• BitGo has introduced quantum-risk scoring, smart UTXO selection and remediation tools to help institutions assess Bitcoin wallet exposure.
• The new capabilities strengthen multi-signature wallet management by improving address security and reducing onchain public key exposure.
• The tools enable institutions to proactively prepare for future quantum computing risks while maintaining existing Bitcoin custody security standards.

BitGo has introduced a suite of quantum risk management tools for institutional Bitcoin wallets, aiming to help clients identify, assess and reduce potential exposure to future quantum computing threats before they become a practical concern.

The tools expand BitGo's multi-signature custody platform with operational controls designed to improve wallet security, strengthen address management and reduce public key exposure across UTXO-based Bitcoin wallets, according to a statement on Thursday.

Quantum-risk tools target future computing threats

The launch comes as concerns grow over the long-term implications of quantum computing on cryptocurrency protocols. While quantum computers capable of breaking Bitcoin's cryptography do not yet exist, security experts have increasingly urged institutions to prepare well in advance for the possibility.

"BitGo is investing in the foundation required for a post-quantum future for our clients," said BitGo CEO and co-founder Mike Belshe.

The firm noted that its multi-signature wallet architecture already minimizes unnecessary key exposure by using strict address hygiene and generating new addresses for Bitcoin transactions. The latest release adds new tools that provide institutions with greater visibility into wallet exposure and workflows for reducing potential risks at scale.

BitGo expands wallet risk management capabilities

Among the new features is a Quantum Risk Score that measures potential quantum-related exposure across supported Bitcoin wallets. The platform also introduces a smart UTXO selection method that groups and prioritizes unspent transaction outputs by address, helping reduce exposure that can arise from partial Bitcoin spends.

"We believe the safest key is one whose public key has never been revealed onchain. These capabilities give institutions a practical way to understand and reduce quantum exposure while continuing to rely on the proven security of multi-signature,” Belshe added.

BitGo has also added a guided "Fix Exposed Addresses" workflow, allowing institutions to move funds from addresses with elevated exposure into newly generated addresses with improved key hygiene.

In addition, updated default address-type controls are designed to reduce reliance on Bitcoin address formats and transaction patterns that may introduce additional quantum-related considerations.

The company noted that the tools are intended to complement, rather than replace, future protocol-level upgrades that could introduce post-quantum cryptographic protections to the Bitcoin network.

"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," Blockstream co-founder Adam Back stated.

BitGo noted that the new capabilities apply to supported UTXO-based assets and multi-signature wallet configurations, enabling institutions to proactively manage address-level risks using currently available technologies.
