Frequently Asked Questions
How safe is my data in the vault?
Your vault data is encrypted client-side with AES-GCM using keys derived from your password and wallet. It’s extremely secure — even we can't access it.
How is it safe to store privacy data on a blockchain?
Data is encrypted before touching the blockchain. Even if someone finds your data, it’s unreadable without your password and wallet signature.
Do you store my data or password?
No. CroVault never stores your data or password. Everything is encrypted in your browser and saved directly in your blockchain vault.
Why do I need to sign a message?
Signing a message with your wallet creates a unique key for your session. It enhances security without storing anything sensitive.
What if I forget my password?
If you forget your password, we cannot recover your vault. This is by design: zero-access encryption.
Can I access my vault from another device?
Yes — your CroVault vault is decentralized. With your wallet and password, you can access your data from any device, anywhere.
Can I edit or delete data later?
Yes. You can edit or delete saved credentials, notes, or wallet addresses.
How can I store my Authenticator accounts?
You can store Authenticator secrets like TOTP keys as notes. Save the Base32 key, algorithm, and interval manually during setup.
Is the vault open-source?
Yes. The code is open for review. CroVault is a static dApp, fully transparent and verifiable.
What blockchain is used?
CroVault uses the Cronos blockchain — an EVM-compatible, fast, low-cost layer-1 chain.
What is the difference between a vault and a wallet?
Your wallet holds crypto. Your vault securely stores passwords, notes, and secrets using blockchain smart contracts.
How do I create a vault?
Connect your wallet and set a password. Then click “Create Vault” and confirm the transaction. A small fee is required.
How much does it cost to save data?
You pay a Cronos network fee and a small CroVault fee when saving. Reading and deleting data is always free.
When I try to connect my wallet, nothing happens?
Try using your wallet’s in-app browser, switching browsers, clearing cache, or disabling extensions that interfere with wallet connections.
Why is signing or saving sometimes slow?
Delays are usually caused by network congestion or wallet popup timing. Just wait a few seconds.
