Warning signal

Block-Dependent Logic

Behavior changes past a block number or timestamp comparison.

Analyzer: Source-Code Analysis
Slug: block_dependent_logic

What it means

The source gates logic on block.number or block.timestamp comparisons. Anything from honest launch phases to delayed traps: fees, limits or transfers that flip at a predetermined point.

Why it matters

Delayed traps are designed to outlive launch scanners: every check passes today, the trap arms next week. Block comparisons in token logic deserve manual reading.

How RektRadar detects it

Source regex on block.number/timestamp comparisons, raised as warning.
