# Overview

### What is Tydro?

The Tydro App hosts lending markets, letting users lend assets to earn interest and borrow assets against posted collateral. The protocol is built on the Aave V3 codebase that has processed over $20B+ of loans and runs on the Ink network, an Ethereum Layer 2 blockchain with native exchange integrations and compliance layer.

Tydro V2 powers on chain SOFR, offering fixed-rate, floating-term overcollateralized loans.

* Borrowers lock in a set rate that does not change, with no maturity date, so the cost of holding a position stays predictable regardless of utilization or market swings. 
* Suppliers earn a floating yield that moves with the market.
* Borrowers post collateral against the assets they want to borrow.

At launch, Tydro V2 offers a fixed-rate secured loan facility against kBTC with instant liquidity for borrowers and lenders. As additional markets, allocators, and vaults go live, the collateral set will expand to include assets such as tokenized equities, gold, RWAs, and other assets held in qualified custody. Over time additional vault products, fixed-term lending facilities, fixed rate products, and more will be developed alongside Tydro's partners and surfaced on the app.tydro.com interface. Current and future security audits will be hosted on the [audit reports](/vi.-security/audit-reports.md) page. 

> **Important note**: [tydro.com](https://tydro.com) is the only official URL of the tydro app and documentation, always verify the [official URLs](/vii.-developers/developer-overview/official-links.md), protocol [contract addresses](/vii.-developers/developer-overview/smart-contracts.md) and {# website status page link } before interacting to mitigate potential phishing attempts. The team will never ask you to use another interface or ask for sensitive information such as private keys or personal information.

## 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, and the optional `goal` query parameter:

```
GET https://docs.tydro.com/i.-introduction/overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
