Cryptocurrency Security

Cryptocurrency security spans private keys, wallets, transaction protocols, open-source supply chains and the protection of physical assets. A series of vulnerabilities and thefts has recently hit ecosystems including Ethereum, Solana and Zilliqa, with losses to hackers in 2026 approaching or exceeding $1 billion. North Korean hackers, AI-enabled scams and home invasions involving coercion have also expanded the attack surface beyond on-chain systems to software and personal safety. As the industry turns to hardware security modules (HSMs), continuous monitoring, operational governance and quantum-resistant technology, these developments warrant close attention to assess whether defenses can keep pace with evolving risks.
