How can I bridge my Nostr account to Bluesky so they see my posts?

We'll have a separate guide on that, coming soon!

Notes

Please keep in mind that both the Mostr Bridge and Bridgy Fed are new services, still undergoing improvement, and may not be reliable. In addition, Nostr and AtProto are also both young protocols - this is a recipe for bugs!

It can take 15 minutes+ for posts and follows to federate through both bridges. Maybe even longer. Please be patient!
