatible version resolution (chat:1.0.0 matches any 1.x.x)
 - **TypeScript**: Full type safety and autocomplete
 - **Keypair Management**: Generate or reuse Ed25519 keypairs
+- **Automatic Signatures**: All authenticated requests signed automatically
