BitGo rolls out quantum-risk management tools to shield institutional Bitcoin wallets

BitGo, one of the longest-running institutional custody providers in crypto, has fully deployed a suite of quantum-risk management tools designed to keep Bitcoin public keys from being exposed on-chain. The rollout, which completed on July 22, introduces four new security controls that work within BitGo’s existing multi-signature wallet framework, requiring no protocol changes and no new tokens. The central idea is deceptively simple: if a public key has never been revealed on the blockchain, a quantum computer can’t use it as an attack vector. BitGo’s new tooling is built around making that principle practical at institutional scale. What BitGo actually built The update centers on four principal controls. The most visible is the Quantum Risk Score, an exposure metric baked directly into the BitGo platform that gives users a real-time read on how much of their holdings sit behind already-exposed public keys. There’s also a guided workflow that helps users move funds from compromised addresses to fresh ones, reducing the attack surface without requiring deep technical knowledge. On the transaction level, BitGo developed a UTXO selection method that limits public-key exposure during ...
