Using 'xplad'

The following information explains the functions you can use from xplad, the command-line interface that connects to XPLA Chain and enables you to interact with the XPLA Chain. Every active validator and full node runs xplad and communicates with their node via xplad. In this relationship, xplad operates as both the client and the server. You can use xplad to interact with the XPLA Chain by uploading contracts, querying data, managing staking activities, working with governance proposals, and more. For more general information at the command line, run xplad --help. For more information about a specific xplad command, append the -h or --help flag after the command, such as xplad query --help.

Accessing a Node

To query the state and send transactions, you must connect to a node, which is the access point to the entire network of peer connections. You can either run your own full node or connect to someone else’s.

Running Your Own Full Node

Running your own full node is the most secure option, but it comes with relatively high resource requirements. For more information about the requirements to run your own full node and a tutorial for installing xplad, see installation. For a tutorial that explains how to connect to an existing XPLA Chain, see joining a network.

Connecting to a Remote Full Node

If you don’t want to run your own full node, you can connect to someone else’s full node. As you consider your options for operators, prioritize operators you trust because malicious operators might intentionally return incorrect query results or censor your transactions. However, they will never be able to steal your funds because your private keys are stored locally on your computer or on your Ledger hardware device. Possible options of full-node operators include validators, wallet providers or exchanges.

To connect to the full-node, you need an address in the https://<host>:<port> format, for example This address has to be communicated by the full-node operator you choose to trust. You will use this address in the following section.

If you are not running a node yet would like to communicate through xplad, lists of public nodes can be found here.

Configuring xplad

xplad enables you to interact with the node that runs on the XPLA Chain, whether you run it yourself or not. To configure xplad, edit the the config.toml file in the ~/.xpla/config/ directory.

Querying Blockchain State

To query all relevant information from the blockchain, such as like account balances, amount of bonded tokens, outstanding rewards, and so on, use xplad query. The following list shows some of the most useful commands for delegators:

# query account balances and other account-related information
xplad query account <ACCOUNT_ADDRESS>
# Account address is of the form xpla1rEXAMPLE9tEXAMPLEf9cvEXAMPLEss
# you can find the one for your node by running `xplad keys list`

# query the list of validators
xplad query staking validators

# query the information of a validator given their address
xplad query staking validator <validatorAddress>

# query all delegations made from a delegator given their address
# (note: delegator addresses are regular account addresses)
xplad query staking delegations <delegatorAddress>

# query a specific delegation made from a delegator to a validator
xplad query staking delegation <delegatorAddress> <validatorAddress>

# query the rewards of a delegator given a delegator address (e.g. xpla10snjt8dmpr5my0h76xj48ty80uzwhraqalu4eg)
xplad query distr rewards <delegatorAddress>

Sending Transactions

To interact with the blockchain by sending transactions containing module messages with state-changing directives that get processed and included in blocks, use xplad tx. All of transaction-sending operations follow the form:

xplad tx ...

To learn more about the different types of interactions you can issue, see the section for each module.

Simulating a Transaction

To simulate a transaction without actually broadcasting it, append the --dry-run flag to the command statement:

xplad tx bank send \
    <sender_address> \
    <recipient_address> \
    <amount_and_denomination> \
    --chain-id=<chain-id> \
Example: simulate a XPLA transfer
xplad tx bank send \
    xpla1ru2ySENDER-EXAMPLEtf9cva9kp33h0jnsm9ss \
    xpla1rRECIPIENT-EXAMPLEtf9cva9kp33h0jnsm9ss \
    1axpla \
    --chain-id=cube_47-5 \

Generating a Transaction without Sending

To build a transaction and print its JSON format to STDOUT, append --generate-only to the list of the command line arguments. This allows you to separate the creation and signing of a transaction with the broadcasting.

xplad tx bank send \
    <sender_address> \
    <recipient_address> \
    <amount_and_denomination> \
    --chain-id=<chain-id> \
    --generate-only > unsignedSendTx.json
xplad tx sign \
    --chain-id=<chain_id> \
    --from=<address> \
    unsignedSendTx.json > signedSendTx.json
Example: sign an unsigned transaction
xplad tx sign \
    --chain-id=cube_47-5 \
    --from=xpla1EXAMPLEy09tEXAMPLEtf9EXAMPLE3h0EXAMPLEss unsignedTx.json

A healthy response should look similar to the following:

  "body": {
    "messages": [
        "@type": "/",
        "from_address": "xpla1ru2ySENDER-EXAMPLEtf9cva9kp33h0jnsm9ss",
        "to_address": "xpla1rRECIPIENT-EXAMPLEtf9cva9kp33h0jnsm9ss",
        "amount": [
            "denom": "axpla",
            "amount": "1"
    "memo": "",
    "timeout_height": "0",
    "extension_options": [],
    "non_critical_extension_options": []
  "auth_info": {
    "signer_infos": [
        "public_key": {
          "@type": "/cosmos.crypto.secp256k1.PubKey",
          "key": "A3Z50zDpCEXAMPLEG5Ru+DGOFEXAMPLEm0EXAMPLEKtxd"
        "mode_info": {
          "single": {
            "mode": "SIGN_MODE_DIRECT"
        "sequence": "0"
    "fee": {
      "amount": [],
      "gas_limit": "200000",
      "payer": "",
      "granter": ""
  "signatures": [

You can validate the transaction’s signatures by typing the following:

xplad tx sign --validate-signatures signedSendTx.json

You can broadcast the signed transaction to a node by providing the JSON file to the following command:

xplad tx broadcast --node=<node> signedSendTx.json


Transactions on the XPLA Chain need to include a transaction fee in order to be processed. This fee pays for the gas required to run the transaction. The formula is the following:

\[fees = gas * gasPrices\]

The gas is dependent on the transaction. Different transaction require different amount of gas. The gas amount for a transaction is calculated as it is being processed, but there is a way to estimate it beforehand by using the auto value for the gas flag. Of course, this only gives an estimate. You can adjust this estimate with the flag --gas-adjustment (default 1.0) if you want to be sure you provide enough gas for the transaction.

The gasPrice is the price of each unit of gas. Each validator sets a min-gas-price value, and will only include transactions that have a gasPrice greater than their min-gas-price.

The transaction fees are the product of gas and gasPrice. As a user, you have to input 2 out of 3. The higher the gasPrice/fees, the higher the chance that your transaction will get included in a block.

Setting Fees

Each transaction may either supply fees or gas prices, but not both. Most users will typically provide fees as this is the final cost you will end up incurring for the transaction being included in the ledger, whereas gas prices will be dynamically calculated depending on the validator.

Validators specify a minimum gas price that they use to determine whether to include a transaction, which they calculate during CheckTx, where gasPrices >= minGasPrices. Note, your transaction must supply fees that are greater than or equal to any of the denominations the validator requires.

Validators may start to prioritize transactions by gasPrice in the mempool, so providing higher fees or gas prices will likely yield higher priority of inclusion in a block.

To directly use fees:

xplad tx send ... --fees=100000axpla

If you use fees, validators will calculate the implied minGasPrices by dividing your fee with the estimated gas consumption, to properly assign the right priority to your transaction.

To use gas prices:

xplad tx send ... --gas-prices=0.05axpla

Automatic Fee Estimation

You may want to cap the maximum gas that can be consumed by the transaction via the --gas flag. If you pass --gas=auto, the gas will be automatically estimated before executing the transaction.

Gas estimate might be inaccurate as state changes could occur in between the end of the simulation and the actual execution of a transaction, thus an adjustment is applied on top of the original estimate in order to ensure the transaction is broadcasted successfully.

The adjustment can be controlled via the --gas-adjustment flag, whose default value is 1.0.

To get a direct fee estimation from xplad:

xplad tx estimate-fee ...\

To create and send transactions using fee-estimation, use the template below as a format:

xplad tx send ... \

Shell Autocompletion

Auto-completion scripts for popular UNIX shell interpreters such as bash and zsh can be generated through the completion command, which is available for both xplad and xplad. This allows for a more convenient way to interact with the XPLA Chain core endpoints when using the command-line.

If you want to generate bash completion scripts run the following command:

xplad completion > xplad_completion
xplad completion > xplad_completion

If you want to generate zsh completion scripts run the following command:

xplad completion --zsh > xplad_completion
xplad completion --zsh > xplad_completion

On most UNIX systems, such scripts may be loaded in .bashrc or .bash_profile to enable Bash autocompletion.

echo '. xplad_completion' >> ~/.bashrc
echo '. xplad_completion' >> ~/.bashrc

Refer to the user’s manual of your interpreter provided by your operating system for information on how to enable shell autocompletion.
