Introducing QSafe: The First Quantum-Secure, Multi-Chain Crypto Wallet, built for the Post-Quantum Era

7 Min Read

Dubai & Switzerland – 11 June, 2025 – Quranium, the pioneer behind the first quantum-secure blockchain infrastructure, has today launched QSafe Quantum Secure Crypto Wallet (‘QSafe Wallet’), a next-generation crypto wallet designed from the ground up to protect digital assets in the quantum era. 

Built with SLHDSA and ML-KEM, two of the leading post-quantum cryptographic algorithms selected by National Institute of Standards and Technology (NIST), QSafe offers quantum-resilient signatures and encrypted backups by default. It supports Bitcoin, Solana, EVM chains, and Quranium’s native Layer 1, delivering a seamless, secure, and cross-chain experience for both newcomers and advanced users.

“In 2024, over $2.2 billion was lost to cryptocurrency hacks and scams, with approximately $964 million to $1.86 billion attributed to wallet vulnerabilities such as private key compromises and access control failures, primarily driven by phishing, misconfigured multisig wallets, and system breaches, rather than outdated encryption,” said CEO & Co-founder of Quranium, Kapil Dhiman. “That’s why QSafe exists because users deserve a wallet that evolves with threats; a wallet that gives you full control, clarity, and confidence no matter what chain or token you’re using.” 

Key Features of QSafe Wallet

  • Quantum-safe signatures – Every transaction is signed using SLH-DSA to ensure resilient against quantum attacks.
  • Seamless crypto ↔ fiat access – Buy and sell crypto directly in any national currency, with full KYC integration for secure compliance.
  • Encrypted backup protection – Wallet recovery data is encrypted using ML-LEM to keep it safe, even decades from now.
  • True cross-chain compatibility – Manage assets across Bitcoin, Solana, Ethereum, Quranium, and more with a single wallet.
  • User-friendly experience – Simple, intuitive UX built for everyone; from first-time users to experienced crypto traders.
  • Self-custody first – You hold your keys, your assets, and your future. No intermediaries.
  • Uncrackable by design – QSafe is built to withstand not just today’s risks but tomorrow’s supercomputers. 

Getting Started is Fast and Simple

Available as a browser extension on Chrome, Firefox, Windows, macOS, and Linux, users can set up QSafe in minutes. Users can easily get started by creating or restoring a wallet, setting a secure password, generating SLHDSA and ML-KEM keys, and sending their first quantum-secure transaction on the Quranium Chain, all in just a few simple steps.

Why QSafe, Why Now?

Most crypto wallets today still rely on classical encryption standards like ECDSA and SHA-256. These standards, while robust against classical computing threats, are vulnerable to the emerging capabilities of quantum computing.

As of the end of 2024, Bitcoin’s market dominance stood at approximately 53.6%, while Ethereum’s market share had declined to around 11.8%, according to CoinGecko’s Annual Crypto Industry Report. Combined, these two cryptocurrencies represent a significant portion of the $3.91 trillion total crypto market capitalization.

The threat posed by quantum computing is not merely theoretical. According to Deloitte, nearly 25% of Bitcoin addresses are already exposed, making them a potential jackpot for any quantum system capable of reverse-engineering private keys. This vulnerability underscores the pressing need for quantum-resistant solutions in the crypto space.

Moreover, quantum computing advancements are accelerating. While current quantum computers have around 100 qubits, breaking ECDSA encryption would require approximately 1,500 logical qubits. Though this threshold hasn’t been reached yet, projections suggest that such capabilities could emerge within the next decade, emphasizing the urgency for proactive security measures.

QSafe addresses these challenges head-on by integrating post-quantum cryptographic algorithms, giving users the confidence that their digital assets remain secure in the face of evolving technological threats. 

“QSafe isn’t just reacting to the quantum threat, it’s architected to withstand it,” added Dhiman, “You don’t hire a security guard after the theft has happened. You hire one to prevent it. QSafe is designed to protect your assets before quantum threats ever reach your keys.”

While timelines for cryptographically relevant quantum computers (CRQCs) range from 2030 to 2040, the window for proactive defense is now. And that’s exactly what QSafe delivers: post-quantum signatures, encrypted backups, and full control before the risks become real.
