# Code Licensing

Tydro, a fork of the Aave Protocol operates on decentralized blockchain networks, with smart contracts that are self-executing and publicly auditable. These smart contracts and peripheral interfaces are licensed to define and regulate the use of the underlying code. The code exists across multiple GitHub repositories, and below are examples of some key licenses that apply to different Aave components:

* **Aave v3.3 Smart Contracts**: Business Source License 1.1 permits non-commercial use and modification, restricting competitive use for four years, with a transition to the MIT License on March 6, 2027​. ([GitHub](https://github.com/aave-dao/aave-v3-origin/blob/main/LICENSE))
* **Aave v3.2 Smart Contracts**: Business Source License 1.1 permits non-commercial use and modification, restricting competitive use for four years, with a transition to the MIT License on March 6, 2027​. ([GitHub](https://github.com/aave-dao/aave-v3-origin/blob/main/LICENSE))
* **GHO Stablecoin**: MIT License grants free and unrestricted rights to use, copy, modify, and distribute the software, provided the original copyright notice and license are included. The software is provided "as is," with no warranties or liabilities for any issues arising from its use. ([GitHub](https://github.com/aave/gho-core/blob/main/LICENSE))
* **Aave v2 Smart Contracts**: GNU Affero General Public License ([GitHub](https://github.com/aave/protocol-v2/blob/master/LICENSE.md))

## 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/resources/code-licensing.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.
