hiero-cli
Use when user wants to interact with Hedera blockchain: create/transfer tokens, manage NFTs, deploy contracts, manage topics, transfer HBAR, sign x402 payment challenges, configure networks. ALSO use when an HTTP request returns 402 with a PAYMENT-REQUIRED header for the Hedera x402 scheme (or the user wants to pay an x402-gated endpoint on Hedera): read references/x402.md for the full GET→402→sign→retry flow. Provides full spec for hcli CLI tool. Trigger keywords: hedera, hiero, hbar, token, nft, contract, topic, x402, 402, payment-required, hcli, ledger

Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/hedera-dev/hedera-skills --skill hiero-cli- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads hiero-cli automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

hiero-cli (hcli)
hcli is a command-line tool for interacting with the Hedera blockchain — managing accounts, tokens (FT/NFT), smart contracts, consensus topics, and network configuration.
Binary syntax
hcli <plugin> <command> [options]
Global flags
| Flag | Short | Default | Description |
|---|---|---|---|
--format | -F | human | Output format: human or json |
--network | -N | active | Override active network for this command |
--payer | -P | operator | Override payer account for this command; defaults to operator if omitted |
--confirm | -Y | false | Skip all confirmation prompts |
--max-transaction-fee | -M | config | Max transaction fee ceiling for this run: HBAR (e.g. 20) or tinybars (200000000t). Overrides the default_max_transaction_fee config; 0 means no override |
Prerequisites
Before executing blockchain commands:
- Configure network:
hcli network use --global testnet - Set operator:
hcli network set-operator --operator <accountId>:<privateKey>
Key formats
Keys and signers accept multiple formats:
{accountId}:{privateKey}— inline pair, e.g.0.0.123:abc123...{ed25519|ecdsa}:private:{hex}— raw private key with type prefix{ed25519|ecdsa}:public:{hex}— raw public key (for supply/submit keys)kr_xxx— key reference stored in KMS- account alias — name registered in local state
Local state storage
State is persisted in ~/.hiero-cli/state/ as JSON files, one per plugin namespace:
| Plugin | File |
|---|---|
account | account-accounts-storage.json |
token | token-tokens-storage.json |
topic | topic-topics-storage.json |
batch | batch-batches-storage.json |
swap | swap-storage.json |
contract | contract-contracts-storage.json |
schedule | schedule-transactions-storage.json |
network | network-config-storage.json |
config | config-storage.json |
plugin-management | plugin-management-storage.json |
credentials (KMS) | kms-credentials-storage.json, kms-secrets-encrypted-storage.json |
Amount notation
"1"= 1 display unit (e.g. 1 HBAR, or 1 token with decimals applied)"100t"= 100 base/raw units (tinybars for HBAR, smallest token unit)

Agent instruction
Before executing any command, read references/<plugin>.md for the full command spec, all options, and examples.
Example: to use hcli token create-ft, first read references/token.md.
When working with batch commands, read both references/batch.md AND the reference for the plugin being batched.
Example: to batch hcli token mint-ft, read both references/batch.md and references/token.md.
When working with scheduled transactions, read references/schedule.md AND the reference for the command being scheduled.
Only commands marked [scheduled] in their reference support --scheduled <name> / -X.
Example: to schedule hcli token burn-ft, read both references/schedule.md and references/token.md.
x402 paid endpoints
If fetching a URL returns HTTP 402 with a PAYMENT-REQUIRED header, the
endpoint is x402-gated. Inspect the header payload: if its accepts lists a
hedera:mainnet / hedera:testnet exact requirement, read
references/x402.md and follow the flow there. The agent makes the HTTP
requests itself; hcli x402 sign only produces the PAYMENT-SIGNATURE value.
If the challenge is for a non-Hedera scheme, this CLI cannot sign it.
hcli not found / not installed
If any hcli command fails with a "command not found" or similar error, tell the user:
hcliis not installed or not available in PATH. Docs & quick start: https://www.npmjs.com/package/@hiero-ledger/hiero-cli#quick-startInstall with:
npm install -g @hiero-ledger/hiero-cliWould you like me to run the install command for you?
Do not run the install automatically — wait for the user's confirmation.
Operator not configured
If a command fails with CLI operator is not configured or similar:
- Inform the user the operator must be set before running any blockchain command
- Guide them:
hcli network set-operator --operator <accountId>:<privateKey> - Retry the original command after operator is set
Disabled plugin recovery
If a command fails with Plugin 'X' is disabled.:
- Inform the user that the plugin is disabled
- Offer to enable it:
hcli plugin-management enable --name X - Retry the original command after enabling
