The Problem

The drupal theme cache tag invalidation pattern is frequently misapplied in smart contract and dapp development, leading to vulnerabilities, gas inefficiencies, or logic errors. This guide shows the correct implementation and common pitfalls to avoid.

Quick Fix

Wrong

Works but direct cache class usage.

Uses cache tag invalidation service.
