BitGo Launches Four Bitcoin Wallet Tools to Prepare for Future Quantum Threats

Highlights:

• BitGo introduced new wallet tools that help institutions prepare for threats before quantum computing becomes a real risk.
• The new security features help institutions identify exposed Bitcoin addresses and move funds into safer wallets.
• Quantum computers cannot break Bitcoin today, but more blockchain projects are already preparing for future security challenges.

BitGo announced four new security tools in a July 22 product update to help institutions prepare Bitcoin wallets for future quantum computing risks. The company released the features for supported institutional Bitcoin multisignature wallets. BitGo said the update helps institutional clients measure and reduce public-key exposure before quantum computers become capable of threatening Bitcoin security.

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. That exposure is the part worth measuring today.

The release introduced a Quantum Risk Score, a Fix Exposed Addresses workflow, a new UTXO selection method, and updated address controls for supported wallets. BitGo designed the features to improve institutional wallet management while leaving Bitcoin’s existing consensus rules unchanged. The company also said the release helps institutions prepare today, but any network-wide quantum protection will still require a future Bitcoin protocol upgrade.

BitGo’s quantum risk score measures how much public-key exposure supported institutional wallets currently have inside the BitGo platform. However, BitGo has not disclosed how it calculates the Quantum Risk Score or how it classifies different exposure levels. The company also has not published the score’s weighting system, thresholds, or methodology for assigning risk levels.

Most standard Bitcoin outputs reveal their public keys after users spend funds because the network must verify each transaction signature. Address reuse or partial spending can leave additional Bitcoin connected to the exposed public key and increase future quantum risk. A cryptographically relevant quantum computer could eventually derive private keys from exposed public keys if the technology reaches that capability.

Understanding BitGo Quantum Threats for Bitcoin Wallets

BitGo introduced new wallet management features that help institutions reduce long-term public-key exposure after spending Bitcoin from supported wallets. The new UTXO selection method groups Bitcoin by address during transactions to avoid leaving exposed outputs behind. When a wallet spends one output, it also selects every other output from that address to reduce future public-key exposure.

The Fix Exposed Addresses workflow moves Bitcoin from exposed addresses into newly generated addresses so future transactions use fresh public keys. Those new Bitcoin addresses keep their public keys hidden until users spend funds from them for the first time. BitGo also updated its default address controls to reduce transaction patterns that expose Bitcoin public keys sooner than necessary during normal wallet activity.

BitGo currently limits the new security controls for quantum threats to supported institutional Bitcoin multisignature wallets. The company has not disclosed how many clients can access the release. It also has not announced pricing or when it will expand support to more customers. Instead, BitGo focused the update on helping institutional clients reduce future public-key exposure through stronger wallet management.

More Bitcoin Projects Prepare for Quantum Risks

BitGo’s release adds to broader Bitcoin efforts that focus on reducing future risks from quantum computing before practical attacks emerge. Earlier this year, BitGo and Silence Laboratories tested post-quantum signing inside an institutional custody workflow.

BitGo and @silencelabs_sl completed the first post-quantum MPC transaction simulation last Friday.

Meanwhile, Bitcoin developers are reviewing BIP 360, a draft proposal that aims to reduce long-term quantum exposure. The proposal introduces Pay-to-Merkle-Root outputs that remove Taproot’s key-path spend to reduce long-term public-key exposure.

Nine companies also committed $15 million over three years to a Bitcoin security consortium that prioritizes post-quantum research. Ethereum Foundation researcher Nicolas Consigny also proposed account-level post-quantum protection that costs about $0.07 per account without changing Ethereum’s core protocol.

Meanwhile, the Algorand Foundation released a roadmap on June 18 that targets network-wide quantum resilience by the end of next year. Michael Saylor also warned that BIP 110 could create an unwanted precedent for future Bitcoin consensus changes.
