Develop Bitcoin Wallet - Blog S-PRO

Technological progress goes further breaking frontiers between virtual and real worlds. Blockchain takes the lead in this process. Along with standard online payments, there are more and more use cases of cryptocurrency payment methods being integrated. Nowadays it is even possible not only to use a ready Bitcoin wallet but also create it by yourself.

Here we’ll get the knowledge on how to make your own bitcoin wallet application and integrate it into your online trading platform as means of payment for your products or services.

What are the reasons for making such apps

Bitcoin transactions are almost impossible to imagine without electronic wallets. They can operate with different electronic currencies or with just one of them like bitcoin itself.

Reasons for creating wallet app - S-pro blog

Bitcoin wallet application is a usual software wallet that can store, receive and transfer bitcoins making all the transactions safe for both parties. That’s just the main features that such wallets can provide. Additionally, they can store digital keys, etc.

Now let’s check what such apps can give to both sides of bitcoin transactions.

  • Fast and simple

With ordinary payment method, like banking transactions, it might be quite simple to perform an operation between different accounts of the same bank or between some banks in your region. But it will definitely take much more time when conducting financial transactions between international institutions. Even ten business days might not be enough.

Especially if it involves large sums of money like those more than $100 000. It takes too much bureaucracy and time. Aren’t you exhausted with it?

With blockchain-based solutions, it takes several hours maximum. So it makes carrying out financial operations with blockchain impressively useful regarding time.

  • Safe and secure

A unique signature signs all the transactions. Once a deal is initiated no components can be changed. That guarantees an entirely safe and reliable transaction from a sender to recipient.

  • Anonymous

Cryptocurrency transactions are known for their complete anonymity. You can use those systems without showing any previous credit history as it is usually required with banks. Also, no other personal information needs to be specified for performing transactions. Which builds an additional layer of security, as the standard poorly developed systems might be at risk.

To conduct electronic payments, all you need is a wallet address which is actually a long line of digits and numbers. With it, you can have all the information about the transaction, but you have zero data about a recipient or a sender depending on the type of your operation. So it is absolutely anonymous for both parties.

No risks of unauthorized access from the third party to the transaction data are provided by the combination of 2 digital keys (open and closed ones) that only recipient and sender of that particular transaction receive.

  • Independent from the economic situation

From time to time some economic collapses happen in different countries. They do influence the standard banking systems, and many investors tend to lose their deposits. Cryptocurrencies are not affected by those situations as they have decentralized support. This factor fully protects bitcoin owners from any political or economic crisis.

  • No inflation

With standard currencies, inflation often happens when some crisis comes. On the contrary, bitcoin will never be devalued due to the fact that the number of nominal currency units will never be more than a specified amount of 21 million mark.

What are the opportunities for using bitcoin?

Bitcoin benefits - S-pro blog

Bitcoin gives numerous opportunities for electronic payments. As it provides a possibility to bypass the state financial systems. Plus the primary focus for such apps is to make electronic payments as reliable as possible. Blockchain in a way supports these transactions making them unchangeable by fixating each stage of the trade in an encrypted form. So no third parties are engaged in the process.

As emphasized above, anonymity is another crucial factor where bitcoin payments become beneficial for customers. Famous trading platforms have already experienced all of the mentioned advantages of integrating such electronic payments. Among them are Zappos, WordPress, Amazon, etc.

Let’s sum it all up in a pure form:

  • Bypassing state financial system
  • Reliability of transactions
  • Immutability of records
  • No third parties
  • Complete anonymity
  • Example of famous users

Main points when developing such an app

Bitcoin has an open source code, no one owns it, and anyone can become a member of the network. So it’s not that hard to build a bitcoin wallet application as someone might imagine. There are plenty of libraries available free of charge that can help you to implement your idea.

Wallet app functionality - S-pro blog

First, let’s distinguish the possible functionality of such an app:

  • Registration/Authorization system

It is a mandatory and unconditional feature that provides a necessary level of security.

  • Profile

It has all the necessary personal information that can be used for overall payment transactions management.

  • QR code scanner

Participates in the process of sending and receiving money

  • Exchange rate

Shows the bitcoin price at the market and helps to exchange it for other currencies

  • Trade service

Gives an opportunity to be a seller or to see other sellers

  • Addresses generation

Generates new addresses for all transactions

  • Real-time payment tracking

At any time you can check the status of the payment stage

  • Push-notifications

All the essential notifications will come when some change is made like transaction receipt or bitcoin rate change, etc.

  • Security

The simplest form of security is setting a PIN code and password for app protection.

Of course, security is a much more complicated issue as the rest. So it should be considered with more accuracy. The first thing is to encrypt the wallet with a secure password. Additionally, you can create a backup of the wallet and store it in different protected places. Another popular approach is to use a multi-signature. Imagine, in order to send money you need to receive 2-3 signatures. By the way, all of them should be set from the beginning when creating an address.

Once you define the functionality, all you need is to find the optimal API for your wallet. And don’t forget about the software libraries that will be synchronized with your wallet.

That’s the perfect time to get to know the most popular libraries for creating your own bitcoin wallet app. By the way, besides those apps with the libraries according to their functionality, there are many applications can be designed that are related to cryptocurrencies.
