Quantum-grade encryption

Your private keys are protected by post-quantum cryptography — engineered to resist the most powerful quantum computers, today and tomorrow.

Protection from “harvest now, decrypt later” attacks

Even if your wallet data is intercepted today, it stays encrypted forever. Attackers can’t “store now, decrypt later” when the encryption itself is quantum-resistant.

Security without compromise

Same familiar Web3 experience: send, receive, and trade with ease. But backed by the world’s most advanced encryption standard.
