Xmark and Nostr: Your Content, Amplified and Secured

Discover how Xmark enhances your Nostr experience by providing a public relay and bridging your X/Twitter content to this decentralized network.

Our Nostr Services

Public Nostr Relay

Xmark offers a free public Nostr relay. When you use this relay, your Nostr posts (notes) are automatically "marked" on the Bitmark blockchain. This creates a permanent, verifiable record of your content, proving you own it.

Relay address:
wss://nos.xmark.cc

This service is currently free. In the future, if blockchain storage costs increase significantly, a small fee might be introduced to keep it running smoothly.

Xmark Bridge: Tweets to Nostr

The Xmark browser extension doesn't just back up your X/Twitter posts; it also shares them on the Nostr network via our 'Xmark Bridge' account. This expands your reach and connects your ideas with the wider Nostr community.

Find and follow our bridge on Nostr clients using its public key:

You can also view its profile on a web client like Primal.net.

Why Bitmark for Nostr Content?

The Bitmark blockchain provides a strong, secure foundation for your Nostr activity when using our relay:

  • Permanent Proof: References to your Nostr posts are stored lastingly.
  • Decentralized & Secure: Your data's record is safe from single points of failure or censorship.
  • Enhanced Discoverability: Marked content can be easier to find and verify within the broader decentralized web, including services like Linkmark.

This ensures your important Nostr communications are not only shared but also have a verifiable trace of their existence and your ownership.
