From sign-in to vault lock in under 3 minutes. Here's every step of the journey.
Authenticate securely with your Google account. Apple Sign-In coming soon. No passwords are stored by CryptoVault — authentication is handled by Supabase OAuth.
Each Google account creates a completely isolated wallet. If you sign in with a different Gmail, you get a different wallet. Both can coexist on the same device.
Choose a strong password that encrypts your private key with AES-256-GCM encryption.
This password never leaves your device. It's used locally to encrypt and decrypt your private key. We cannot see it, reset it, or recover it. Think of it like a safe combination.
Write down your 12-word recovery phrase and store it in a secure, offline location.
Your seed phrase is the master key to your wallet. If you forget your password, this is the only way to recover. Anyone with your seed phrase has full control of your funds — keep it secret and safe.
Share your wallet address or QR code to receive MATIC on Polygon.
Your wallet address is the same on both testnet and mainnet (all EVM networks). For testing, get free MATIC from the Polygon Amoy faucet. For real use, send MATIC from any exchange or wallet.
Choose how much to lock and for how long — from 1 minute to 28 days.
Before confirming, you see the complete fee breakdown: your amount, the 5% platform fee, estimated gas fee, and the final locked amount. The transaction is signed locally in your browser.
The smart contract enforces the time-lock. No one — including CryptoVault — can override it.
Watch the live countdown in your dashboard. The progress bar shows exactly how much time remains. Once the timer hits zero, the Withdraw button activates.
After the lock expires, withdraw your crypto back to your wallet with one click.
The smart contract verifies the timestamp on-chain before releasing your funds. The full amount (minus the platform fee taken at lock time) returns to your wallet.
