Blocks threats from quantum computing with advanced Post-Quantum Cryptography (PQC) standards, ensuring your digital assets are protected against both classical and quantum attacks. Manage your multichain wallet in a single secure interface, supporting Quranium, Bitcoin, Ethereum, and EVM chains, making it ideal for users who hold assets across multiple blockchains.

Overview

QSafe: Quantum-Secure Crypto Wallet
The world's safest multichain wallet. Powered by Quranium.

QSafe is the world's first multi-chain wallet built for the quantum age; a secure Chrome extension powered by native Quranium chain integration and fortified with Post-Quantum Cryptography (PQC). Now with a beautiful redesigned interface, quantum-safe MultiSig, and multiple accounts from a single seed.

New in 4.8: A Beautiful New Glass Experience
QSafe has been fully redesigned with a premium glassmorphism interface:
Frosted Glass Surfaces: Translucent, depth-layered cards float over an ambient Quranium brand glow.
Embossed Detail: Raised-glass cards with soft inner highlights and gentle depth shadows.
Fluid Motion: Surfaces ease into place and respond to your touch, never getting in your way.
Focused Menus: Opening a menu frosts the wallet behind it, so you always know exactly where you are.
Clean, calm, and unmistakably Quranium — designed to feel effortless whether you are new to crypto or a power user.

Quantum-Safe MultiSig
Protect shared funds with multi-signature wallets that are post-quantum from the ground up:
Shared Control: Create wallets with multiple owners and require a set number of approvals (M-of-N) before any transaction can execute—no single point of failure.
Post-Quantum Approvals: Every approval is an independent SLH-DSA signature recorded on-chain, purpose-built to handle quantum-safe signatures.
On-Chain Owner Management: Add or remove owners and change approval thresholds directly from your wallet.
Full Oversight: Review, approve, or revoke pending transactions before they execute.
Ideal for teams, treasuries, DAOs, and families who want quantum-grade protection with no single point of failure.

Multiple Accounts, One Seed
Create as many accounts as you need from a single recovery phrase. Each account derives a distinct, hardened post-quantum (SLH-DSA) key, so one compromised account never exposes the others. New wallets use a 24-word phrase for maximum quantum-grade security.

Built for the Quantum Age
In a world where quantum computing threatens traditional encryption, Quranium leads the way with the strongest cryptographic defenses available:
SLH-DSA (SPHINCS+): A NIST-approved, hash-based digital signature algorithm, offering protection against both classical and quantum attacks.
ML-KEM: A lattice-based key encapsulation mechanism used for encrypting and exchanging keys securely.
Encrypted Key Storage: Your recovery phrase is sealed on-device with a memory-hard scrypt key-derivation function and XSalsa20-Poly1305 authenticated encryption, with per-account key separation so one compromised key never exposes the others.

Seamless Multichain Experience
Manage your digital assets across multiple blockchains in one secure interface:
Native Quranium Chain: Fast, secure, and quantum-safe by design.
Bitcoin (BTC): Secure storage and transaction support, with future quantum-safe capabilities planned.
Ethereum (ETH) & EVM Chains: Full support for ETH and BSC (more chains coming, like Polygon, Avalanche, and more) plus DApp access and ERC-20 management.
