QSafe wallet

Experience the future of crypto with QSafe — post-quantum signatures, multi-chain support, and full self-custody in one wallet.

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. Key Features Redesigned Glass Interface: A premium, easy-to-use experience with frosted surfaces, depth, and fluid motion. Quantum-Safe Security: Protect your assets with advanced PQC standards. Quantum-Safe MultiSig: Shared wallets with M-of-N approvals, secured by post-quantum SLH-DSA signatures. Multiple Accounts: Run many accounts from one seed, each with its own distinct post-quantum key. Multichain Asset Management: Unified interface for Quranium, Bitcoin, Ethereum, and EVM chains. Native Quranium Integration: Tap into the Quranium chain's full capabilities directly from your wallet. User-Friendly Interface: Designed for everyone, whether crypto-curious or experienced. Non-Custodial: You control your keys. Always. Advanced Key Protection: On-device encryption with memory-hard scrypt key derivation and per-account key separation.
