Silence Labs Launches Quantum-Safe Vault to Secure Crypto Custody

Silence Laboratories has launched a quantum-safe custody vault designed to protect digital assets from future cryptographic threats. The system combines post-quantum signatures with multi-party computation to help institutions transition without overhauling existing infrastructure.

Key Takeaways:

• Silence Laboratories launched a quantum-safe vault using NIST’s 2024 ML-DSA standard.
• Bitgo and Infosys join early tests, signaling rising institutional focus on quantum risk.
• Silence Labs targets gradual adoption, with MPC upgrades to prep crypto for future threats.

Infosys Backs Silence Labs Vault as Firms Test Quantum-Resistant Custody Model

Silence Laboratories has introduced what it describes as the first quantum-resistant vault for digital asset custody, marking an early attempt to address a risk that many in the industry still consider years away but increasingly unavoidable.

According to an exclusive shared with Bitcoin.com News, the new system is built to safeguard crypto assets and transaction signing against the potential impact of quantum computing. While such machines are not yet capable of doing so at scale, recent advances and the rollout of post-quantum standards have begun to shift the conversation from theory to preparation.

Silence’s approach centers on combining multi-party computation, or MPC, with post-quantum cryptography. MPC is already widely used in institutional custody, allowing multiple parties to share control over private keys rather than relying on a single point of failure. The company’s new infrastructure retains that model while replacing traditional signature schemes with ML-DSA, a quantum-resistant algorithm standardized by the U.S. National Institute of Standards and Technology in 2024.

The aim is to allow financial institutions to upgrade their security gradually. “Most existing systems still rely on signature schemes that were not built to withstand quantum threats. Using our quantum-safe MPC infrastructure, institutions can begin upgrading now, on their own timeline, rather than being forced into a rushed migration later,” said Andrei Bytes, Co-founder and CTO of Silence Laboratories.

The vault also incorporates trusted execution environments, such as Google Cloud Confidential Computing, to isolate sensitive operations. These hardware-protected environments are designed to reduce exposure to risks from cloud providers, system operators, or external attackers.

Modular Structure Enables Scale for Quantum-Safe Vault

Silence said the platform is modular, meaning it can integrate with existing governance and policy frameworks used by banks, custodians, and crypto platforms. That flexibility may be critical for large institutions, where replacing core infrastructure can be slow and costly.

The product is being rolled out initially to a group of design partners that includes Bitgo, Zengo, Eigenlayer, and Infosys, among others. These early adopters are expected to test how the system performs in real-world custody workflows and help refine its deployment.

For now, the technology remains a safeguard against a hypothetical threat. But for institutions managing large pools of digital assets, the cost of waiting could be high. Silence Laboratories is betting that early preparation will prove less disruptive than a rushed transition later.
