HyperPaxeer CLI

evmosd is the all-in-one command-line interface (CLI). It allows you to run an HyperPaxeer node, manage wallets and interact with the HyperPaxeer network through queries and transactions. This introduction will explain how to install the evmosd binary onto your system and guide you through some simple examples how to use evmosd.

​
Prerequisites

​
Go

HyperPaxeer is built using Go version 1.20+. Check your version with: 
go version
Once you have installed the right version, confirm that your GOPATH is correctly configured by running the following command and adding it to your shell startup script: 
export PATH=$PATH:$(go env GOPATH)/bin

​
jq

HyperPaxeer scripts are using jq version 1.6+. Check your version with: 
jq --version

​
Installation

You can download the latest binaries from the repo and install them, or you can build and install the evmosd binaries from source or using Docker.

​
Download the binaries

  • Go to the releases section of the repository
  • Choose the desired release or pre-release you want to install on your machine
  • Select and download from the Assets dropdown the corresponding tar or zip file for your OS
  • Extract the files. The evmosd binaries is located in the bin directory of the extrated files
  • Add the evmosd binaries to your path, e.g. you can move it to $(go env GOPATH)/bin
After installation is done, check that the evmosd binaries have been successfully installed: 
evmosd version

​
Build From Source

Clone and build the HyperPaxeer from source using git. The <tag> refers to a release tag on Github. Check the latest HyperPaxeer version on the releases section of the repository: 
git clone https://github.com/Paxeer-Network/Paxeer-Network.git
cd HyperPaxeer
git fetch
git checkout <tag>
make install
After installation is done, check that the evmosd binaries have been successfully installed: 
evmosd version
:::info If the evmosd: command not found error message is returned, confirm that you have configured Go correctly. :::

​
Docker

When it comes to using Docker with HyperPaxeer, there are two options available: Build a binary of the HyperPaxeer daemon inside a dockerized build environment or build a Docker image, that can be used to spin up individual containers running the HyperPaxeer binary. For information on how to achieve this, proceed to the dedicated page on working with Docker.

​
Run an HyperPaxeer node

To become familiar with HyperPaxeer, you can run a local blockchain node that produces blocks and exposes EVM and Cosmos endpoints. This allows you to deploy and interact with smart contracts locally or test core protocol functionality. Run the local node by executing the local_node.sh script in the base directory of the repository: 
./local_node.sh
The script stores the node configuration including the local default endpoints under ~/.tmp-evmosd/config/config.toml. If you have previously run the script, the script allows you to overwrite the existing configuration and start a new local node. Once your node is running you will see it validating and producing blocks in your local HyperPaxeer blockchain: 
12:59PM INF executed block height=1 module=state num_invalid_txs=0 num_valid_txs=0 server=node
# ...
1:00PM INF indexed block exents height=7 module=txindex server=node
For more information on how to customize a local node, head over to the Single Node page.

​
Using evmosd

After installing the evmosd binary, you can run commands using: 
evmosd [command]
There is also a -h, --help command available 
evmosd -h
It is possible to maintain multiple node configurations at the same time. To specify a configuration use the --home flag. In the following examples we will be using the default config for a local node, located at ~/.tmp-evmosd.

​
Manage wallets

You can manage your wallets using the evmosd binary to store private keys and sign transactions over CLI. To view all keys use: 
evmosd keys list \
--home ~/.tmp-evmosd \
--keyring-backend test

# Example Output:
# - address: HyperPaxeer19xnmslvl0pcmydu4m52h2gf0std5ee5pfgpyuf
#   name: dev0
#   pubkey: '{"@type":"/hyperpaxeer.crypto.v1.ethsecp256k1.PubKey","key":"AzKouyoUL0UUS1qRUZdqyVsTPkCAFWwxx3+BTOw36nKp"}'
#   type: local
You can generate a new key/mnemonic with a $NAME with: 
evmosd keys add [name] \
--home ~/.tmp-evmosd \
--keyring-backend test
To export your HyperPaxeer key as an Ethereum private key (for use with Metamask for example): 
evmosd keys unsafe-export-eth-key [name] \
--home ~/.tmp-evmosd \
--keyring-backend test
For more about the available key commands, use the --help flag 
evmosd keys -h

​
Interact with a Network

You can use evmosd to query information or submit transactions on the blockchain. Queries and transactions are requests that you send to an HyperPaxeer node through the Tendermint RPC. :::tip 👉 To use the CLI, you will need to provide a Tendermint RPC address for the --node flag. Look for a publicly available addresses for testnet and mainnet in the Networks page. :::

​
Set Network Config

In the local setup the node is set to tcp://localhost:26657. You can view your node configuration with: 
evmosd config \
--home ~/.tmp-evmosd
# Example Output
# {
# 	"chain-id": "hyperpax_125-1",
# 	"keyring-backend": "test",
# 	"output": "text",
# 	"node": "tcp://localhost:26657",
# 	"broadcast-mode": "sync"
# }
You can set your node configuration to send requests to a different network by changing the endpoint with: 
evmosd config node [tendermint-rpc-endpoint] \
--home ~/.tmp-evmosd

​
Queries

You can query information on the blockchain using evmosd query (short evmosd q). To view the account balances by its address stored in the bank module, use: 
evmosd q bank balances [adress] \
--home ~/.tmp-evmosd
# # Example Output:
# balances:
# - amount: "99999000000000000000002500"
#   denom: ahpx
To view other available query commands, use: 
# for all Queries
evmosd q

# for querying commands in the bank module
evmosd q bank

​
Transactions

You can submit transactions to the network using evmosd tx. This creates, signs and broadcasts a tx in one command. To send tokens from an account in the keyring to another address with the bank module, use: 
evmosd tx bank send [from_key_or_address] [to_address] [amount] \
--home ~/.tmp-evmosd \
--fees 50000000000ahpx \
-b block

# Example Output:
# ...
# txhash: 7BA2618295B789CC24BB13E654D9187CDD264F61FC446EB756EAC07AF3E7C40A
To view other available transaction commands, use: 
# for all transaction commands
evmosd tx

# for Bank transaction subcommands
evmosd tx bank
