Warning signal

Conditional Transfer

The transfer path branches on block.number, block.timestamp or tx.gasprice.

Analyzer: Source-Code Analysis
Slug: conditional_transfer

What it means

The _transfer implementation reads block or transaction context. Transfers behaving differently by block height, time or gas price is the toolkit of timed honeypots and anti-simulation tricks.

Why it matters

A token can sell fine during launch hour and brick afterwards, or behave correctly only under simulation-like gas prices. Static launch checks pass; buyers later cannot exit.

How RektRadar detects it

Source regex on _transfer bodies referencing block.number, block.timestamp or tx.gasprice. Sibling signals: block_dependent_logic, dynamic_fee_by_block.
