BTC BitGo launches quantum-focused wallet control based on multi-signature security
BitGo announced new quantum risk management capabilities for Bitcoin wallets. This release adds quantum risk scores, 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 customers.
BitGo Holdings, Inc. (NYSE: BTGO) confirmed that this release is an extension of its long-term wallet security model. The company is known for its multi-signature hosting, a structure designed to eliminate single points of failure. This announcement integrates quantum focusing tools directly into the same framework.
The core of the release is the Quantum Risk Score, a scoring system built into the BitGo platform that allows institutions to assess the risk exposure levels of supported Bitcoin wallets in a one-stop manner. Customers can identify which addresses are at higher risk because the public key is already visible on the chain. This score can be used without changing existing hosting arrangements.
In conjunction with the scoring, BitGo launched a guided remediation workflow called \"Repair Exposed Addresses\". The tool guides customers to transfer funds from high-risk addresses to newly generated addresses. The new address follows improved key hygiene practices from the beginning. For organizations that manage large wallets, this significantly reduces manual operations.
Mike Belshe (CEO and co-founder of BitGo) explained the logic behind the release: \"We believe that the most secure key is one whose public key has never been exposed on the chain. These capabilities provide institutions with a practical way to understand and reduce quantum exposure while continuing to rely on the mature security of multiple signatures.\"
Additional tools for UTXO processing and wallet defaults
In addition to risk scoring, BitGo has announced a new UTXO selection method that aims to reduce exposure from some expenses. This method groups and prioritizes unspent transaction output by address rather than processing it individually. This limits the frequency with which the public key is exposed during normal wallet activity. BitGo makes it clear that certain address types, such as Taproot and Pay-to-Public-Key, expose public keys at the time of creation and are therefore outside the scope of the tool. Funds in these address types require separate remedies.
At the same time, BitGo also announced updated default address type controls. These changes adjust the default behavior of the new wallet, reducing reliance on patterns related to quantum exposure. BitGo positions this update as a supplement to, rather than a replacement for, future protocol-level changes.
Adam Back (co-founder and CEO of Blockstream and BSTR) commented on the release timing: \"There are currently no quantum computers that can touch Bitcoin, but for this reason, the work should start now, while it is calm and optional, rather than urgent and forced.\" Belshe expressed a similar view: \"We don\'t believe that institutions need to wait for quantum events to occur before they can start managing quantum risk. The right thing to do is to reduce exposure now, strengthen wallet operations, and prepare for the migration from the current security model to a future post-quantum standard.\"
BitGo insists that institutions do not need to wait for actual quantum events to occur before taking action. The announcement positions quantum risk management as daily operational hygiene and is a step in the migration process to backward quantum wallet standards.
