Frequently asked questions regarding the Bitcoin and Altcoin Wallets WordPress plugin.
Which coins are currently available?
The list of wallets that you can connect to directly is constantly growing.
To check what’s currently available go to https://www.dashed-slug.net and check the menu under Wallets → Coin Adapter Extensions and see the available RPC adapters.
Is it secure?
The Bitcoin and Altcoin Wallets plugin is only as secure as your WordPress installation. Regardless of whether you choose to install this plugin, you should have already taken steps to secure your WordPress installation. At a minimum you should do the following:
- Install a security plugin such as Wordfence.
- Read the Codex resources on Hardening WordPress.
- If you are connecting to an RPC API on a different machine than that of your WordPress server over an untrusted network, make sure to tunnel your connection via
stunnel. See here.
Do I really need to run a full node? bitcoind is too resource-hungry for my server.
Running a full node requires you to set up the daemon on a VPS or other machine that you own and administer. Normally the full blockchain needs to be downloaded, so you need to make sure that your server can handle the disk and network requirements.
Instead, you can choose to install one of the available coin adapters that are backed by cloud wallet services. These currently are:
Study the services and their terms of service including what fees they charge before choosing to use them.
From version 1.1.0 onward, this plugin is compatible with the bittiraha-walletd wallet. From the project’s description on GitHub:
Lightweight Bitcoin RPC compatible HD wallet This project is meant as a drop-in replacement for bitcoind for use in lightweight servers.
This is a wallet based on
bitcoinj and does not store the blockchain locally. You will have to install this on a VPS or other server via the shell.
A downside is that the
walletnotify mechanism and the
listtransactions command are not implemented. This means that there is no easy way for the plugin to be notified of deposits. Deposits will not be recorded in the transactions table. Users will not be emailed when they perform deposits and they will not be able to see their deposits in the
[wallets_transactions] UI. Deposits will correctly affect users’ balances. You have been warned.
Can you install/configure the plugin for me? / I am having trouble with the bitcoin.conf file
I am available to answer any specific questions if you attempt to install the plugin and you face some problem. Unfortunately I do not undertake installation and configuration of the plugin.
Keep in mind that no software is set-and-forget. Once you install software, it then needs to be maintained. If you find that you are having trouble installing the plugin or connecting it to a wallet, even with help, this is a good indication that you should not be running a wallet with people’s money on it.
Remember that you have two options: stand-alone wallets or web wallets. Running a web wallet is considerably easier than a stand-alone wallet, as it does not require system administration skills. As a general rule, if you have trouble using Linux from the command line, you will be better off installing a web wallet.
I cannot connect to a wallet running on my home computer
Unless your home internet connection has a static IP and you have opened the correct ports on your router/firewall you will not be able to use your home computer as a wallet backend. In fact, this is not a very good idea. Ideally you need a dedicated server to run a wallet with the availability required by a site that serves multiple users. Virtual private servers (VPSs) should be OK as the wallets do not max-out CPU usage under normal operation, after the blockchain finishes syncing. Shared/managed hosting plans are not appropriate for running wallet daemons. If you have a shared/managed hosting plan (i.e. no ssh access), you are stuck with using web wallets.
Check with your hosting plan for disk space and memory requirements against the requirements of the wallet you wish to run. For Bitcoin core, click here.
How can I integrate the plugin with my site?
Just insert the shortcodes anywhere to create forms to let a logged in user:
- deposit funds:
- withdraw funds:
- transfer funds to other users:
- view their balance:
- view past transactions:
These shortcodes render knockout.js-enabled forms. Read the shortcodes documentation for more details.
You can enter the same UI elements into your theme’s widget area. Simply go to Appearance → Widgets and use the provided front-end widgets.
You can also use a special menu item to display the user balances as part of a nav menu:
- Go to Appearance → Menus.
- At the top right side of the screen, click Screen Options.
- Under Boxes, make sure that Bitcoin and Altcoin Wallets balances is selected.
- Now you are free to enter the balances menu item into your menus.
I don’t like the built-in forms. Can I provide my own?
First of all, the forms can be styled with CSS. They have convenient HTML classes that you can use.
If you wish to create forms with completely different markup, you can provide your own views for these shortcodes. Use the
wallets_views_dir filter to override the directory where the views are stored (the default is
wallets/includes/views). Most people will not need to do this.
Read the shortcodes documentation for more details.
The provided built-in forms talk to a JSON API that is available to logged in users. If you choose to build your own front-end UI, you can do your AJAX calls directly to the JSON API.
Refer to the JSON API documentation for details.
I want to do transactions from the PHP code of my theme or plugin.
You can use the PHP API directly.
Refer to the PHP API documentation for details.
Can you add XYZ coin for me?
Yes and no. I have received a large amount of requests from small coins and cannot cater for them all at the moment. I do try to implement some of the requests I receive.
If your coin’s wallet has a standard RPC API that is a direct fork of Bitcoin core, then you should be able to modify the Litecoin adapter to suite your needs. Feel free to republish it after modifying the code. There are some instructions on how to do this here.
If your coin is an ERC-20 token then there is no support for that at the moment. Ideally this is something that will be implemented in the future.
Are you available for custom development work?
Unfortunately I do not undertake custom projects. If you have an idea about a cool extension then please let me know about it. If it is a good fit for the project, it will be added to the backlog. When implemented, It will be available either to all users for free, or for dashed-slug premium members.
Can you add fiat currency deposits?
I do not have plans to add fiat currency deposits. That is not to say that someone cannot develop an extension to do this.
Can you build an exchange on top of the plugin?
Yes this is in the future plans.
I want to pay for premium membership but cannot or do not want to pay via PayPal.
I am curretly in the process of building a plugin extension that will allow you to pay for membership via cryptocurrencies. In the meantime, you may contact me directly at email@example.com if you wish to send a Bitcoin payment and I will activate your membership manually.
How can I get support or submit feedback?
Please use the support forum on WordPress.org for all issues and inquiries regarding the plugin.
