Every feature built from the ground up with self-custodial principles. Your crypto, your keys, your control.
Your private key is generated in your browser and never leaves your device. We have zero access to your funds, keys, or password. You are the sole custodian.
Your private key is encrypted at rest using AES-256-GCM via the Web Crypto API with PBKDF2 key derivation (600,000 iterations). Even if someone accesses your device, they need your password to decrypt.
Lock your crypto for 1 minute to 28 days using immutable on-chain smart contracts. Once locked, nobody — including CryptoVault — can access your funds before the unlock time.
Test everything for free on Polygon Amoy testnet with zero real money. When you're confident, switch to Polygon Mainnet with one click in the dashboard.
Works seamlessly on Chrome, Safari, Firefox, Edge across Mac, Windows, iPhone, and Android. Fully responsive design optimized for every screen size.
A small 5% platform fee is displayed before every vault lock transaction. No hidden charges, no subscription, no withdrawal fees. Gas fees are set by the network.
Every transaction — locks, unlocks, sends, receives — is permanently recorded on the blockchain. Verify any operation on the public block explorer at any time.
Back up your 12-word seed phrase during wallet creation. If you forget your password or switch devices, restore your wallet instantly using your seed phrase.
