Firms are deploying post-quantum cryptography in wallets as Bitcoin and Ethereum network upgrades lag, targeting a 2030 threat deadline.
Crypto companies are accelerating the adoption of quantum-resistant wallets to protect user assets before Bitcoin and Ethereum networks implement core protocol upgrades. The push comes amid concerns that blockchain-level changes could take years, leaving wallets vulnerable to quantum computing threats expected as early as 2030.
Firms like Silence Laboratories are integrating algorithms such as ML-DSA, approved by NIST, into multi-party computation (MPC) signatures for institutional wallets. Other NIST-endorsed algorithms, including SPHINCS+, Falcon, and CRYSTALS-Dilithium, are being evaluated for distributed signing systems. Experts warn that user behavior and coordination gaps may slow widespread adoption.
The timeline for quantum threats has compressed, with recent estimates suggesting a potential breach risk by 2030. While blockchains remain exposed, wallet providers are prioritizing near-term security upgrades to mitigate risks.
