TLDR:
BitGo announces Quantum Risk Score to measure exposure across Bitcoin wallet addresses.
New Fix Exposed Addresses workflow moves funds into keys with stronger hygiene practices.
UTXO selection method groups addresses by wallet to limit exposure from partial spends.
Belshe says safest key is one whose public key stays unrevealed on the blockchain.
BitGo is announcing new quantum risk management capabilities for bitcoin wallets. The launch adds a Quantum Risk Score, a guided workflow for exposed addresses, a new UTXO selection method, and updated default controls. These tools build on BitGo’s existing multi-signature architecture for institutional clients.
BitGo Rolls Out Quantum-Focused Wallet Controls Built On Multi-Signature Security
BitGo Holdings, Inc., trading as NYSE: BTGO, confirmed the launch as an expansion of its long-standing wallet security model.
The company built its reputation on multi-signature custody, a structure designed to remove single points of failure. This announcement adds quantum-focused tools directly into that same framework.
The centerpiece of the release is the Quantum Risk Score, a scoring system built into BitGo’s platform. It allows institutions to assess exposure levels across supported Bitcoin wallets in one place.
Clients can identify which addresses carry elevated risk due to public keys already visible on-chain. The score does not require a change to existing custody arrangements to be useful.
Paired with the score, BitGo introduced a guided remediation workflow named Fix Exposed Addresses. This tool walks clients through moving funds from higher-risk addresses into newly generated ones.
The new addresses follow improved key hygiene practices from the moment they are created. For institutions managing large wallet volumes, this removes much of the manual work involved.
Mike Belshe, CEO and Co-founder of BitGo, explained the reasoning behind the release. “We believe the safest key is one whose public key has never been revealed on-chain,” he said.
“These capabilities give institutions a practical way to understand and reduce quantum exposure while continuing to rely on the proven security of multi-signature.”
Additional Tools Target UTXO Handling And Wallet Defaults
Alongside the risk score, BitGo announced a new UTXO selection method aimed at reducing exposure from partial spends.
This method groups and prioritizes unspent transaction outputs by address instead of handling them separately. The approach limits how often public keys get revealed during normal wallet activity.
BitGo was clear that some address types fall outside this particular tool’s scope. Formats like Taproot and Pay-to-Public-Key expose a public key from the moment they are created.
Funds already held in those address types require separate remediation steps, a distinction BitGo highlighted directly in its announcement.
The company also announced updated default address-type controls as part of the same release. These changes adjust how new wallets behave by default, reducing reliance on patterns tied to added quantum-related exposure. BitGo positioned this update as a companion to future protocol-level changes rather than a substitute for them.
Adam Back, Co-Founder and CEO of Blockstream and BSTR, weighed in on the timing of the release. “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,” he said.
Belshe echoed that same view when describing the broader strategy behind the launch. “We believe institutions do not need to wait for a quantum event to begin managing quantum risk,” he added.
“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.”
BitGo maintained that institutions do not need to wait for an actual quantum event before acting. The announcement frames quantum risk management as routine operational hygiene, one step in a longer migration toward post-quantum wallet standards.
