# System Architecture HodlFi's architecture is designed to be trust‑minimized and secure across both the Bitcoin and Ethereum (or other EVM) networks. It is organized in two layers: a contract layer that defines cross‑chain agreements, and a component layer that defines the roles of participants and off‑chain agents. This section highlights the structure, roles, and security boundaries, leaving time‑sequence details to the Loan Lifecycle. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.on.nexus/hodifi/core-system-specifications/system-architecture.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
