Postquant Labs Unveils Quip Network Quantum-Safe Bitcoin Wallet

Rapid advances in quantum computing threaten to break conventional cryptographic algorithms, posing serious risks of private-key exposure and security breaches for Bitcoin's unspent transaction output, or UTXO, model. Digital-asset custody infrastructure provider BitGo is seeking to help institutional clients guard against these future technological risks. The upgrade provides an important layer of protection for financial institutions holding large amounts of crypto assets over the long term.

BitGo formally launched quantum risk management for Bitcoin wallets on July 16, 2026, focusing on stronger UTXO transaction processing to reduce the risk of private-key exposure. The company also announced immediate support for the Ethereum layer-2 network Robinhood Chain, offering institutional-grade multisignature wallets and custody services to help financial institutions protect assets in the quantum era and broaden their multichain presence.

Bitcoin transactions rely on elliptic-curve digital signatures. A sufficiently powerful quantum computer running Shor’s algorithm could derive private keys from exposed public keys and steal assets. Replacing the signature mechanism would require network-wide consensus and asset migration, drawing attention to StarkWare’s upgrade-free approach as a fallback until longer-term changes such as BIP-360 are completed.

On April 9, 2026, StarkWare Chief Product Officer and BIP-360 co-author Avihu Levy published the QSB paper and open-source code. The system uses Bitcoin’s existing Script constraints and hash-based proofs to create quantum-resistant transactions without a soft fork or miner activation. Each transaction requires substantial offline GPU computation at an estimated cost of $75–$200, and the tool is currently intended for emergency recovery.

Most Bitcoin wallets currently rely on elliptic-curve cryptography. If large-scale quantum computers become capable of breaking signatures, funds tied to exposed public keys could be stolen, while an emergency upgrade could freeze assets that have not been migrated. A tool developed by Lightning Labs Chief Technology Officer Olaoluwa Osuntokun addresses a critical gap by allowing ordinary users to securely prove ownership and recover their funds.

As of July 20, 2026, Osuntokun had completed Bitcoin’s first working prototype of a quantum-resistant wallet rescue tool. The system allows users to submit proof of ownership without revealing their private-key seed and recover frozen funds once the network activates an emergency quantum-defense upgrade. The tool remains a prototype, and Lightning Labs has not announced a formal launch date or any amount of funds involved.
