Modifiable Limits

Max-transaction / max-wallet limits can be changed by the owner after launch.

Analyzer: Source-Code Analysis
Slug: modifiable_limits

What it means

The source exposes setMaxTx, setMaxWallet, setMaxBuy or setMaxSell. These limits are legitimate anti-whale tooling, but a hostile operator can shrink them to dust to effectively freeze exits.

Why it matters

Setting maxSell to near zero is a soft honeypot that no static fee check catches: sells technically work, for amounts too small to matter.

How RektRadar detects it

Source regex on limit-setter signatures, raised as info severity - it needs other signals to become dangerous.
