First Quantum-Safe MPC enterprise wallet Infrastructure
First production ready post-quantum- MPC wallet built on NIST approved ML-DSA signature scheme for enterprise digital asset custody
DESIGN PARTNERS
Threshold Post-Quantum Cryptography
The world’s first production implementation of MPC on ML-DSA.
The private key is never combined, Multiple parties each hold a secret share and collaboratively produce signatures
The result: distributed MPC security combined with NIST-standardized quantum resistance.
Secure Enclaves & Hardware Isolation
Each key share is generated, stored, and used exclusively within hardware-isolated, encrypted memory regions (Intel SGX, ARM TrustZone).
Even if an attacker gains root access to the server, they cannot extract or misuse the key share.
Provides defense against malware, remote attacks, and malicious insiders.
Transaction Intent Verification
Before any signature is created, each MPC node independently verifies the transaction against immutable policies.
Multi-user approvals, spending limits, whitelisted addresses, and time-based restrictions.
If a transaction violates policy, the nodes refuse to sign
A new generation of threats demands a new generation of security.
The Quantum Imperative
Q-Day is projected within 5 years. NIST finalized post-quantum standards in August 2024, urging immediate migration.
Harvest Now, Decrypt Later
Adversaries are actively capturing encrypted data today, stockpiling it for decryption once quantum computers arrive.
Blockchains Have Started Moving
Major blockchain networks are planning and moving towards building quantum resistance
The quantum threat to digital assets is not a distant concern—it’s an imminent reality requiring immediate action. At Silence Laboratories, we’ve engineered the definitive solution: a post-quantum MPC vault that provides cryptographic assurance for the next century of digital finance.
