Using the `provenanced` binary as a blockchain client. |
{% hint style="info" %} To get started with Provenance Blockchain you first need to install Provenance Blockchain and have access to a Provenance Blockchain node.
See Installing Provenance Blockchain if you have not installedprovenanced.
See Running a Node if you do not have access to a node or do not want to connect to a publicly available node. {% endhint %}

Flags:
-h, --help help for provenanced
--home string directory for config and data (default "/Users/mconroy/Library/Application Support/Provenance")
--log_format string The logging format (json|plain) (default "plain")
--log_level string The logging level (trace|debug|info|warn|error|fatal|panic) (default "info")
-t, --testnet Indicates this command should use the testnet configuration (default: false [mainnet])
--trace print out full stack trace on errors
Use "provenanced [command] --help" for more information about a command.
{% hint style="info" %} Commands used throughout these examples will use some consistent flags that are worth noting.
--testnet to use testnet rather than mainnet
--chain-id pio-testnet-1 assumes that we are connected to the Provenance Blockchain testnet
--node tcp://localhost:26657 this is the default node location and port. In the examples below, we'll connect to a remote node without starting a local node. The remote node is a public testnet node hosted at https://rpc.test.provenance.io:443.
{% endhint %}
The provenanced binary provides a command-line interface to create and query transactions. To create a transaction requires just a few items:
- a key pair capable of signing the transaction
- a key pair capable of paying the gas fee
- a blockchain node to submit the transaction to.
All interactions with Provenance Blockchain are secured with a public/private key pair that will act as your account(s) on the blockchain. We use the 44'/1'/0'/0/0 BIP32 path as an example where the coin-type "1" is a reference to Provenance Blockchain testnet. We use the 44'/505'/0'/0/0 BIP32 path as an example where coin-type "505" is a reference to the HASH token on Provenance Blockchain mainnet.
{% hint style="success" %} Refer to the Accounts section for more information HD Wallet paths. {% endhint %}
Create a key pair and store it in a local Keyring (change <name-of-key> to a string value of your choosing):
# TESTNET (note: --hd-path "44'/1'/0'/0/0" can be used instead of coin type)
provenanced keys add <name_of_key> --coin-type=1 --testnet -i
# MAINNET (note: the default coin type is 505 for mainnet so no extra parameters are required)
provenanced keys add <name_of_key> -i
**Important** write this mnemonic phrase in a safe place.
It is the only way to recover your account if you ever forget your password.

{% hint style="info" %} When generating a new key it is important to store the generated mnemonic in a safe location to be used in the event that the key needs to be restored. {% endhint %}
This command will prompt you for a mnemonic to restore the key at a specific path.
# TESTNET

Hash is the digital currency used to transact on the Provenance Blockchain. In order to execute any commands beyond basic queries against a node, you'll need Hash. On testnet receiving Hash is as easy as accessing the Provenance Blockchain Faucet and supplying your address. This small distribution of Hash on testnet allows you to develop against the public testnet as well as quickly get a feel for how the Provenance Blockchain ecosystem operates.
{% hint style="info" %}
The address associated to your key pair is a Bech32 address which is an encoded value of the public key portion of our key pair. Provenance Blockchain testnet Bech32 addresses begin with tp whereas mainnet addresses begin with pb.
Once we transferred Hash to our Bech32 address, it became a Provenance Blockchain account. {% endhint %}
First, find the Bech32 address of the key created in the previous section:
provenanced --testnet keys show <name-of-key>The output will show the address of your key:
- name: <name-of-key>
type: local
address: tp1cuknswnphchtkwe68t4nshcaj4l4azv9ml2qhs
pubkey: tppub1addwnpepqgxlsrgv9znqeass2al9u9h37khapuecpp0al82wqyhzvn9hwtnzwak5uf3
mnemonic: ""
threshold: 0
pubkeys: []Copy the key address and open the Provenance Blockchain testnet Hash faucet https://explorer.test.provenance.io/faucet, paste the value, and press Get Tokens:

Your address will now have enough Hash to pay gas fees. Confirm your key address has Hash:
provenanced --testnet q bank balances tp1cuknswnphchtkwe68t4nshcaj4l4azv9ml2qhs \

pagination:

total: "0"{% hint style="info" %}
The --node flag allows us to connect our provenanced client to a node running remotely. Thus, we're connecting to a public testnet node hosted at https://rpc.test.provenance.io:443.
{% endhint %}
Using a json parsing tool is often useful for formatting data returned from provenanced commands. One way to accomplish this is to use the jq command to parse and query json data. For more info on jq see https://stedolan.github.io/jq/download.
Example provenanced command that uses jq to parse the output.
