New institutional controls introduce quantum-risk scoring and exposed-address remediation for Bitcoin multi-signature custody
BitGo Holdings, Inc. (“BitGo” or “Company”), the digital asset infrastructure company, announced new quantum-risk management capabilities for Bitcoin wallets, designed to help institutions assess, manage, and reduce quantum-related exposure across UTXO-based wallets.

The launch expands BitGo’s long-standing multi-signature security architecture with new operational tools for managing wallet-key exposure, improving UTXO handling, and strengthening institutional wallet operations as the industry prepares for a post-quantum future.
BitGo pioneered multi-signature wallets for Bitcoin and has long advocated for security models that reduce single points of failure. Its wallet architecture, strict address hygiene, and use of new addresses for Bitcoin transactions already help reduce unnecessary key exposure. The new capabilities give institutions additional visibility, controls, and workflows to manage quantum-related risk at scale.
“BitGo is investing in the foundation required for a post-quantum future for our clients,” said Mike Belshe, CEO and Co-founder of BitGo. “We believe the safest key is one whose public key has never been revealed on-chain. These capabilities give institutions a practical way to understand and reduce quantum exposure while continuing to rely on the proven security of multi-signature.”
While practical quantum attacks against Bitcoin are not available today, future advances in quantum computing could create risks for addresses whose public keys have been exposed on-chain. BitGo’s wallet management capabilities are designed to help clients reduce and eliminate that exposure before it becomes an operational issue.
“Nobody has a quantum computer that can touch Bitcoin today, but that’s exactly why the work should start now, while it’s calm and optional rather than urgent and forced,” said Adam Back, Co-Founder and CEO of Blockstream and BSTR.
BitGo’s quantum-risk management capabilities for Bitcoin wallets include:
- UTXO Selection Method: Our new coin selection method that groups and prioritizes UTXOs by address to reduce exposure created by partial spends. Funds already held in address types that expose a public key from creation, such as Taproot or Pay-to-Public-Key, require separate remediation and are outside of the scope of this application
- Quantum Risk Score: An in-platform scoring system that helps clients understand potential quantum-related exposure across supported Bitcoin wallets
- Fix Exposed Addresses Workflow: A guided remediation flow that helps clients move funds away from addresses with elevated exposure and into newly generated addresses with improved key hygiene
- Default Address-Type Controls: Updated default wallet behavior designed to reduce reliance on Bitcoin address types and transaction patterns that may introduce additional quantum-related considerations
These controls are not a substitute for future Bitcoin protocol-level post-quantum signature upgrades, but are designed to reduce address and transaction-level exposure using tools available today. The new capabilities apply to supported UTXO-based assets and multi-signature wallet configurations.
“We believe institutions do not need to wait for a quantum event to begin managing quantum risk,” added Belshe. “The right approach is to reduce exposure now, harden wallet operations, and prepare for the migration from today’s security models to future post-quantum standards.”
