> ## 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".

# Mainnet

> Join Hedera Mainnet

## Overview

The Hedera mainnet (short for main network) is where applications are run in production, with transaction fees paid in [HBAR](https://www.hedera.com/hbar). Any application or retail user can submit transactions to the Hedera mainnet; they're automatically consensus-timestamped and fairly ordered.

Any Hedera account can query data associated with Hedera's services and stored on-chain. Every transaction requires payment of a fee. Fees follow a [base fee + extras model](/learn/core-concepts/fee-model) defined in the network's fee schedule (system file `0.0.113`). Fees are denominated in USD (as tinycents) and paid in HBAR at the current exchange rate (100,000,000 tℏ = 1 ℏ). You can learn more about transaction fees [here](/learn/core-concepts/fee-model) and estimate your application costs using the [fee tables](/networks/fees) or the `POST /api/v1/network/fees` [Mirror Node endpoint](/reference/rest-api/network).

If you're looking to test your application (or just experiment), please visit [Testnet Access](/networks/testnet/access). The Hedera testnet enables developers to prototype and test applications in a simulated mainnet environment that uses test *HBAR* for paying transaction fees.

<Warning>
  **Transaction Throttles**
  Transactions on the Hedera Mainnet are currently throttled. You will receive a `"BUSY"` response if the number of transactions submitted to the network exceeds the threshold value.
</Warning>

### High-Volume Throttles

In addition to the standard throttles above, the network provides dedicated
**high-volume throttle capacity** for entity creation transactions that set
`high_volume = true`. These throttles run in parallel — they do not consume
capacity from the standard system, and the standard system does not consume
capacity from them.

| **Throttle Bucket** | **Transaction Types** | **Capacity** |
| - | - | - |
| HighVolumeCryptoThrottles | `CryptoCreate`, `ScheduleCreate` | *Set by governance* |
| HighVolumeTotalThrottles | All 14 [supported types](/learn/core-concepts/high-volume-entity-creation#supported-transaction-types) combined | *Set by governance* |

A high-volume transaction must pass **both** its per-type bucket and the total
bucket to be accepted. If either is exhausted, the transaction receives a `BUSY`
response — the same behavior as the standard throttle system.

<Note>
  High-volume transactions use **variable-rate pricing** that scales with utilization.
  See the [High-Volume Entity Creation](/learn/core-concepts/high-volume-entity-creation)
  guide to understand how this affects your transaction fees before opting in.
