# Audits

> Smart Contract as well as Application safety and security is paramount to us. Therefore we regularly conduct On & Off-Chain audits with reputable auditors.

## Security Philosophy

Our top priority is to systematically mitigate and reduce potential risks through a multi-layered security approach:

* **In-Depth External Audits**
  * Collaborating with leading security researchers to identify potential vulnerabilities, logical edge-case errors, and structural inefficiencies
* **Continuous Monitoring**
  * Ongoing on-chain tracking and alerting framework deployments to watch over smart contract and application interactions post-launch

> 🔒 **Security Reporting:** Found a potential vulnerability? Please do not open a public issue. Reach out directly to our security team at [**<u>security@digitalasset.com</u>**](mailto:security@digitalasset.com).
