Warning signal

Suspicious Function Selectors

The bytecode exposes function selectors known to enable rugs (sweepETH, removeLiquidityNoFee, etc.).

Analyzer: Bytecode Patterns
Slug: suspicious_selectors

What it means

Even when the source code is unverified, the contract's public interface can be reconstructed from its function selectors. RektRadar tracks 17 selectors associated with rug operations: arbitrary token sweeps, fee bypass, liquidity manipulation.

Why it matters

A scammer who hides the source code can't hide the function selectors. The interface always leaks. If the contract exposes `sweepETH(uint256)`, the operator has a one-click rug button.

How RektRadar detects it

Walk the bytecode dispatch table, extract every 4-byte selector, intersect with the known-bad list.
