About QuantumSafe
Post-quantum cryptography for blockchain, built by a KOSDAQ-listed company.
Our Mission
Protect blockchain assets from the quantum threat by making post-quantum cryptography accessible to every developer. We believe the transition to quantum-safe cryptography should be seamless, affordable, and built on open standards — specifically NIST FIPS 204 (ML-DSA) and FIPS 205 (SLH-DSA).
The Harvest Now, Decrypt Later (HNDL) threat means adversaries are already collecting blockchain data today. With quantum computers projected to break ECDSA between 2030–2035, the migration window is closing. QuantumSafe provides the tools — free wallet scanning, PQC key generation, and hybrid attestation — to begin that migration now.

Company Timeline
Why a Materials Company?
Korea Advanced Materials has 25+ years of expertise in photonics and semiconductor technologies — the physical foundation of both quantum computing hardware and quantum-safe communication systems. This is not a pivot but a natural extension.
Photonics research involves understanding quantum phenomena at the physical layer: single-photon detection, quantum key distribution (QKD), and optical computing architectures. QuantumSafe bridges this deep hardware knowledge into the software cryptography space — bringing physical-layer security intuition to practical blockchain protection.
As a KOSDAQ-listed company with regulatory oversight and financial transparency obligations, we offer the institutional trust that enterprise blockchain security requires — unlike typical startup-stage crypto security tools.
Open Source Commitment
Our TypeScript and Python SDKs are MIT-licensed and open source. We believe cryptographic security tools must be auditable and transparent. By opening our client-side implementation, developers can verify that private keys never leave their environment and that all cryptographic operations follow the NIST standard specifications exactly.
