Web3 Developer Pitfalls: Data Leakage Incidents

Many developers are enthusiastic about using Vibe Coding to build tools and optimize development workflows — and it’s indeed very appealing. But once the application is deployed to the public network, risks immediately arise.

Two common fatal mistakes:

First, exposing user personal data. This not only damages user trust but can also trigger legal troubles.

Second, mishandling payment data. Storing data directly, transmitting in plaintext, poor permission management — any of these issues can escalate into a security disaster.

The worst-case scenario? Your application could be blacklisted for security vulnerabilities. Imagine projects exposed due to data leaks — public backlash, user loss, regulatory risks… none can be avoided.

Therefore, it is recommended: conduct security audits before going live, ensure sensitive data is encrypted during storage and transmission, and regularly check access logs. These are not optional but mandatory.
