To make your repository discoverable by other Nostr clients, you need to publish NIP-34 events: + +1. Go to your repository page on gittr.space +2. Click **"Push to Nostr"** +3. Confirm the prompt in your NIP-07 wallet + +This publishes: +- **Announcement event** (kind 30617) - Announces your repository +- **State event** (kind 30618) - Contains current repository state (branches, commits, etc.) + +**Important**: +- `git push` updates the repository on the bridge server +- "Push to Nostr" publishes NIP-34 events to Nostr relays +- Both are needed for full functionality: bridge for git operations, Nostr events for discovery +- Publishing to Nostr always requires signer approval (NIP-07 extension or local nsec signer) + +## Push Paywall Flow (Optional Per Repository) + +Some repositories require sats payment before push is accepted. + +Flow: +1. Repo owner sets **Push Cost (sats)**. +2. User opens repo in web UI and clicks **Push to Nostr** to create invoice. +3. User pays the invoice (QR/BOLT11). +4. Server grants short-lived, **single-use** push authorization. +5. User retries `git push` to continue the Git operation. **Each successful push consumes one authorization.** + +Notes: +- Repo owners can enable non-zero Push Cost after configuring either LNbits Invoice Key or Blink API Key in Settings -> Account. +- For SSH, authorization is bound to payer pubkey + owner/repo, so concurrent users are authorized independently. + +## Troubleshooting + +### SSH asks for a password (after you added your key) + +gittr does **not** use a shell password for Git over SSH. A password prompt almost always means **public key authentication did not run successfully** (SSH then falls back to password). + +1. **Confirm you use the right private key** (same machine where you generated or pasted the **public** key into Settings → SSH Keys): + ```bash + GIT_SSH_COMMAND='ssh -v -o IdentitiesOnly=yes -i ~/.ssh/' git ls-remote git@git.gittr.space:/.git + ``` + In the `-v` output you should see **Offering public key** and then **Server accepts key** (or similar). If it skips your key, fix the `-i` path or add the key to `ssh-agent`. + +2. **Try the `git-nostr@` username** if `git@` still misbehaves on your network or client; both are valid on gittr. + +3. **Wait a few seconds** after saving the key in the web UI so relays and the bridge can refresh `authorized_keys`. + +4. **Server operators:** if `sshd` was configured with `Match User git` and a **separate** `AuthorizedKeysFile /etc/ssh/git-authorized_keys`, that file is a **manual copy** of keys and goes **stale** whenever someone adds a key in the UI — `git@` logins then fail until sshd reads the **live** file the bridge updates (`/home/git-nostr/.ssh/authorized_keys`).
