Security, designed
from the ground up.

SafeVault isn't a wallet. It's an offline protection layer for your seed phrase, built on an architecture that keeps you completely off the grid.

COMMON EXPOSURE RISKS

Where seed phrases are often exposed

Most cryptocurrency losses occur due to insecure seed phrase storage. SafeVault is designed to reduce these risks.

Screenshots Images automatically synced to the cloud
Cloud storage Files synced across devices
Email or messaging Accidental sharing of seed phrases
Compromised devices Seed phrases exposed in connected or insecure environments
SECURITY ARCHITECTURE

The SafeVault Security Architecture

Each security layer was designed to reduce the most common seed phrase exposure risks and turn good security practices into a consistent offline protection model.

Offline-first

Sensitive operations run locally on your iPhone. Your seed phrase never touches the internet.

Strong encryption

Seeds are protected with authenticated AES-256-GCM encryption and robust key derivation.

Secure storage

Sensitive data is stored only in the iOS Secure Keychain.

No cloud exposure

SafeVault does not depend on servers, accounts or cloud infrastructure.

OFFLINE ARCHITECTURE

Your seed never touches the internet

SafeVault follows a strictly offline model. Encryption and recovery happen entirely on the device.

The physical vault is created using an encrypted QR code or a SafeVault Card NFC.

ARCHITECTURE
Network calls Disabled during sensitive operations
Data transport Encrypted QRCode / NFC
Cloud storage None
Account required No
CRYPTOGRAPHY

Bank-grade encryption

Each seed is encrypted before the physical vault is created.

Each operation uses unique random salt and nonce values.

Encryption AES-256-GCM
Key derivation PBKDF2-SHA256
Iterations 1.2M rounds
Salt 32 random bytes
ACCESS CONTROL

Biometric authentication

Face ID or Touch ID protects access to the encrypted vault.

Master password

A master password is used to derive the cryptographic key.

Secure memory

Sensitive buffers are cleared from memory after use.

RUNTIME SECURITY

Protection against tampering

SafeVault performs integrity checks every time the app starts.

Suspicious environments trigger automatic security locks.

PROTECTIONS

Jailbreak detection

Prevents execution on compromised devices.

Screen capture protection

Sensitive content is hidden if screen recording is detected.

Debugger detection

Blocks reverse-engineering tools.

CONTROLLED RECOVERY

Seed exposure is limited

During recovery, words appear in small groups.

This reduces the risk of accidental exposure.

SECURITY PRINCIPLES

The seed is never stored in plain text

Seeds exist decrypted only temporarily in memory.

Zero trust in the network

Sensitive data is never transmitted over the internet.

Secure memory wiping

Sensitive buffers are cleared after cryptographic operations.

COMPATIBILITY

Compatible with BIP-39 wallets

SafeVault is not a wallet. It works alongside wallets that use BIP-39 seed phrases, adding a dedicated offline protection layer.
