BitGo rolls out quantum protection for Bitcoin wallets as $2T crypto threat looms

BitGo Holdings Inc., the digital asset custodian listed on the New York Stock Exchange under the ticker BTGO, on Thursday introduced quantum-risk management tools for institutional Bitcoin wallets, giving clients a way to reduce on-chain key exposure before quantum computers capable of breaking encryption become operational.

"The safest key is one whose public key has never been revealed on-chain," Mike Belshe, chief executive officer and co-founder of BitGo, said in a statement. "These capabilities give institutions a practical way to understand and reduce quantum exposure while continuing to rely on the proven security of multi-signature."

The new features include a UTXO selection method that groups and prioritizes unspent transaction outputs by address to reduce exposure from partial spends, an in-platform quantum risk scoring system, a guided remediation workflow to move funds away from exposed addresses, and default address-type controls designed to reduce reliance on Bitcoin address patterns that may introduce additional quantum-related considerations. The tools apply to supported UTXO-based assets and multi-signature wallet configurations.

The launch comes as the broader cryptocurrency industry confronts what many executives describe as an existential threat. Research from Alphabet Inc.'s Google, published in March, suggested quantum computers may be able to break conventional cryptography sooner than previously expected, with the company saying machines capable of cracking encryption could arrive by 2029 — a timeline roughly a decade earlier than prior estimates. The $2 trillion global cryptocurrency market is built on blockchains secured by elliptic-curve cryptography, and Bitcoin's 17-year transaction history has generated a large number of visible public keys that could be vulnerable to a sufficiently powerful quantum computer.

"Nobody has a quantum computer that can touch Bitcoin today, but that's exactly why the work should start now, while it's calm and optional rather than urgent and forced," Adam Back, co-founder and CEO of Blockstream, said in the announcement.

BitGo's approach focuses on reducing address-level exposure using tools available today rather than waiting for future Bitcoin protocol-level post-quantum signature upgrades. The company said the controls are not a substitute for such upgrades but are designed to help institutions manage quantum-related risk at scale in the interim. Rival custodians and blockchain developers are drawing up similar plans, though none of the top 20 blockchains have yet implemented a post-quantum signature algorithm, according to executives interviewed for this story.

The engineering challenge of migrating to post-quantum cryptography could take years. One senior cybersecurity executive at a major crypto firm said he expects it will take two years for his company to become fully quantum-resistant, describing the potential work as akin to a Y2K-style overhaul. The Ethereum Foundation, which supports the blockchain underpinning ether, the second-largest cryptocurrency, has said it is targeting 2029 for full protection from quantum computing.
