Crypto security is facing a harsh reality — more than $17 billion has been stolen across 518 incidents over the past decade, with private key compromises emerging as one of the most damaging attack vectors. Data from DefiLlama shows that a significant portion of these losses comes from stolen credentials, phishing attacks, and weak wallet security rather than flaws in blockchain protocols themselves.

This shift highlights a growing vulnerability in the ecosystem. Even as smart contracts become more secure through audits and testing, attackers are increasingly targeting users directly. From brute-force attacks to phishing schemes targeting multi-signature wallets, the weakest link is often no longer the code — but the human and operational layer behind it.
