> ## 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".

# Quickstart

> Run repeatable, non-interactive Hiero CLI scripts for Hedera workflows like creating accounts, transferring HBAR, and submitting topic messages, safe for CI.

## Scripting with Hiero CLI

Hiero CLI scripts let you run repeatable, end-to-end workflows for Hedera: creating accounts, transferring HBAR, creating tokens, submitting topic messages, and more. These scripts are designed to be non-interactive (safe for CI).

Example scripts live in the [Hiero CLI repository](https://github.com/hiero-ledger/hiero-cli/tree/main/examples/scripts):

* [`create-account-demo.sh`](https://github.com/hiero-ledger/hiero-cli/blob/main/examples/scripts/create-account-demo.sh) — operator setup, create account, view account
* [`transfer-hbar-demo.sh`](https://github.com/hiero-ledger/hiero-cli/blob/main/examples/scripts/transfer-hbar-demo.sh) — two accounts and an HBAR transfer
* [`token-topic-operations-demo.sh`](https://github.com/hiero-ledger/hiero-cli/blob/main/examples/scripts/token-topic-operations-demo.sh) — token and topic operations

Shared helpers: [`examples/scripts/common/`](https://github.com/hiero-ledger/hiero-cli/tree/main/examples/scripts/common) (`helpers.sh`, `setup.sh`). See the folder’s [README](https://github.com/hiero-ledger/hiero-cli/blob/main/examples/scripts/README.md) for how to run the demos.

## Prerequisites

* Node.js installation: 18.0.0 or higher
* Local mode (default): clone [hiero-cli](https://github.com/hiero-ledger/hiero-cli), then in the project root run `npm install` and `npm run build` so `dist/hiero-cli.js` exists
* Global mode (optional): install the CLI with `npm install -g @hiero-ledger/hiero-cli` and set `HIERO_SCRIPT_CLI_MODE=global` when running a script (see below)
* Operator credentials: `HEDERA_OPERATOR_ACCOUNT_ID` and `HEDERA_OPERATOR_KEY`. Copy [`examples/scripts/.env.sample`](https://github.com/hiero-ledger/hiero-cli/blob/main/examples/scripts/.env.sample) to `examples/scripts/.env` and fill in your values, or export both variables in your shell

<Tip>
  These are required for scripts that submit transactions to Hedera (e.g., create account, transfer, token operations).
</Tip>

## Script structure (recommended pattern)

All example scripts follow the same layout:

### Step 1: Strict bash mode

```bash theme={null}
#!/usr/bin/env bash
set -euo pipefail
```

* `-e` exit immediately on error
* `-u` error on undefined variables
* `-o` pipefail fail if any command in a pipe fails

### Step 2: Paths, helpers, and setup

Resolve the script directory and repository root, then source `common/helpers.sh` and `common/setup.sh`:

* **`helpers.sh`** — defines `run_hcli` (local vs global CLI), `print_step`, `print_info`, `print_warn`, `sleep_loop`, and `pick_random_name`
* **`setup.sh`** — loads optional `examples/scripts/.env`, runs dependency/build checks in local mode, and validates required operator env vars

### Step 3: `run_hcli` (where automation begins)

From `helpers.sh`, commands go through `run_hcli` instead of calling `hcli` or `node dist/hiero-cli.js` directly:

```sh theme={null}
export HIERO_SCRIPT_CLI_MODE="${HIERO_SCRIPT_CLI_MODE:-local}"

run_hcli() {
  if [[ "${HIERO_SCRIPT_CLI_MODE}" == "global" ]]; then
    hcli --format json "$@"
  else
    (cd "${PROJECT_DIR}" && node dist/hiero-cli.js --format json "$@")
  fi
}
```

Why this matters:

* Ensures every invocation uses `--format json` so scripts parse output reliably
* Local: runs the built CLI from `PROJECT_DIR`
* Global: runs the `hcli` on your `PATH` (after `npm install -g @hiero-ledger/hiero-cli`)

Set `HIERO_SCRIPT_CLI_MODE=global` when invoking a script if you do not want to build from source. The default is `local`.

## Quickstart: create an account and view it

The canonical example is `create-account-demo.sh`. From the `hiero-cli` repository root (with `HEDERA_OPERATOR_*` set or `.env` configured):

```sh theme={null}
./examples/scripts/create-account-demo.sh
```

With a globally installed CLI:

```sh theme={null}
HIERO_SCRIPT_CLI_MODE=global ./examples/scripts/create-account-demo.sh
```

The script configures testnet, sets the operator, creates one account with `1.0` HBAR, waits briefly for mirror indexing, then runs `account view`.

<Note>
  #### `network use` in the example scripts

  When `HIERO_SCRIPT_CLI_MODE=global`, the demos call `network use --network testnet`. When using the default local build, they call `network use --global testnet`. Keep the same branch as the script you are running. If a command fails or the help text differs, use `hcli network use --help` for the CLI you actually execute.
</Note>

Below is the same sequence as in `create-account-demo.sh` (paths, `run_hcli`, operator setup, create + view). For a maintained, executable copy, use that file in the repo; this block is for reading the pattern:

```sh theme={null}
#!/usr/bin/env bash
set -euo pipefail

SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
PROJECT_DIR="$(cd "${SCRIPT_DIR}/../.." && pwd)"

source "$SCRIPT_DIR/common/helpers.sh"
source "$SCRIPT_DIR/common/setup.sh"

print_step "Selecting Hedera testnet as the active network"
if [[ "${HIERO_SCRIPT_CLI_MODE}" == "global" ]]; then
  run_hcli network use --network testnet
else
  run_hcli network use --global testnet
fi

print_step "Configuring CLI operator for testnet"
run_hcli network set-operator \
  --operator "${HEDERA_OPERATOR_ACCOUNT_ID}:${HEDERA_OPERATOR_KEY}" \
  --network testnet

ACCOUNT_NAME="$(pick_random_name)"
print_step "Creating demo account: ${ACCOUNT_NAME} (1 HBAR)"
run_hcli account create --name "${ACCOUNT_NAME}" --balance 1.0

print_info "Waiting for mirror node (sleep_loop 5)..."
sleep_loop 5

print_step "Viewing account ${ACCOUNT_NAME}"
run_hcli account view --account "${ACCOUNT_NAME}"

print_step "Done."
```
