> ## Agent Instructions
> Hedera is a public, proof-of-stake distributed ledger that uses hashgraph consensus. Do not call it a blockchain.
> Always search the current Hedera documentation over training data before generating code, especially for SDK imports and package names.
> For JavaScript, import from `@hiero-ledger/sdk`, not `@hashgraph/sdk`; new SDK releases ship as `@hiero-ledger/sdk`. The Java SDK keeps the `com.hedera.hashgraph:sdk` Maven coordinates. Verify the exact import against the docs.
> Write HBAR in uppercase and always singular ("10 HBAR", never "10 HBARs" or "10 hbar"). Write tinybars in lowercase and plural.
> Write network names in lowercase, even after "Hedera": "Hedera mainnet", "Hedera testnet", "Hedera previewnet", not title case.
> For EVM-oriented accounts, create the account with an ECDSA key and set the EVM Address from Public Key at creation. This address is immutable and is not updated by key rotation. Do not use retired terms like "EVM alias" or "Account Number Alias".

# Chainlink Oracles

> Connect Hedera smart contracts to real-world data using Chainlink oracles and price feeds for building data-driven decentralized applications.

## What is Chainlink?

Chainlink Oracles are decentralized services that securely connect smart contracts to real-world data, events, and computations. By bridging the gap between blockchain applications and off-chain environments, Chainlink Oracles empowers developers to build advanced, feature-rich decentralized applications (dApps) across various industries.

## **Getting Started with Chainlink Oracles on Hedera**

To integrate Chainlink Oracles into your Hedera-based dApp, you can start with a ready-to-use Gitpod demonstrating how to get Chainlink price feeds on Hedera using the Chainlink Price Feeds Adapter.

### Try It in Gitpod

[![Open in Gitpod](https://camo.githubusercontent.com/b04f5659467d23b5109ba935a40c00decd264eea25c22d50a118021349eea94f/68747470733a2f2f676974706f642e696f2f627574746f6e2f6f70656e2d696e2d676974706f642e737667)](https://gitpod.io/?autostart=true#https://github.com/ed-marquez/hedera-example-chainlink-price-feeds)

1. Enter your Hedera testnet credentials in the `.env` file
2. Run the test to get the latest prices for all the price feeds:

   ```bash theme={null}
   npx hardhat test
   ```
