# What we do

Chainlink offers its own services for selected blockchains. At the same time, the speed at which new chains are deployed is constantly increasing. Be it as L2s or even L3s or as another competitive L1s.

Relink Protocol has developed a proxy service solution that forwards the random data request to an officially from Chainlink supported chain and processes the result accordingly.

A Relink oracle network signs the data generated by Chainlink and passes the original data along with the signatures to the callback method. The signature checks in the consumer base contract mean that no data can be changed on the way from the relaying backend.

## Process diagram 

The following is an example of the process flow for a Relink data request for Chainlink data on Polygon. For more information and details on the individual steps, please have a look at the [**Architecture Overview**](/architecture/overview.md).

## Real world example

As an example, a randomness request (VRF) on the EVM chain "Horizen EON" is used here.

* `InitiateRandomnessRequest`  in this [transaction](https://eon-explorer.horizenlabs.io/tx/0xca36b05a3e13347b2f9e3fe36ddba35d0ee269ad10ced83bcbe36425d6ace1ca) on Horizen EON (September-06-2023 10:40:43 PM +2 UTC)
  * it's an Example Consumer contract

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.relink.services/overview/what-we-do.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.
