Quantum-Resistant DEX & Asset Shielding Protocol built on Uniswap v3/v4 architecture
CRYSTALS-Dilithium signatures and CRYSTALS-Kyber key encapsulation provide NIST Level 3 security against quantum attacks.
Purpose-built blockchain with QEVM (Quantum-resistant EVM) and QR-PoS consensus achieving 5,000+ TPS.
Based on Uniswap v3/v4 architecture with capital-efficient market making and custom price ranges for LPs.
Native conversion of classical assets (ETH, BTC, USDC) to quantum-resistant equivalents (qETH, qBTC, qUSDC).
Trustless bridge infrastructure with multi-validator consensus and fraud proof mechanisms for secure transfers.
Quantum-resistant token standard compatible with ERC-20 tooling while enforcing post-quantum cryptography.
The emergence of quantum computing threatens the cryptographic foundations of blockchain technology. QRDX addresses this existential challenge by introducing the first quantum-resistant decentralized exchange protocol with native asset shielding capabilities. Built on Uniswap v3 and v4 architecture principles and secured by NIST-standardized post-quantum cryptographic algorithms, QRDX enables users to shield traditional assets (e.g., ETH → qETH) into quantum-resistant equivalents while maintaining the efficiency and capital utilization of modern automated market makers (AMMs).
QRDX Chain serves as the foundational Layer-1 blockchain implementing post-quantum security primitives, enabling cross-chain asset migration, decentralized trading, and long-term cryptographic security. The protocol combines CRYSTALS-Dilithium for digital signatures and CRYSTALS-Kyber for key encapsulation, providing NIST Level 3 security guarantees while maintaining performance comparable to traditional blockchain systems.
Through innovative Quantum-Resistant Proof-of-Stake (QR-PoS) consensus and optimized implementations of post-quantum algorithms, QRDX achieves transaction throughput exceeding 5,000 TPS with sub-second finality. The protocol supports concentrated liquidity market making, cross-chain asset bridges, and the qRC20 token standard—a quantum-resistant equivalent of ERC-20.
This whitepaper presents the technical architecture, economic model, and security guarantees of the QRDX ecosystem, demonstrating how quantum-resistant cryptography can be practically integrated into high-performance DeFi protocols without sacrificing user experience or capital efficiency.
