# Integrate Oracle Services

#### Supra

**Supra** (<https://supra.com>) is a novel, high-throughput Oracle & IntraLayer: A vertically integrated toolkit of cross-chain solutions (data oracles, asset bridges, automation network, and more) that interlink all blockchains, public (L1s and L2s) or private (enterprises).

Supra provides decentralized oracle price feeds that can be used for on-chain and off-chain use-cases such as spot and perpetual DEXes, lending protocols, and payments protocols. Supra’s oracle chain and consensus algorithm makes it the fastest-to-finality oracle provider, with layer-1 security guarantees. The pull oracle has a sub-second response time. Aside from speed and security, Supra’s rotating node architecture gathers data from 40+ data sources and applies a robust calculation methodology to get the most accurate value. The node provenance on the data dashboard also provides a fully transparent historical audit trail. Supra’s Distributed Oracle Agreement (DORA) paper was accepted into ICDCS 2023, the oldest distributed systems conference.

#### RedStone

**RedStone** (<https://redstone.finance/>) is an Oracle that delivers frequently updated, reliable, and diverse data feeds for your dApp and smart contracts on multiple L1s & L2s.

RedStone offers a radically different design of Oracles catering to the needs of modern DeFi protocols.

* Data providers can avoid the requirement of continuous on-chain data delivery
* Allow end users to self-deliver signed Oracle data on-chain
* Use the decentralized Streamr network to deliver signed oracle data to the end users
* Use token incentives to motivate data providers to maintain data integrity and uninterrupted service
* Leverage the Arweave blockchain as cheap and permanent storage for archiving Oracle data and maintaining data providers' accountability

## 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.bsquared.network/for-developers/oracle_service.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.
