Frequently Asked Questions
Common questions about Nostrame
If you forget your password, you can recover accounts derived from your seed phrase. However, imported accounts (keys added separately) cannot be recovered from the seed phrase - they require your vault password or a vault backup with its backup password. Protect both your vault password and backup to avoid losing imported accounts.
Nostrame works with all Chromium-based browsers including Google Chrome, Brave, Microsoft Edge, Opera, and Vivaldi. Firefox support is planned for a future release.
Yes! Nostrame implements the NIP-07 standard, making it compatible with any Nostr web client that supports browser signing. This includes popular clients like Snort, Coracle, Nostrudel, Iris, and many others.
Nostrame focuses on security and multi-account management. It supports hierarchical deterministic key derivation (NIP-06), meaning you can derive unlimited accounts from a single seed phrase, plus import existing keys separately. It also offers granular permission controls per website and per event kind.
No. Nostrame operates entirely locally on your device. There is no telemetry, no analytics, and no external server communication. The only network requests are to Nostr relays when fetching profile metadata, and this is done directly from your browser.
