Mr.Crown // Renarchy on Nostr: Because Substr is community-first, we don’t pull in every post like most clients ...
Because Substr is community-first, we don’t pull in every post like most clients do. We only show posts that are actually shared inside a substr.
To support this, I’ve introduced a new “event ID” post type. Under the hood, it’s published as a standard kind :6 repost, so it stays compatible with other clients while fitting naturally into Substr’s structure.
It’s already working, but I’m still fine-tuning the experience. Npubs will be displayed as usernames and link directly to /u/. Links will no longer show as raw URLs, but as compact previews, and video links can be played directly in a modal player.
Next step: you’ll be able to paste not just an event ID, but also a post URL from another client, and Substr will resolve and render it automatically.
