BitGo adds 4 quantum controls for Bitcoin wallets

BitGo detailed four quantum-risk management controls for institutional Bitcoin wallets in a July 22 product announcement, aiming to measure and reduce public-key exposure before quantum attacks become practical. Summary Four new BitGo controls score exposure, consolidate UTXOs, remediate addresses, and adjust wallet defaults automatically. Bitcoin public keys become visible after spending, while Taproot outputs expose keys from their creation. No practical quantum attack can break Bitcoin today, leaving BitGo’s tools focused on operational preparation. The tools apply to supported Bitcoin multi-signature wallets. They include a Quantum Risk Score, a guided address-remediation workflow, a new UTXO selection method and updated default address controls. BitGo said the release supports operational preparation and does not replace any future Bitcoin protocol upgrade. You don't need to wait for quantum to become real to start managing the risk.Spending from a BTC address reveals its public key onchain.
