nostr-qrchat

ephemeral, anonymous chat via QR codes over nostr

Use cases:

put a QR code on your letter box so people at your door can still contact you when you are not at home without any PII
put QR codes anywhere where people may want to open instant support chat sessions
put QR code at your website to let people chat with you
...

Every QR code is linked to a specific token. This has following advantages:

You know which QR code was used which tells you the location of people (assuming they didn't save the token but this can be solved using TOTPs)
You can invalidate existing QR codes to prevent spam
You can configure prompts per QR code

Setup

Clone repository: git clone git@[git.ekzyis.com:55680]:ekzyis/nostr-qrchat
Build binary: go build
Enter your bech32 nostr pubkey (npub) as NOSTR_PUBKEY in .env
Generate random token: openssl rand -hex 8 >> tokens
Run ./nostr-qrchat
