By integrating Zero-Knowledge Proofs (ZKPs) with Transport Layer Security (TLS), ExpandZK ensures that sensitive data can be authenticated without exposure, bridging Web2 and Web3 seamlessly. It empowers AI agents and decentralized applications (dApps) with privacy-preserving data verification, supporting use cases like decentralized finance (DeFi), digital identity, and beyond. ### Key Features * **Privacy-Preserving:** Uses ZKPs to validate data integrity without revealing sensitive information. * **Secure Bridging:** Facilitates reliable data verification between Web2 and Web3 environments. * **AI-Ready:** Designed to provide trustless authentication for AI agents in decentralized systems. Join our community to contribute to the future of secure, decentralized data verification for AI and Web3 applications. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.expandzk.com/welcome-to-expand.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
