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

Prerequisites

Before executing blockchain commands:

1. Configure network: hcli network use --global testnet
2. 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:

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)

Plugin catalog

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.

hcli not found / not installed

If any hcli command fails with a "command not found" or similar error, tell the user:

hcli is not installed or not available in PATH. Docs & quick start: https://www.npmjs.com/package/@hiero-ledger/hiero-cli#quick-start

Install with:

npm install -g @hiero-ledger/hiero-cli

Would 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:

1. Inform the user the operator must be set before running any blockchain command
2. Guide them: hcli network set-operator --operator <accountId>:<privateKey>
3. Retry the original command after operator is set

Disabled plugin recovery

If a command fails with Plugin 'X' is disabled.:

1. Inform the user that the plugin is disabled
2. Offer to enable it: hcli plugin-management enable --name X
3. Retry the original command after enabling

Common workflows

Setup (first time)

hcli network use --global testnet
hcli network set-operator --operator 0.0.12345:302e...privatekey...

Create fungible token and transfer

# 1. Create token
hcli token create-ft --token-name "MyToken" --symbol MTK --decimals 2 --initial-supply 1000000

# 2. Associate recipient account
hcli token associate --token MTK --account 0.0.67890:302e...key...

# 3. Transfer tokens
hcli token transfer-ft --token MTK --to 0.0.67890 --amount 100

Deploy ERC-20 contract and interact

# 1. Deploy built-in ERC-20 template
hcli contract create --name myErc20 --default erc20 --constructor-parameter "MyToken" --constructor-parameter "MTK"

# 2. Check balance
hcli contract-erc20 balance-of --contract myErc20 --account 0.0.12345

# 3. Transfer via contract
hcli contract-erc20 transfer --contract myErc20 --to 0.0.67890 --value 50

Batch multiple token mints

# 1. Create batch
hcli batch create --name mintBatch --key 0.0.12345:302e...key...

# 2. Add transactions to batch (using --batch flag on batchify-compatible commands)
hcli token mint-ft --token MTK --amount 1000 --supply-key 0.0.12345:302e...key... --batch mintBatch

# 3. Execute batch
hcli batch execute --name mintBatch
