> ## 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".

# Localnet

> Run a private Hedera network on your own machine with Solo for local development and CI, with the same components you find on mainnet and testnet.

## Introduction

A Hedera localnet gives you a network you fully control. Running outside the public networks removes network I/O bottlenecks and shared resource conflicts, and lets you configure the network however your tests need it. The recommended path is:

1. **Solo** *(recommended)*: Start local development and CI workflows on Solo, a Kubernetes-native network that fully mimics a production Hedera environment.
2. **Previewnet**: Test against Hedera Previewnet for early exposure to upcoming code changes.
3. **Testnet**: Validate against the stable test network before deploying to Hedera Mainnet.

## Solo

Solo is a Kubernetes-native tool for spinning up a private Hedera network that fully mirrors a production environment. It is the recommended local development environment for new projects and the migration target for teams moving off Hiero Local Node, which is deprecated and no longer supported.

### What Solo runs

A Solo deployment includes the same stack you find on Hedera mainnet and testnet:

* [**Consensus node**](/support/glossary#consensus): processes transactions and participates in Hashgraph consensus
* [**Mirror node**](/support/glossary#mirror-nodes): stores transaction history and serves REST, gRPC, and Web3 APIs
* [**Block node**](/support/glossary#block-node): streams record files from the consensus node and makes them available to downstream consumers
* [**JSON-RPC relay**](/support/glossary#json-rpc-relay): translates Ethereum JSON-RPC into Hedera transactions, enabling EVM tooling (MetaMask, Hardhat, Foundry, Ethers.js)
* [**Mirror Node Explorer**](/support/glossary#network-explorer): web-based block explorer for auditing transactions and accounts locally

### Default endpoints

On Solo 0.63 and later, `solo one-shot single deploy` exposes:

| Service | Endpoint |
| - | - |
| Consensus node gRPC | `localhost:35211` (node account ID `0.0.3`) |
| Mirror node REST API | `http://localhost:38081` |
| JSON-RPC relay | `http://localhost:37546` (chain ID `298`) |
| Mirror Node Explorer | `http://localhost:38080` |

These are defaults, not guarantees. Solo forwards to the next free port when one is taken, and the assignments changed in 0.63. Confirm what your deployment exposes with `solo deployment config ports --deployment <deployment-name>`.
