Quranium: ETH, BTC and Solana Wallet Extension

Quranium: The Multichain Quantum-Safe Wallet
Secure Your Digital Future with Quranium - The First Multichain Quantum-Safe Wallet Powered by Native Quranium Chain Integration.

In an era where quantum computing threats loom large, Quranium emerges as a pioneering Chrome extension, offering unparalleled security for your digital assets. We are proud to introduce the world's first multichain wallet with a deeply integrated, native Quranium blockchain, fortified with cutting-edge Post-Quantum Cryptography (PQC).

Built for the Quantum Age:

Quranium is engineered from the ground up to safeguard your cryptocurrencies against the potential of quantum attacks. We leverage the robust security of:  

SLH-DSA (SPHINCS+) for Digital Signatures: Chosen for its strong cryptographic foundation rooted in hash functions, SLH-DSA provides provable security against both classical and quantum adversaries. This ensures the integrity and authenticity of your transactions in a post-quantum world.
ML-KEM (Module Learning with Errors Key Encapsulation Mechanism): For encrypting and securely exchanging cryptographic keys, Quranium utilizes ML-KEM. This lattice-based algorithm, standardized by NIST, offers a high level of resistance against quantum attacks, protecting your sensitive data and communication.  
PK Modules (Probabilistic Key Modules): Enhancing the security of your private keys, Quranium employs advanced Probabilistic Key Modules. This innovative layer adds entropy and complexity, making key extraction significantly more difficult, even for sophisticated attack vectors.
Seamless Multichain Experience:

Quranium isn't just about quantum security; it's about providing a user-friendly and versatile multichain experience. Manage your assets across a growing ecosystem of blockchains, all within a single, secure Chrome extension. Our initial integration includes:

Bitcoin (BTC): Securely store and transact with the world's leading cryptocurrency, with future quantum-safe transaction options planned.
Ethereum (ETH) & EVM-Compatible Chains: Interact with the vast Ethereum ecosystem and other EVM-compatible networks like Binance Smart Chain (BSC), Polygon (MATIC), Avalanche (AVAX), and more. Quranium provides a unified interface for managing your ERC-20 tokens and participating in DeFi.  
More Chains Coming Soon: We are actively working to integrate additional popular blockchains, expanding your reach and asset management capabilities within Quranium.
