More CLI commands


To get transaction information run the following:

starknet get_transaction --id=TRANSACTION_ID

The output should look like:

    "block_id": 1,
    "block_number": 1,
    "status": "PENDING",
    "transaction": {
        "calldata": [
        "contract_address": "0x039564c4f6d9f45a963a6dc8cf32737f0d51a08e446304626173fd838bd70e1c",
        "entry_point_selector": "0x362398bec32bc0ebb411203221a35a0301193a96f317ebe5e40be9f60d15320",
        "entry_point_type": "EXTERNAL",
        "type": "INVOKE_FUNCTION"
    "transaction_id": 1,
    "transaction_index": 0

The result contains:

  • transaction_id – The ID of the transaction, out of all sent transactions.

  • status – The status of the transaction. For a detailed list of supported transaction statuses, refer to the tx_status usage example.

  • transaction – The transaction data.

It may also include each of the following optional fields (according to the transaction’s status):

  • block_id – The ID of the block containing the transaction.

  • block_number – The sequence number of the block containing the transaction.

  • transaction_index – The index of the transaction within the block containing it.

  • transaction_failure_reason – The reason for the transaction failure.


Once the deploy transaction is accepted on-chain, you will be able to see the code of the contract you have just deployed. The output consists of a list of bytecodes, rather than the source code. That is because the StarkNet network gets the contract after compilation.

To get the contract at a specific address, run the following command:

starknet get_code --contract_address CONTRACT_ADDRESS

The output should look like:

    "abi": [
            "inputs": [
                    "name": "amount",
                    "type": "felt"
            "name": "increase_balance",
            "outputs": [],
            "type": "function"




Instead of querying a specific contract or transaction, you may want to query an entire block and examine the transactions contained within it. To do this, run the following:

starknet get_block --id BLOCK_ID

The output should look like:

    "block_id": 0,
    "previous_block_id": -1,
    "sequence_number": 0,
    "state_root": "069513ec3fe63e082c841ce3545a1059c54a513295fbd256ba04453953b94a4a",
    "status": "PENDING",
    "timestamp": 105,
    "transaction_receipts": {},
    "transactions": {
        "0": {
            "contract_address": "0x039564c4f6d9f45a963a6dc8cf32737f0d51a08e446304626173fd838bd70e1c",
            "type": "DEPLOY"

The result contains:

  • block_id – The block ID, a unique identifier of the block.

  • previous_block_id – the block ID of the previous block.

  • sequence_number – The sequence number of the block, which is the number of blocks prior to this block.

  • state_root – The root of a Merkle tree representing the StarkNet’s state after the given block.

  • status – The status of the block (for example, PENDING, which means that the block was created but has not been accepted on-chain yet).

  • timestamp – A timestamp representing the time this block was created.

  • transaction_receipts – Information about the transaction status and the corresponding L1<->L2 interaction, for every transaction included in the block.

  • transactions – A mapping of the transactions included in the block, according to their transaction IDs. Note that these are the same IDs used in the transaction_receipts mapping.

To query the last block, simply remove the --id argument.


Other than querying the contract’s code, you may also want to query the contract’s storage at a specific key. To do so, you first need to understand which key is of interest to you. As you saw before, StarkNet introduces a new primitive, which is storage variables. Each storage variable is mapped to a storage key (a field element). To compute this key, run the following python code:

from starkware.starknet.public.abi import get_storage_var_address

balance_key = get_storage_var_address('balance')
print(f'Balance key: {balance_key}')

You should get:

Balance key: 916907772491729262376534102982219947830828984996257231353398618781993312401

Now, you can query the balance using:

starknet get_storage_at \
    --contract_address CONTRACT_ADDRESS \
    --key 916907772491729262376534102982219947830828984996257231353398618781993312401

Using the same contract we have used so far, you should get:


Note that this is the same result obtained by the call to get_balance.

Later on, at the user authentication section, you will see a generalization of storage variables, which allow, for example, a balance variable for each user. This will require minor adjustments to the code above, which we will review in the relevant section.

Block-specific queries

Some of the aforementioned CLI functions have an additional argument, --block_id, which applies the given query to a specific block. For example, you may want to query the balance variable at some specific point in time.

To find out whether a CLI function can be executed as a block-specific query, simply use the --help argument to see if --block_id is part of the optional arguments for that function. In case you do not use the --block_id argument, the query will be applied to the last block.
