According to Decrypt, Europol has warned that cryptocurrency wallets represent the primary risk related to potential quantum computing threats. The European law enforcement agency stated that blockchains and associated wallet infrastructure may be vulnerable if quantum-capable computers become capable of efficiently solving cryptographic problems currently securing digital assets.
Europol noted that it expects blockchain networks and related systems to adapt in response to this emerging threat. A separate Europol report also assessed the risk that data stolen today—such as private keys or encrypted wallet information—could be decrypted later if strong quantum-resistant methods are not implemented.
The agency did not specify timelines for when quantum threats might materialize, nor provide estimates on how many wallets or systems could be affected. It emphasized preparedness and proactive adaptation as priorities for blockchain developers and custodial providers within the EU.
