## Oracles Implementation

### Gas Wallets

Gas wallets are used to push data to oracle contracts. To ensure uninterrupted oracle operation, Cooper Labs is maintaining sufficient gas in them. Anyone can monitor the wallets below to ensure they remain adequately funded at all times.

### Oracles Configuration

Settings that dictate how the oracle computes and updates data.

## How the Oracle Works

The market-based oracle aggregates trades from decentralized exchanges across multiple chains (Base, Sonic, etc.) using the VWAPIR methodology over a 1-hour window. Price updates are triggered when market prices deviate by 0.5% or every 12 hours as configured [here](#oracles-configuration).

{% hint style="info" %}
The sUSDp/USD value can also be retrieved using the chainlink-compatible adapter [smart contract](#assets-data) for sUSDp/USD.

# 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.parallel.best/developers-hub/parallel-v3/onchain-tools/oracles/dia/market.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.
