BitGo Launches Wallet Tools to Measure and Reduce Bitcoin Quantum Risk

Overview

• BitGo announced on Thursday that it has added an in-platform Quantum Risk Score, a Fix Exposed Addresses remediation workflow, a UTXO selection method, and default address-type controls for UTXO-based wallets and multi-signature custody.
• The Quantum Risk Score rates on-chain public-key exposure so custodians can prioritize which addresses to remediate and the Fix Exposed Addresses flow guides moving funds into newly generated keys with stronger key hygiene.
• The UTXO selection change groups and prioritizes coins by address to limit how partial spends reveal public keys during normal operations, and default wallet settings now steer away from patterns that increase exposure.
• BitGo and industry figures stress that no practical quantum attack on Bitcoin exists today, and the company says these tools are an operational complement to, not a replacement for, future protocol-level post-quantum signature upgrades.
• The rollout covers UTXO-based address types only and excludes formats that reveal a public key on creation, such as Taproot, and reporting has estimated millions of bitcoin sit in addresses with exposed public keys though those figures vary.
