# ILBFactory

Required interface of LBFactory contract

## LBPairInformation

```solidity
struct LBPairInformation{
    uint16 binStep;
    ILBPair LBPair;
    bool createdByOwner;
    bool ignoredForRouting;
}
```

Structure to store the LBPair information, such as:

* binStep: The bin step of the LBPair
* LBPair: The address of the LBPair
* createdByOwner: Whether the pair was created by the owner of the factory
* ignoredForRouting: Whether the pair is ignored for routing or not. An ignored pair will not be explored during routes finding

# 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://developers.lfj.gg/contracts/interfaces/ilbfactory.md?ask=<question>
```

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.
