Your Security Is Our Architecture
Connect your own wallet and we never hold your keys — you should not have to trust anyone with your assets. Open an account instead and we hold them for you, deliberately and disclosed.
How It Works
Four layers of security protect your assets from generation to access.
Key Generation
Private keys are generated locally on your device using a cryptographically secure random number generator (CSPRNG). Keys are derived using BIP-32/BIP-44 hierarchical deterministic paths.
Encryption
All sensitive data (private keys, seed phrases) is encrypted with AES-256-GCM before storage. The encryption key is derived from your password using PBKDF2 with 100,000+ iterations.
Local Storage
Connect a wallet you control and its private keys stay on your device — they are never transmitted to any server. If you open an account with us, we hold the private keys to the deposit addresses we issue you, encrypted on our servers, so we can move funds on your instruction.
Biometric Access
Optional biometric authentication (Touch ID, Face ID, fingerprint) provides quick, secure access. The biometric data itself is handled by the OS and never exposed to the app.

How We Compare
This table describes MultiWallet's non-custodial mode, where you connect a wallet you control. An account with us is custodial by design and works like the middle column.
