# Oracles

> Oracle providers for bringing external market data and offchain signals into Arc smart contracts.

Connect your Arc smart contracts to real-world data using the oracle providers
listed below. They offer price feeds and related infrastructure for DeFi,
trading, lending, and other financial applications.

If your application also needs to query historical onchain data, see
[Data indexers](/arc/tools/data-indexers).

## Providers

### [Chainlink](https://chain.link)

Decentralized oracle network for bringing market data and other offchain
information onchain. Chainlink Data Feeds aggregate multiple data sources and
publish secure, widely used feeds for lending, trading, stablecoins, and
tokenized assets.

* [**Data Feeds**](https://docs.chain.link/data-feeds): Access decentralized
  price feeds for smart contract integrations.
* [**Data Streams**](https://docs.chain.link/data-streams): Retrieve low-latency
  market data delivered through a pull-based model.
* [**Feed Explorer**](https://data.chain.link): Browse available feeds and
  contract addresses across supported networks.
* [**Contract Addresses**](https://docs.chain.link/data-feeds/price-feeds/addresses):
  Find deployed price feed contract addresses across supported networks.

### [Chronicle](https://chroniclelabs.org)

Onchain data infrastructure for high-integrity price feeds and tokenized asset
verification. Chronicle originated as the oracle for Sky (MakerDAO) and provides
DeFi price feeds alongside proof-of-asset attestations for lending, stablecoins,
tokenized treasuries, and other RWAs.

* [**DeFi Price Feeds**](https://chroniclelabs.org/dashboard/oracles): Access
  high-integrity feeds purpose-built for lending, stablecoins, and other onchain
  financial applications.
* [**Proof of Asset**](https://chroniclelabs.org/dashboard/proofofasset):
  Provide cryptographic attestations of reserves and collateral for tokenized
  treasuries, stablecoins, RWAs, and other assets where verifiable backing is
  essential.
* [**Docs**](https://docs.chroniclelabs.org/): Get started with Chronicle's
  oracle integration guides.

### [Pyth](https://www.pyth.network)

Real-time, first-party market data oracle for onchain applications. Pyth
provides price feeds across crypto, equities, FX, metals, and more, with pull
and push delivery models for different latency and cost requirements.

* [**Price Feeds**](https://docs.pyth.network/price-feeds): Integrate real-time
  price data into Arc smart contracts.
* [**EVM Contract Addresses**](https://docs.pyth.network/price-feeds/core/contract-addresses/evm):

### [RedStone](https://www.redstone.finance)

Modular oracle network for secure, real-time price feeds and specialized market
data. RedStone supports push, pull, and hybrid delivery models, with coverage
across crypto assets, LSTs, LRTs, RWAs, tokenized funds, FX, and other custom
data feeds for DeFi and institutional applications.

### [Stork](https://www.stork.network)

Ultra-low-latency oracle protocol for real-time market data. Stork provides
fast, pull-based delivery with cryptographic verifiability for DeFi applications
that require sub-second pricing.

* [**Docs**](https://docs.stork.network/): Get started with Stork's oracle
  integration guides.
