‘Bunker mode’ is a far greater challenge for institutions than individual crypto holders

Project Eleven and Quantus are collaborating to develop institutional custody tools that protect cryptocurrency assets against future quantum-computing threats. The initiative aims to help financial institutions manage complex security migrations while maintaining strict audit and approval controls.
Why it matters
As quantum computing advances, the financial sector faces a critical need to secure digital assets against potential decryption, which is a significant hurdle for institutional crypto adoption.
However, for banks and custodians, the harder issue may be whether their key management, approval and audit systems can cope as different blockchains adopt varying quantum-resistant security standards.
Project Eleven, a company developing tools to protect crypto systems from future quantum-computing attacks, and privacy-focused proof-of-work blockchain Quantus plan to integrate Quantus with Project Eleven’s institutional custody platform, the companies told CoinDesk in an email statement.
The two companies are targeting the first quarter of 2027 for support that would let institutions manage Quantus keys and approve transactions through hardware security modules, internal policies and audit systems.
