Send and receive Groestlcoins with Groestlcoin Core 25.0 graphical user interface

As a continuation of managing Groestlcoin wallet articles Send coins in Groestlcoin network from command line with Groestlcoin Core 25 in year 2023, Build and run the Groestlcoin Core 25.0 node with a graphical wallet and Generate a new Groestlcoin address (wallet) and list wallets and addresses using command line cli verson 25.0.0. This article will show how to transfer Groestlcoins with the official Groestlcoin Core desktop application and the look and feel of the wallet functionality of the Groestlcoin Core.

Overview balances

The basic topics to manage a Groestlcoin wallet with the official software (ALWAYS use only official software) are:

  • Groestlcoin Core provides two key functionalities – become a Groestlcoin node, i.e. a part of the Groestlcoin network and the Groestlcoin wallet with command line interface and graphical user interface.
  • Groestlcoin Core can generate and Groestlcoin address.
  • a Groestlcoin wallet contains Groestlcoin addresses.
  • the Groestlcoin Core has a wallet functionality application, but before using it the wallet needs to synchronize with the Groestlcoin network. So the Groestlcoin GUI application will start a Groeslcoin node and it will try synchronizing with the network.
  • Groestlcoin Core includes groestlcoin-qt application, which offers the graphical user interface
  • Using groestlcoin-qt is really simple to manage wallets, generate Groestlcoin addresses, and get information for the local Groestlcoin node, which is used by the wallet application.

Here are the steps needed to transfer funds under the Linux distro of Ubuntu securely, but this time from the Gnome. To be able to transfer money securely without any 3rd party involved (no online wallet or wallets, which is unclear which node they connect to) just funds from your personal Groestlcoin wallet address on your computer to another Groestlcoin wallet address it is needed a running Groestlcoin node using Groestlcoin Core graphical user interface:groestlcoin-qt – this application provides basic graphical user interface for managing the Groestlcoin wallets. After the Groestlcoin Core is build and installed (check this article – Build and run the Groestlcoin Core 25.0 node with a graphical wallet), start the /[user_home_directory]/groestlcoin-core/bin/groestlcoin-qt. Apparently, the Groestlcoin site offers a compiled version of Groestlcoin Core (with an installer for Windows, too), but be careful what you download and from where! The best way is to just follow our article to build it yourself under Ubuntu.

SCREENSHOT 1) The loading screen at the start of groestlcoin-qt application.

It may take time to start because it is loading the local cached block index and if the node was fully synced lately, it may take a minute or two to load.

Send coins in Groestlcoin network from command line with Groestlcoin Core 25 in year 2023

This article an updated version of Send coins in Groestlcoin network with Groestlcoin Core (cli), because it appeared many things handling the wallets with the command-line have changed.

main menu
groestlcoin-cli sendtoaddress

The basic notes to send and receive are:

  • a Groestlcoin address is required.
  • a Groestlcoin wallet contains Groestlcoin address
  • the Groestlcoin wallet application (i.e. Groestlcoin node, it is the same application) needs a synchronized Groestlcoin to operate properly, such as send and receive Groestlcoin coins.
  • the Groestlcoin wallet may be created, loaded or imported with the Groestlcoin tools.
  • if there is only one Groestlcoin wallet loaded it would be the default one and it would not require additional options to the Groestlcoin tool to specify, which wallet would be used for the current command.

Here are the steps needed to transfer funds under the Linux distro of Ubuntu securely. To be able to transfer money securely without any 3rd party involved (no online wallet or wallets, which is unclear which node they connect to) just funds from your personal Groestlcoin wallet address on your computer to another Groestlcoin wallet address it is needed a running Groestlcoin node using Groestlcoin Core command line tool:groestlcoin-cli – this is command line tool for managing the Groestlcoin wallets.

STEP 1) Install and run a Groestlcoin node with groestlcoind

The first step is to start a Groestlcoin node by following this updated article – Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS. It will help the user to build from the official source code the Groestlcoin Core software, which will include the Groestlcoin node and wallet functionalities. All of the file paths and application names are real and correct if the above article was used.
It’s worth mentioning, that the Groestlcoin node must be running and synced with the Groestlcoin network. Here is how to check it:

myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli getblockchaininfo

Build and run the Groestlcoin Core 25.0 node with a graphical wallet

In continuation to the article Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS, which offers only a command line management to the Groestlcoin wallets, this article will show a more convenient way with a graphical user interface. Groistlcoin Core software includes a graphical user interface for the Groestlcoin wallet.

main menu
node window synced with network

The first thing is to build the Groestlcoin Core software as shown in the link above with some additional dependencies and options.
It’s worth noting there is a package for the graphical Groestlcoin wallet on the official site of Groestlcoin, but the idea behind this series of articles is to build everything from the official source code and to run an own Groestlcoin node, which will be used for the user’s Groestlcoin wallet. Such no trusting anyone or any site, but only the official source code of the project. The security is really important in the crypto world.

Here are the steps to build and run the Groestlcoin node with wallet functionality – command line and graphical user interface. The graphical user interface uses QT5 to build the wallet interface and all libraries are included in the official Ubuntu repositories.

STEP 1) Build and run the Groestlcoin node

For more detailed information check out Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS.

First, install the dependencies but with additional libraries including the QT5 and qrencode. Update the system and install the needed additional binaries and libraries to build and run the Groestlcoin core package. These dependencies include the ones needed to build the Groestcoin wallet functionality with GUI! By default, many Linux systems won’t even include dependencies needed to build the wallet.

sudo apt -y update
sudo apt -y upgrade
sudo apt install build-essential libssl-dev libboost-all-dev libtool automake libevent-dev bsdmainutils git make g++ gcc autoconf cpp ngrep iftop sysstat autotools-dev pkg-config libminiupnpc-dev libzmq3-dev libdb-dev libdb5.3++-dev sqlite3 libsqlite3-dev

Generate a new Groestlcoin address (wallet) and list wallets and addresses using command line cli verson 25.0.0

This article an updated version of Generate a new Groestlcoin address (wallet) and list accounts and addresses, because it appeared many things handling the wallets and address with the command-line have changed.

main menu
new wallet and address

The generation of a new Groestlcoin address is relatively simple, just use the command line tool – groestlcoin-cli, which is a Groestlcoin Core RPC client talking to the Groestlcoin node. So a working and synchronized Groestlcoin node is needed. Check out Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS for more information how to build and run a Groestlcoin node.

DO NOT TRUST any online website or any other Internet source to generate your Groestlcoin wallet address for you. DO IT YOURSELF with the official software from the official site!
If the user followed the above link to build and run a Groestlcoin and has waited to synchronize, it is time to use the groestlcoin-cli to create a wallet and then generate addresses. In fact, the wallet contains Groestlcoin addresses and it may be encrypted for better security. The Groestlcoin node is running and synchronized.

STEP 1) Create a new or load an old Groestlcoin wallet.

There is no default wallet and no wallet is loaded automatically on start, by default (indeed a wallet may be automatically loaded, but it should be specified on loading).
List all the Groestlcoin wallets under the current user:

myuser@mydesktop:~$ cd groestlcoin-core/bin/
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listwallets
[
]
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listwalletdir
{
  "wallets": [
  ]
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
error code: -18
error message:
No wallet is loaded. Load a wallet using loadwallet or create a new one with createwallet. (Note: A default wallet is no longer automatically created)

Apparently, there are no wallets, so here is how to create a wallet:
Create a wallet with:

myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli createwallet my-groestlcoin-wallet
{
  "name": "my-groestlcoin-wallet"
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli encryptwallet 'joo8laeW9Chietae&phu'
wallet encrypted; The keypool has been flushed and a new HD seed was generated (if you are using HD). You need to make a new backup.

When creating one wallet, it will become the default one, and all commands on groestlcoin-cli will use it. To specify exactly the name of the wallet with the command, the option “-rpcwallet=” should be used. In general, with one wallet there is no need to specify the wallet name, but when there are two or more loaded wallets, it is mandatory to specify with “-rpcwallet=” the wallet name.
Creating one more wallet with groestlcoin-cli will result in two loaded wallets, so after that, all commands should include “-rpcwallet=”.

myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli createwallet my-groestlcoin-wallet-2
{
  "name": "my-groestlcoin-wallet-2"
}
myuser@mydesktop:~/groestlcoin-core/bin$ ./groestlcoin-cli -rpcwallet="my-groestlcoin-wallet-2" encryptwallet "ief0ahshao8ca8Dai-ng"
wallet encrypted; The keypool has been flushed and a new HD seed was generated (if you are using HD). You need to make a new backup.

Building from source and run a Groestlcoin node (cli only) under Ubuntu 22.04 LTS

It was a bit while after the Building from source a Groestlcoin node (cli only) under Ubuntu 16 LTS. So after 6 years is it the same procedure or there are additional or simplified steps (to build) and run a cryptocurrency Groestlcoin node? The GRS price seems the same as it was 6 years ago, but there are some new things in the software.

main menu
groestlcoin-cli getblockchaininfo

The first step is to build the software and it is one of the most important steps – download the source code ONLY from the official source, check the official site https://www.groestlcoin.org/groestlcoin-core-wallet/ where the source code could be downloaded or to see where is the official place for the source code – https://github.com/Groestlcoin/groestlcoin. Check the links yourself! The https://github.com/Groestlcoin/groestlcoin git link will be used to download the latest stable version of the code and to build a Groestlcoin node, which may or may not include wallet capabilities. Building the Groestlcoin core package from the source you’ll have your private and secure Groestlcoin node (and wallet), which could be used to make secure transactions and receive funds in the Groestlcoin network and a lot more! DO IT YOURSELF – the most secure way of generating a Groestlcoin wallet address, making transactions such as sending and receiving coins, and storing your wallets.

STEP 1) Update your system and install dependencies

Update your system and install the needed additional binaries and libraries to build and run the Groestlcoin core package. These dependencies include the ones needed to build the Groestcoin wallet functionality! By default, many Linux systems won’t include dependencies needed to build the wallet.

main menu
sudo apt install groestlcoin dependencies

sudo apt -y update
sudo apt -y upgrade
sudo apt install build-essential libssl-dev libboost-all-dev libtool automake libevent-dev bsdmainutils git make g++ gcc autoconf cpp ngrep iftop sysstat autotools-dev pkg-config libminiupnpc-dev libzmq3-dev libdb-dev libdb5.3++-dev sqlite3 libsqlite3-dev

Send coins in Groestlcoin network with Groestlcoin Core (cli)

Here are the steps needed to make a secure transfer of your funds under linux distro of Ubuntu. To be able to transfer money securely without any 3rd party involved (no online wallet) just funds from your personal Groestlcoin wallet address on your computer to another Groestlcoin wallet address we need a running Groestlcoin node using Groestlcoin Core tool:

groestlcoin-cli

The cli tool for managing the Groestlcoin wallets.

STEP 1) Install and run an Groestlcoin node with groestlcoind

Here you can follow this tutorial – Running a Groestlcoin node (wallet cli) from source under Ubuntu 16 LTS.
The Groestlcoin node must be running and synced with the Groestlcoin network.

STEP 2) Check how many funds you have in your Groestlcoin wallet address

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaccounts
{
  "": 0.00000000,
  "myfunds": 527.36851543,
  "test": 0.00000000
}

So we have

myfunds account

with 527.36851543 Groestlcoin coins, an account could have multiple Groestlcoin addresses and a wallet could have multiple accounts (as you can see from the example above) , so we can check the amount of coins on each address associated with the account:

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
[
  [
    [
      "FabGnY2ovd3jnddgyjiltd456hdfjklFBs", 
      527.36851543, 
      "myfunds"
    ]
  ]
]

You can see there are 527.36851543 Groestlcoin coins in our account “myfunds” in the Groestlcoin wallet and the Groestlcoin address is FabGnY2ovd3jnddgyjiltd456hdfjklFBs

STEP 3) Unlock your wallet

The wallet is encrypted with a password, so before doing any transactions you must unlock the account for a given amount of time with:

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli walletpassphrase "my_wallet_pass" 300

So your wallet will stay unlocked for 300 seconds, this is the purpose of the third parameter.

STEP 4) Send the amount you like to the Groestlcoin wallet address you like

BE CAREFUL the operation is irreversible, if you put wrong address or unknown or unexciting one, you’ll lose your Groestlcoin coins!!
We want to send 2 coins to “FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe”

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli sendfrom "myfunds" "FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe" 2
3293d8f8acc2689ff54fe70a28da24cd313c324f1f335e80d22add08588d73d1

If you see the transaction ID, it means the you have executed the command successfully and you can check the status of the transaction.

STEP 5) Check the transaction status.

The status of your transaction could be checked in sites offering Groestlcoin block explorer sites like

https://groestlsight.groestlcoin.org/

Here is the screenshot of the status page:

main menu
Transaction details in https://groestlsight.groestlcoin.org/

You can see there are two addresses and a fee, which is just a “0.0000226GRS”, the transaction 2 GRS has (S), which means “Spent” and the 0.04326832 GRS (U), which means unspent, but it was needed to complete the transaction. So you spent 2.0000226 GRS to transfer 2.00 GRS.
And verify the other address has the coins:

srv@local:~/groestlcoin-core/bin$ 
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
[
  [
    [
      "FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe", 
      2.00000000, 
      "mytestwallet"
    ]
  ]
]

Here is the whole output of the “/groestlcoin-cli” tool:

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaccounts
{
  "": 0.00000000,
  "myfunds": 527.36851543,
  "test": 0.00000000
}
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli walletpassphrase "my_wallet_pass" 300
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli sendfrom "myfunds" "FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe" 2
3293d8f8acc2689ff54fe70a28da24cd313c324f1f335e80d22add08588d73d1
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaddressgroupings
[
  [
    [
      "FabGnY2ovd3jnddgyjiltd456hdfjklFBs", 
      525.32522451, 
      "myfunds"
    ], 
    [
      "Fjqkflgitg459tdfgjjkrthurDFGFhghhj", 
      0.04326832
    ]
  ]
]
srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli listaccounts
{
  "": 0.00000000,
  "myfunds": 525.36849283,
  "test": 0.00000000
}

Also you might want to delete your shell history because of the saved password phrase!

Troubleshooting

If you get

srv@local:~/groestlcoin-core/bin$ ./groestlcoin-cli sendfrom "myfunds" "FmjjtD2cejkrjeghrfhhaerGDFGdjfhffe" 2
error code: -13
error message:
Error: Please enter the wallet passphrase with walletpassphrase first.

You must unlock your account! If you did it but still the error persisted you probably have to increase the unlock time. Look STEP 2)
