> ## 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".

# Oracle Networks

> Overview of oracle networks integrated with Hedera, including Pyth, Supra, and Chainlink, that bring off-chain data like market prices to smart contracts.

Oracle networks integrated with Hedera provide secure, reliable, and decentralized off-chain data feeds for applications and smart contracts. They bridge the gap between blockchain-based systems and external data, enabling smart contracts to access real-world information like market prices, weather forecasts, and more to execute automated actions, such as payments or trading decisions.

Hedera supports integration with multiple oracle networks, each offering unique features and specialized data feeds tailored to various use cases. Explore the oracle networks below to find the one that best suits your needs:
