Why read samczsun?

samczsun's price-oracle guide shows how a protocol can turn an apparently ordinary market price into an exploitable assumption. He walks through mechanisms and incident examples, making it useful for understanding what a contract trusts and how an attacker can influence that input. It is a concrete starting point for readers moving from using DeFi to examining how it works.

His later writing broadens the problem beyond a contract's source code. The North Korean threat article examines infrastructure and human access, while the bounty essay asks how to keep deployed systems under active review. These pieces connect exploit research to the work of Security Alliance, which he founded after his research role at Paradigm.
