An introductory Dapp to connect the blockchain to your HTML web application. It covers the essential functions of reading blockchain data and interacting with transactions sent and received. In summary:
⦁ Switch between Mainnet and Testnet. These are separate blockchains, and many of the popular blockchains feature this separate test network for you to test it without sending real funds.
⦁ Displays live blockchain data. Market price, gas fees, latest block numbers etc.
⦁ Query an address. Search a wallet address to find its recent transactions and the amount sent. Much more data can be retrieved through the API.
⦁ Query a transaction. Search a specific transaction to get details about it such as amount sent and transaction fees. Much more data can be retrieved through the API.
⦁ Receive a payment. This checks all crypto received to a specific address, so you can validate if payments are received.
⦁ 3rd party transaction validation. All the query results create a URL to a blockchain scanner such as 'Etherscan' to validate and see more data.
Choose a directory on your computer to put the project files. The dapp uses an API to access blockchain data and transactions, so you'll need to create a key and add it to your script. Open up the API company listed in 'resources' below, and a create a free account. When you get the API key, open the file variables.php. Update the variables called $api_key with your key. Sometimes you need a separate key for test net and main net.
Create a wallet:
To fully test out the application, you'll need to create blockchain transactions, so you'll need a wallet. Try the wallet recommended in the 'resources' section below. In variables.php if you replace the $payment_receive_address variables with you address, you can test sending funds to yourself to see that work.
Loading the project:
You'll need to serve the website to your browser.
⦁ Open 'Command Prompt' on Windows.
⦁ Access the folder project folder by using the 'CD' command and the file path. If your folder was located in C:\Coding Projects\dapps, then the command would be cd Coding Projects\dapps
⦁ Serve onto localhost 8000: php -S 127.0.0.1:8000
⦁ Paste 127.0.0.1:8000 URL into the browser and it will load.
⦁ Software for coding. I use Visual Studio, but any IDE you prefer is ok. 'NotePad ++" is also good.
⦁ Faucet: faucet.rinkeby.io
⦁ Wallet: metamask.io
⦁ Scanner: etherscan.io

If you’ve just started a new business, or are planning on launching a new website for your existing business, you might be wondering how to find the best website template for your needs. There are so many options when it comes to choosing the right design for your company and brand that it can be pretty overwhelming. However, with the right preparation and research, you can create an eye-catching and effective website that drives visitors to take action. The first step in this process is finding the perfect template for your business. If you’re looking for some ideas about where to start with this process, read on for our list of helpful tips about how to select the best website template for your business.
The first thing you should look for when shopping for a new website template is whether or not it uses an easy framework like Bootstrap. If the design of your template is based on Bootstrap, you’ll be able to swap out the design with a different one – even if you hire a different developer. This is huge for two reasons: 1) It saves you money on long-term maintenance costs, and 2) It saves you time in the long run by making it easier to swap out designs. If the design of your website template is based on a framework like Bootstrap, you’ll be able to easily swap out the design with a different one in the future.
Before you even start looking at different website templates, you need to do your research. First, you’ll want to make sure you understand the different types of website templates that are available. There are basically three types of website templates online: 1) Templates built on premade design platforms, 2) Custom designs created by designers, and 3) Website builders like Wix. What’s important to note about these options is that premade design platforms are usually very simple and are designed for people who are very new to website design. They’re usually pretty limited in terms of functionality and flexibility. On the other hand, custom designed websites are the complete opposite – they offer a ton of flexibility and functionality, but can be expensive.
Another thing to do before you start shopping for a new website template is to check the templates for security. You can do this by looking at the loading source code in the website template and seeing if it references any security issues. You can also check the website URL and see if it’s currently listed on any blacklists. If it is, you’ll need to find another template to use. Security is a big deal when it comes to website design and functionality, especially if your company sells products or services online. Having a safe and secure website is paramount in terms of protecting your customers’ information and data. Remember, it’s not just your customers that you need to be thinking about – it’s also the search engines. A secure site will help your SEO efforts and make it easier for people to find your business online.
Once you’ve checked the templates for security, it’s time to start thinking about functionality. You want to look for a website template that has all the features your business needs. If you’re launching a new eCommerce website, for example, you’ll want to make sure to find a website design that has eCommerce functionality built-in. You may also need to find a website template that allows you to create multiple pages or sections of your website – depending on the needs of your business. Make sure your chosen website template has the functionality you need before you start making any payments.
With all the research you’ve done up until this point, you should have a pretty good idea of which website templates work best for your business. Now, it’s time to narrow down your selection by asking the right questions. Here are some questions to ask yourself when shopping for a new website template: - What is the purpose of the website? - Who is the target audience? - What is the tone of the website? - What content will be featured on the website? - How often will the content be updated? - What functionality is needed? - What features are required? - What style of website is best for the business? The answers to these questions will help you narrow down your selection and find the perfect template for your needs.
As you’re making your final decision about which website template to use, there’s one more thing you should do. You want to make sure that you try the live demo and make sure it meets all your needs. Even if you’ve narrowed down your selection, make sure that you try a few different templates to make sure you don’t miss out on a better option. You don’t want to find out after you’ve already purchased the website template that it doesn’t meet your needs. Try the live demo to make sure the template you’ve chosen is the best for your business.
Finally, make sure you check out the loading time of the website templates you’re considering. Website loading speed is becoming increasingly important. It has been found that a one-second delay in website response can result in a 7% reduction in conversions and a loss of $8,100 per minute in revenue. The good news is that there are a few things you can do to make sure you find a template that has a fast loading time. Look for these things when you do your research: - The type of design used. - What framework it’s built on. - How many external links are used. - Whether or not it uses a CDN. - What hosting plan is used. These are all factors that affect the loading time of a website. The faster the loading time, the more likely it is that customers will stay and interact with the site.
Selecting the best website template for your business can seem like a daunting task. However, if you take the time to do your research, choose a design that meets your company’s needs, and ask the right questions, it can be a fairly easy process. You can also make the process even easier by considering these tips for finding the best website template for your business.
