Symudol
Carry your identity on your phone, under your control.
Symudol keeps your Nostr identity on your mobile, so the apps you use never hold it. When an app wants to post as you, it asks Symudol, and you decide. Symudol runs on Android.
Keys stay on your phone
No copying private keys into random mobile apps. The signer keeps sensitive material isolated on your device.
- Device-local vaultPrivate keys are stored securely on the phone
- Multi-identity supportMultiple Nostr accounts managed cleanly
- Focused signerA dedicated signer, not a bloated everything-app
Explicit approval flows
You see who is asking and what they want before you approve or reject. Symudol only skips the question when you have already remembered a decision for that app and that kind of request.
- Clear request UISigning requests presented with full context
- Approve or rejectYou decide, unless you have remembered a decision for that request
- Remembered permissionsRemember a decision for one app and one kind of request, and revoke it in Trusted Nostr apps

- get_public_keyShare your public key with requesting apps
- sign_eventSign Nostr events without exposing the private key
