Quantum attacks pose a real threat to crypto holders today. The 'harvest now, decrypt later' vulnerability—where attackers intercept and store encrypted data now, waiting for quantum computers to break the encryption—has become a genuine concern for long-term security. Qastle steps in as a solution: the first quantum-resistant hot wallet leveraging Quantum eMotion's true random number generator (QRNG) technology to fortify your private keys against future quantum threats. The wallet's already rolled out across iOS and Android app stores globally, with the mainnet officially launching on January 3, 2026. This marks a significant milestone for quantum-safe infrastructure in the Web3 space—combining practical usability with next-generation cryptographic protection. Whether you're managing smaller holdings or serious positions, having a quantum-secure layer adds genuine peace of mind in an era where security standards are rapidly evolving.
