NIP-21

nostr: URI scheme

draft optional

This NIP standardizes the usage of a common URI scheme for maximum interoperability and openness in the network.

The scheme is nostr:.

The identifiers that come after are expected to be the same as those defined in NIP-19 (except nsec).

Examples
  • nostr:npub1sn0wdenkukak0d9dfczzeacvhkrgz92ak56egt7vdgzn8pv2wfqqhrjdv9
  • nostr:nprofile1qqsrhuxx8l9ex335q7he0f09aej04zpazpl0ne2cgukyawd24mayt8gpp4mhxue69uhhytnc9e3k7mgpz4mhxue69uhkg6nzv9ejuumpv34kytnrdaksjlyr9p
  • nostr:note1fntxtkcy9pjwucqwa9mddn7v03wwwsu9j330jj350nvhpky2tuaspk6nqc

Linking HTML pages to Nostr entities

<link> tags with rel="alternate" can be used to associate webpages to Nostr events, in cases where the same content is served via the two mediums (for example, a web server that exposes Markdown articles both as HTML pages and as `kind:30023’ events served under itself as a relay or through some other relay). For example:

<head>
  <link rel="alternate" href="nostr:naddr1qqyrzwrxvc6ngvfkqyghwumn8ghj7enfv96x5ctx9e3k7mgzyqalp33lewf5vdq847t6te0wvnags0gs0mu72kz8938tn24wlfze6qcyqqq823cph95ag" />
</head>

Likewise, <link> tags with rel="me" or rel="author" can be used to assign authorship of webpages to Nostr profiles. For example:

<head>
  <link rel="me" href="nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqyd8wumn8ghj7un9d3shjtnhv4ehgetjde38gcewvdhk6qpq80cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwswpnfsn" />
</head>
