Silence Laboratories has launched a commercial digital asset vault engineered to withstand attacks from future quantum computers, positioning the firm as a responder to escalating cybersecurity threats. The new vault integrates ML-DSA, the post-quantum digital signature standard finalized by the U.S. National Institute of Standards and Technology in 2024, with existing Multi-Party Computation systems. This addresses a critical vulnerability, as many current MPC-based custody solutions still rely on signature schemes susceptible to quantum breaches. “Digital asset custody already depends heavily on Multi-Party Computation, 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. Silence Laboratories’ infrastructure allows institutions to upgrade to quantum-safe security without abandoning their current MPC security model, offering a less disruptive path to enhanced protection.

This proactive step positions the company as a leader in a security arena rapidly demanding quantum resilience, as institutions grapple with the implications of increasingly powerful computational capabilities. Silence Laboratories’ infrastructure distinguishes itself by enabling firms to upgrade security protocols without a complete overhaul of existing systems, a critical advantage for organizations already invested in complex security architectures. The new vault combines ML-DSA with MPC, distributing signing authority across multiple parties to enhance security while simultaneously adopting cryptography designed to resist attacks from quantum computers. This hybrid approach allows institutions to maintain the operational benefits of MPC, such as distributed control and governance, while fortifying their defenses against a potentially disruptive technological shift. Beyond the post-quantum signature scheme, Silence Laboratories further enhances security by running MPC-TSS key-share operations within Google Cloud Confidential Computing and similar Trusted Execution Environments.
This layered approach isolates critical processes in hardware-protected environments, minimizing exposure to risks associated with cloud infrastructure, host systems, and operator vulnerabilities. The company’s PQ-MPC wallet infrastructure is currently available to design partners including Bitgo, EigenLayer, Networks for Humanity, Zengo, Bron and Infosys, signaling a commitment to collaborative implementation and real-world testing of this crucial technology. Bytes added, “Using our quantum-safe MPC infrastructure, institutions can begin upgrading now, on their own timeline.”
Beyond the cryptographic advancements, Silence Laboratories is utilizing hardware-protected environments within Google Cloud Confidential Computing to further isolate critical key-share operations; this layered security model minimizes exposure to risks originating from cloud infrastructure, host systems, or even malicious operators. This means that even if a cloud environment is compromised, the cryptographic keys remain protected within the confidential computing enclave.
