Crypto Firms Race to 'Quantum-Proof' Wallets Before Bitcoin, Ethereum Networks Catch Up

As concerns around quantum computing continue to grow, crypto firms are accelerating efforts to strengthen wallet and custody security before future threats become a reality. Many in the industry believe upgrading blockchain networks such as Bitcoin and Ethereum at the protocol level could take significant time, leaving user wallets potentially vulnerable in the interim. Some experts even predict that the so-called “Q-Day,” when quantum computers could crack existing cryptographic systems, may arrive as early as 2030.

One company focusing on post-quantum wallet protection is Silence Laboratories. The company recently introduced support for distributed signature systems based on multi-party computation (MPC) using ML-DSA, a cryptographic standard selected by the National Institute of Standards and Technology (NIST).

According to CEO and co-founder Jay Prakash, the company’s work aligns with NIST’s recent approval of post-quantum algorithms such as SPHINCS+, Falcon, and CRYSTALS-Dilithium. Over the past several months, the team evaluated how these algorithms perform in distributed signing environments commonly used by institutional wallets and custodians.

Prakash explained that not every approved algorithm is equally suitable for MPC systems, especially when factors like transaction efficiency, signature size, and computational performance differ across blockchain networks. He noted that fragmentation may emerge as different chains adopt different cryptographic methods.

The company’s MPC-based design splits cryptographic keys into separate shares distributed across isolated nodes. Transactions are then signed collaboratively without reconstructing the original key, reducing exposure to attacks from future quantum computers. This model has gained traction among institutions, which increasingly prefer distributed security systems over centralized key storage.

MPC architecture is already widely used by custodians and enterprise wallet providers because it divides private keys across multiple devices for added protection. Silence Laboratories stated that its new solution can integrate into existing MPC infrastructure with minimal disruption, allowing organizations to transition toward post-quantum security through software-level updates rather than major operational changes.

Prakash also noted that the upgrade process remains seamless for end users. Developers can implement the enhanced cryptographic algorithms within wallet software development kits (SDKs), enabling platforms such as MetaMask to deliver improved security without altering the user experience.

The broader crypto industry remains divided on how to tackle the quantum computing challenge. While some companies prioritize wallet-level improvements, others argue that full protection will only come from protocol-level changes to blockchain networks themselves.

Several firms are exploring alternative approaches. Developers at Postquant Labs are working on a system that introduces quantum-resistant signatures to Bitcoin through an additional smart contract layer, avoiding direct modifications to the core protocol. Meanwhile, StarkWare researcher Avihu Mordechai Levy has proposed replacing Bitcoin’s elliptic-curve cryptography with hash-based signatures that function within the blockchain’s current framework, though the approach is considered expensive and difficult to scale.

Although quantum computers capable of breaking modern encryption have not yet been developed, rapid advancements in the field are increasing urgency across the crypto sector. Still, experts caution that wallet-level security enhancements alone may not be enough. As Prakash emphasized, if blockchain networks themselves do not eventually adopt post-quantum protections, upgraded wallets alone will not fully solve the problem.
