Silence Laboratories unveiled the world’s first quantum-safe vault designed for secure digital asset custody and transaction signing. The new vault leverages Silence Laboratories’ quantum-safe wallet infrastructure, which is designed to help banks, custodians, and crypto platforms begin preparing for a future in which quantum computers could compromise today’s widely used cryptographic standards.
The launch comes as quantum security risks move from a long-term research topic to a more immediate infrastructure concern. Advances in quantum computing, combined with the rollout of new post-quantum cryptography standards from the U.S. National Institute of Standards and Technology (NIST) are pushing security teams across industries to begin planning for the eventual replacement of existing cryptographic systems.
That shift carries particular urgency for digital asset firms. Much of today’s custody infrastructure relies on cryptography that remains secure against classical computers but is expected to become vulnerable to sufficiently advanced quantum machines. Silence Laboratories’ wallet infrastructure is designed to allow firms to begin the transition to quantum-safe infrastructure, without abandoning the MPC security model they already use today.
“Digital asset custody already depends heavily on Multi-Party Computation (MPC), but most existing systems still rely on signature schemes that were not built to withstand quantum threats” said Andrei Bytes, Co-Founder and CTO of Silence Laboratories. “Using our quantum-safe MPC infrastructure, institutions can begin upgrading now, on their own timeline, rather than being forced into a rushed migration later.”
Silence’s new wallet infrastructure combines ML-DSA, the post-quantum digital signature standard finalized by NIST in 2024, and MPC, a security model that distributes signing authority across multiple parties so no single actor ever controls the full key. This allows institutions to preserve the operational and governance benefits of MPC while moving to cryptography designed to withstand future quantum threats.
In addition to post-quantum signing, the new offering runs MPC-TSS based key-share operations inside Google Cloud Confidential Computing or similar Trusted Execution Environments, using isolated, hardware-protected environments designed to reduce exposure to cloud, host, and operator risk. The new PQ-MPC wallet infrastructure is modular and can be integrated with existing enterprise policy or governance layer applications.
Silence’s PQ-MPC wallet infrastructure is available immediately to select design partners, exploring post-quantum readiness for production custody workflows. Launch partners include BitGo, Networks for Humanity, Zengo, EigenLayer, and Bron wallet as wallet builders, and Infosys as a partner system integrator.
