Solo dev building @vaultkeepr_xyz
Password manager where even I can't see your data
Decentralized · zero-knowledge · open source · crypto · privacy

[0xjust1 · 🇫🇷 @0xJust1]

Remember my post about what happens to your passwords when you die ?

The smart contract on @base was live, but the UI was missing.

Today, it's officially ready. Here is the first live demo on iOS:

How it works technically :

• On-device encryption: Your vault is encrypted directly on your device, then pushed to IPFS for seamless multi-device sync.
• Smart contract heartbeat : The contract monitors regular check-ins. If you stop, it handles the legacy release.
• 100% customizable: You define the delays, triggers, and who gets access.

I'm opening some slots for the Android version today.

DM me if you are interested!

@YannDarwin Deepseek est vraiment le meilleur model avec un rapport qualité/prix imbattable. Derrière il y’a le model de Xiaomi (Mimo v2.5) qui est également très bon.

Spent the last year building this. Full story in the thread with the architecture, the failures, the Account Abstraction approach. Sharing because I wish I had seen more honest builds when I started.

I spent the last year building a password manager with no servers. No email login. No way for me to see your data.

Here is why I stopped using Bitwarden and built my own.

Just published the full story of why I built VaultKeepR - a password manager with no servers

If you are curious about building in public or privacy tech, this thread covers everything from CRDT sync nightmares to Account Abstraction

What frustrates you about your current password manager ?

@base I built this because I wanted a password manager that could survive its own company shutting down.

No server = nothing to breach.

@ Claude can you help him do that ? 😏

Sharing the main UI demo here for anyone interested in the layout.

Thanks for any feedback :)

In crypto we always say, not your keys, not your coins. It's time we start treating our personal data the exact same way.

That is why I spent the last few months building VaultKeepR. It encrypts all your passwords locally on your phone and backs them up privately on a decentralized network, so no single company holds the keys to your life.

I recorded a quick clip to show what the app looks like. It does not show everything, but it gives a good feel of the overall UI.

I would love to hear what you think.

Finally integrated the decentralized "Dead Man's Switch" into the mobile app. Here is the video demo in action on iOS.
