B07. Wallet | Using RPC Wallet

Qwertycoin RPC Wallet is a HTTP server which provides JSON 2.0 RPC interface for Qwertycoin payment operations and address management. Qwertycoin RPC Wallet allows you to accept incoming payments, generate an address for each user via Qwertycoin RPC Wallet JSON RPC API and much more. RPC Wallet API page contains detailed description of every method.

Download Qwertycoin RPC Wallet

To start integration process you should first download Qwertycoin RPC Wallet, you can find it here: https://qwertycoin.org/wallet/

You may also build RPC Wallet from source code: https://github.com/qwertycoin-org/qwertycoin

Generate a new wallet

To start using RPC wallet you must first generate a container. Container file is the only file that stores all data required to run your service. It contains user addresses and private keys required to operate them. Make sure to backup this file regularly.

To generate a new container you should run the following command:

 $ ./walletd --container-file=<mycontainer> --container-password=<mypass> --generate-container

where:

• <mycontainer></mycontainer> is the container file name and a path to it (relative or absolute); path is optional in this argument, specifying only a container's name will result in new file located in the same folder as RPC Wallet
• <mypass></mypass> is a secret password for the new wallet file. Whichever you like;
• --generate-container option tells RPC wallet to generate container file and exit.

Note: if <mycontainer></mycontainer> exists Qwertycoin RPC Wallet will show you the notification and will ask you to provide a different name.

If the operation was successful you will get a corresponding message with your new Qwertycoin address. At the same time Qwertycoin RPC Wallet will save your container on the local disk (in the same folder where Qwertycoin RPC Wallet is located) and shut down.

Start Qwertycoin RPC Wallet

There are two ways to start Qwertycoin RPC Wallet:

Start with a remote connection to the Daemon

Remote connection allows you to bind your Qwertycoin RPC Wallet to a remote Qwertycoin daemon (Qwertycoind). You may establish Qwertycoin daemon on both local and remote machines and connect to. Such type of connection allows you to start Qwertycoin RPC Wallet on a relatively slow machine while heavy loaded daemon is going to work on a separate powerful server.

• For local daemons use localhost or 127.0.0.1 as an IP address.
• For remote daemons specify the remote daemon's IP address.

Default Qwertycoin daemon ports are 8196 and 8197.

Use the following command to start Qwertycoin RPC Wallet with a remote connection:

 $ ./walletd --container-file=<mycontainer></mycontainer> --container-password=<mypass></mypass> --daemon-address=<remote_ip></remote_ip> --daemon-port=8197

Note: Qwertycoin daemon (Qwertycoind) should be running at the moment RPC wallet is starting in a remote connection mode.

Note: Qwertycoin RPC Wallet will still provide some functionality even if Daemon server fails. For example, you will be able to generate addresses for your users.

Start as in-process node

You can also start Qwertycoin RPC Wallet with an in-process node. This allows you to start RPC Wallet out-of-box with no external daemon required. You will get a fully functional node for Qwertycoin network inside Qwertycoin RPC Wallet. You don't have to download or install anything besides Qwertycoin RPC Wallet. This approach will help reduce the overheads required for infrastructure maintenance.

Use the following command to start Qwertycoin RPC Wallet with an in-process node

 $ ./walletd --container-file=<mycontainer></mycontainer> --container-password=<mypass></mypass> --local

Configure Qwertycoin RPC Wallet

To configure RPC wallet you can use both command line and config file. Config file allows you to configure your settings only once and use "--config" option further. The command below launches Qwertycoin RPC Wallet with a specific config file:

 $ ./walletd --config=/home/Downloads/myconfig.conf

To get help on available options run:

 $ ./walletd -h

Please note, Qwertycoin RPC Wallet config file may consist only of these options:

Option	Description	Config Example	Console Example
bind-address	Which address to bind Qwertycoin RPC Wallet to. Default value is 0.0.0.0	bind-address = 127.0.0.1	--bind-address=127.0.0.1
bind-port	Which port to bind Qwertycoin RPC Wallet to. Default value is 8070	bind-port = 8071	--bind-port=8071
daemon-address	Qwertycoin daemon (Qwertycoind) address for remote daemon connection infrastructure	daemon-address = 127.0.0.1	--daemon-address=127.0.0.1
daemon-port	Qwertycoin daemon (Qwertycoind) port for remote daemon connection infrastructure. Default Qwertycoin daemon ports are 8196 and 8197	daemon-port = 8197	--daemon-port=8197
container-file	Mandatory. Your container's file name	container-file = mycontainer	--container-file=mycontainer
container-password	Mandatory. Your container's password	container-password = mypassword	--container-password=mypassword
log-file	A name of log file that you want to use for logging. Default is walletd.log	log-file = mylog.log	--log-file=mylog.log
server-root	Working directory that you wish to use for Qwertycoin RPC Wallet. Default is current working directory.	server-root = /home/Downloads/RPCWallet	--server-root=/home/Downloads/RPCWallet
log-level	Level of logging. Default is 1.	log-level = 2	--log-level=2
testnet	Allows you to run Qwertycoin RPC Wallet in testnet.	testnet = no	--testnet=no
local	Option that allows you to start Qwertycoin RPC Wallet as an in-process node	local	--local

Here's an example of a config file:

 $ cat rpc_wallet.conf 
 container-file = mycontainer
 container-password = mypassword
 daemon-port = 8197
 bind-port = 8050
 testnet = no

You may specify Qwertycoin config directly through console arguments. Here's the same example as above in console:

 ./walletd --container-file=mycontainer --container-password=mypassword --daemon-port=8197 --bind-port=8050 --testnet=no

Note: config file's path is relative to current working directory, not server root.

Note: options "container-file" and "container-password" should ALWAYS be set (in either command line or config file mode).

Note: "container-file" and "log-file" options are relative to "server-root". "server-root" default is the current working directory.

Run Qwertycoin RPC Wallet

Qwertycoin RPC wallet can be started in both daemon and console modes.

• Daemon mode - Qwertycoin RPC Wallet is launched in the background, while you can continue to work with a console window.
• Console mode - Qwertycoin RPC Wallet is launched and prints log messages on the screen.

Qwertycoin RPC wallet starts in console mode by default.

Start as daemon (UNIX only)

To start RPC wallet as daemon just set "--daemon" (or short "-d") option.

 ./walletd --container-file=mycontainer --container-password=mypassword --daemon

Note: it's a common practice for daemons to set server root directory.

Server root is the directory where RPC Wallet stores all its files. All relative paths in RPC Wallet configuration are relative to the server root directory.

Start as service (Windows only)

To run RPC wallet as a service on Windows you have to do the following:

1. Create a config file and place it in the same directory as your RPC wallet's executable resides in.

A note for Windows Users: In case the server root in config file is not specified all paths should be ABSOLUTE. If you set server root you can use relative paths (relative to your server root);

2. Register your Qwertycoin RPC Wallet as a service. To do so, run the following command as an ADMINISTRATOR:

 walletd.exe --register-service

3. After you see message about successful service registration you can run it in your Services panel.

Uninstall service (Windows only)

If you want to delete RPC wallet you have to unregister windows service first (if you have registered it before). Run as an ADMINISTRATOR:

 walletd.exe --unregister-service

Greetings to Karbo Developer (We will edit this soon, but first we had needed a fast solution to support an Exchange during the implementation). This is the major reason for this copy n paste. Im sorry for that. I appreciate your work.
