HACK3D: The Web3 Security Quarterly Report - Q2 2022

Web3 security losses exceeded $1.31 billion in H1 2026 across 344 incidents, with wallet compromise emerging as the most financially destructive attack vector and phishing shifting toward fewer, higher-value social engineering attacks.

This article analyzes that security model across the full asset-control lifecycle. It traces a single transaction through Clave's open-source implementation, surveys past vulnerabilities in WebAuthn, FIDO2, and CTAP, maps them onto the lifecycle of a typical Passkey Wallet, and ends with implementation checks for teams building one.

This report examines how future fault-tolerant quantum computers may compromise blockchain cryptography, and what protocols, validators, custodians, and ecosystem participants must do to migrate before the window closes.
