### Existing Work

We have made substantial progress in the development and implementation of our security solutions. Below is the evidence of our existing work, including prototypes, research, and previous projects:

**1. Circuit Breaker SDK:**
- **Description:** The Circuit Breaker SDK is a comprehensive toolkit designed to provide real-time security features for DeFi protocols. It includes utilities for monitoring critical parameters, such as Total Value Locked (TVL), and implementing automated protective measures like transaction blocking and protocol pausing.

**2. Security Dashboard:**
- **Description:** Our Security Dashboard offers a user-friendly interface for monitoring the security status of DeFi protocols. It provides real-time insights into various metrics, helping protocol operators detect and respond to potential threats quickly.

**3. Fully Functional Proof of Concept (PoC):**
- **Description:** This PoC demonstrates the practical application of our on-chain firewall technology in a real-world scenario. It showcases how our security mechanisms can be integrated into a DeFi protocol to prevent unauthorized fund withdrawals and protect against hacks.

**Previous Work within OP/Superchain:**
- **Workshops and Educational Initiatives:** We have hosted multiple workshops and educational sessions focused on token security and the benefits of implementing on-chain firewalls. These events have helped raise awareness and drive the adoption of our solutions within the OP community.
- **Collaboration with the OP Ecosystem:** Active participation in the Optimism community has allowed us to collaborate with other developers and projects, contributing to the overall security and resilience of the ecosystem.

Our existing work demonstrates our commitment to enhancing the security of DeFi protocols through innovative, real-time solutions. By building on these foundations, we aim to continue our progress and make a significant impact on the Optimism and broader Superchain ecosystems.
