Supply chain compromise is the quiet failure mode that bypasses audits, bypasses best practices, and lands straight in production through build tools, dependencies, CI runners, […]

Proxy-Based Honeypots: Upgradeable Contract Traps (Complete Guide) Proxy-Based Honeypots are one of the cleanest “looks safe today, becomes a trap tomorrow” patterns in crypto.

A proposal gets posted, votes get cast, a timelock expires, and a change executes. The chain records it as normal governance, but the outcome can still be malicious: a treasury drained, an

DeFi Attacks: MEV Sandwiching Explained, Detection Signals, and Mitigations DeFi Attacks do not always look like a contract exploit or a drained wallet.
