QSafe: Quantum-Secure Crypto Wallet
The world’s safest multichain wallet. Powered by Quranium.
Quranium 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).
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.
PK Modules (Probabilistic Key Modules): Adds entropy and randomness to private key protection, making extraction exponentially harder—even by quantum adversaries.
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, BSC (More chains coming in future like Polygon, Avalanche, and more) plus DApp access and ERC-20 management.
