Both frontend and backend of DegenRocket are now open source, so you can run your own instance, allowing your users to sign messages with an Ethereum private key.

Further steps towards censorship-resistant decentralized Signer and Protocol Agnostic Social Media (SPASM) should be:
- support for alternative private keys (Nostr, GPG, Hive, etc.),
- support for alternative protocols (Nostr),
- interoperability between instances,
- token-gated communities,
- move to a decentralized code sharing platform.
