# Fraud protection

As privacy-preserving technologies grow more powerful, so does the responsibility to ensure they’re not exploited by malicious actors. **Shielder**—a zero-knowledge solution for private transactions—has been designed not only to offer user confidentiality, but also to discourage abuse proactively.

The protocol integrates key mechanisms that strike a balance between privacy and accountability. These include:

* **Auditable architecture** (while preserving user anonymity)
* **Optional compliance features** for institutional or regulated use cases
* Strategic safeguards that make it harder for bad actors to exploit the system without compromising honest users
