BitGo launched a tool to scan Bitcoin addresses for quantum-related public key exposure and help users migrate funds to quantum-resistant addresses.
Tech & Launches ·
BitGo has released a Quantum Resistance Score tool that evaluates Bitcoin addresses for exposure to quantum-related risks by checking whether their public keys have been revealed onchain. The tool requires no wallet connection or account creation and can scan multiple addresses using only public blockchain data. The score is expressed as a percentage, with 100% indicating no exposed public keys across submitted addresses and 0% indicating all keys are already exposed.
Public keys become permanently visible onchain when funds are spent from an address, creating the surface where future quantum computers could theoretically pose a threat. BitGo's analysis identifies which addresses carry this exposure and helps users prioritize migration to better-protected addresses. For BitGo clients specifically, the platform offers additional controls including default address-type settings on new wallets and a "Fix Exposed Addresses" workflow that sweeps funds from exposed addresses to newly generated ones while preserving wallet ownership and policies.
The tool functions at the address and transaction level but is not presented as a substitute for protocol-level post-quantum signature upgrades that may come to Bitcoin itself. The Quantum Resistance Score can shift over time as addresses transition from unexposed to exposed status through transaction activity, so regular monitoring is recommended.
