“The strength of a man’s virtue should not be measured by his special exertions, but by his habitual acts.” — Blaise Pascal, Pensées.

The standard approach: analyze the smart contract source code. The problem: code can be rewritten, obfuscated, restructured. A fraudster adapts faster than a detector can be retrained. And the source code of 77% of contracts on Ethereum is not publicly available at all
