Danger signal

Dynamic Fee By Block

Fees are computed from block.number or block.timestamp - taxes change on their own.

Analyzer: Source-Code Analysis
Slug: dynamic_fee_by_block

What it means

The source assigns fee variables from block context. The effective tax is a function of time: typically low at launch and confiscatory later, without any owner transaction to alert monitoring.

Why it matters

This is the honeypot that fires with no trigger to watch: nobody calls setFee, the fee just grows. Simulation at launch reads the friendly value.

How RektRadar detects it
