Currently the ONLY wallet that can make this claim.
While your Bitcoin still uses ECDSA (required by the Blockchain), XColdPro wraps your private keys in an additional layer of AES-256 Encryption.
AES-256 is quantum-resistant – even Grover’s algorithm only reduces it to AES-128 strength, still unbreakable.
Seed Phrase Quantum Protection
Your BIP39 seed is encrypted using Argon2id (memory-hard, quantum-resistant) combined with ChaCha20-Poly1305 (symmetric, quantum-safe).
Even if quantum computers break ECDSA tomorrow, they can’t extract your seed from XColdPro’s encrypted storage.
The Critical Difference
Other wallets store private keys using the SAME elliptic curve cryptography that quantum will break. When ECDSA falls, their storage falls. XColdPro uses quantum-resistant symmetric Encryption for storage, only converting to ECDSA at Transaction Signing time.
Why This Matters:
When quantum computers break ECDSA in ~10 years:
Keys extracted, funds stolen
Keys remain encrypted with quantum-proof AES-256, safe until blockchains upgrade to post-quantum signatures
AES-256 Encrypted (Quantum-Safe)
Private Keys
ChaCha20 Encrypted (Quantum-Safe)
Only at signing
Convert to ECDSA (Required by Blockchain)
Bottom Line
XColdPro separates storage Encryption (quantum-resistant) from Blockchain signatures (not quantum-resistant yet), giving you a migration path that others don’t have.
