# Overview This section covers the core functional concepts of Helios: **BTC-native lending markets, interest rate mechanics, supported assets**, and unique user features like **partial collateral swaps**. These are the building blocks of how users interact with Helios and how the system behaves. In summary, Helios’s core concepts center on **making Bitcoin a full-fledged participant in DeFi**: BTC holders can earn yield natively, borrowers can obtain liquidity without leaving Bitcoin, and everyone benefits from unique tools (like partial swaps) to optimize their financial strategies. All of this is delivered in a self-custodial, trust-minimized package that feels as simple as using a single-chain protocol on Ethereum, despite the underlying complexity of operating on Bitcoin. --- # 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.
