How Long Until I Need a Quantum-Resistant Wallet?

The need for a quantum-resistant wallet exists now, not in the future. While quantum computers capable of breaking current cryptography may be 10-15 years away, the "harvest now, decrypt later" threat means cryptocurrency transactions made today with legacy cryptography are already potentially compromised.

Expert timelines for cryptographically relevant quantum computers (CRQCs) vary: conservative estimates suggest 2035-2040, moderate estimates 2030-2035, and optimistic projections 2027-2030. No consensus exists, but substantial resources are accelerating development globally.

The harvest timeline is immediate. Adversaries are collecting encrypted data and blockchain transactions now. When quantum computers become capable, this historical data becomes decryptable. Cryptocurrency on blockchain with exposed public keys from years ago becomes stealable.

Asset holding period matters. If you plan to hold cryptocurrency for 5+ years, the quantum threat window becomes significant. Assets intended for long-term storage or generational transfer face the full development arc of quantum computing.

Migration complexity increases under pressure. Moving assets calmly before quantum threats materialize is simpler than emergency migration when quantum capabilities are imminent. Network congestion, exchange availability, and market panic would complicate last-minute transitions.

No downside to early adoption. Using a quantum-resistant wallet today provides current security equivalent to or exceeding ECDSA while adding quantum protection. There is no security penalty for adopting post-quantum cryptography early.

SynX provides production-ready quantum resistance using Kyber-768 and SPHINCS+ today. Migrating now secures assets against the entire uncertain quantum timeline, eliminating the risk of being caught unprepared.
