> ## 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".

# Use of HBAR and tinybars

> This page outlines the correct usage of "HBAR" and "tinybars" in Hedera-related writing.

## HBAR

When referring to the Hedera native currency, use the singular form of the noun **HBAR**. For example:

* "I bought 10 **HBAR** yesterday"

Do not use the plural form of the noun, as this style rule applies even when referring to multiple units of **HBAR**.

## tinybars

When referring to fractions of **HBAR**, use the plural form **tinybars**. For example:

* "I will transfer 1,000 **tinybars** from my account to yours"

Do not use the singular form of the noun, as any reference should be plural since one **HBAR** equals 100,000 **tinybars**
