We are participates in the 0G project, where we focus on providing secure and stable node deployment and maintenance. Our role involves ensuring that nodes are correctly set up and continuously monitored to maintain optimal performance. By implementing rigorous security measures, we help safeguard the network against potential threats and vulnerabilities, contributing to the project's overall stability and resilience

In the Bool project, we are handles node validation and security audits. We conduct comprehensive assessments to identify and mitigate potential risks, ensuring the network's integrity. Our team also works on optimizing node performance, enabling Bool to operate efficiently and securely. Through our proactive approach to security and maintenance, we aim to support Bool's goals of creating a reliable and scalable decentralized network.
