BitGo Unveils Quantum Risk Controls for Institutional Clients Amid Growing Exposure Concerns

BitGo has launched four new quantum risk management controls for Bitcoin wallets, aimed at institutional clients using supported multi-signature wallets. The move targets a scenario where a future quantum computer could potentially derive private keys from public keys, exposing funds to theft.

The Quantum Risk Score gives clients an in-platform metric of their exposure, with the score based on how many unspent outputs have visible public keys. However, the formula and thresholds for this score are undisclosed by BitGo, making it a proprietary internal risk indicator rather than an independently verifiable security standard.

BitGo's new controls also include guided address remediation, a revised UTXO selection method to prevent partial spends from leaving exposed coins behind, and updated default address settings to reduce reliance on output types that create early key visibility. However, Taproot and Pay-to-Public-Key outputs are not yet covered by the current release and require separate remediation workflows.

The move is seen as operational preparation rather than an emergency response, with Blockstream co-founder Adam Back stating 'nobody has a quantum computer that can touch Bitcoin today.' The point is precisely that institutions shouldn't need an active threat to start managing the risk, the time to reorganize exposure is while it's still theoretical.
