Frequently Asked Questions
Everything you need to know about VaultKeepR's architecture and security.
What is VaultKeepR and how does it work?
VaultKeepR is a decentralized, zero-knowledge password manager. It encrypts all your credentials directly on your device using XChaCha20-Poly1305, then stores the encrypted vault on the IPFS peer-to-peer network. Nobody else can read your data.
Do I need an email address or a crypto wallet to sign up?
No. Powered by Account Abstraction (ERC-4337), the app automatically provisions a Smart Account in the background when you register your biometric passkey. You do not need to provide an email or connect any external web3 wallet like MetaMask.
How are blockchain transaction fees (gas) paid?
All blockchain network fees required to record or claim your vault are sponsored by our Paymaster service (Pimlico). The use of the Base L2 blockchain is transparent and completely free of charge for users.
What happens if I lose my device?
VaultKeepR features Shamir Secret Sharing recovery. Your recovery key is split into 5 encrypted fragments distributed across devices, trusted contacts, and on-chain smart contracts. Reconstructing any 3-of-5 fragments restores full access.
Is VaultKeepR open source?
Yes. Our cryptographic core and sync libraries are published in full under the MIT license. The code is publicly auditable for absolute transparency.
