Desktop

 A desktop wallet is special software that is installed on a PC or laptop. There are two types of desktop wallets: “thick” (heavy) and “thin” (light). The former requires downloading the entire blockchain, which will later be stored on the computer, while taking up significant space on the hard disk. The light client accesses the blockchain through third-party services and therefore does not require downloading and storing it.

A cryptocurrency wallet is not exactly what we are used to evisioning when we think of a wallet. It’s completely different from a physical wallet or purse, of course.

Your crypto wallet is an encrypted address in the network that stores all of your transaction history and, consequently, the codes that allow you to make transactions. When you make a transaction, the rest of the network only can see the address and the amount of transfer. There are no references to personal data or location. Before starting crypto wallet development, it is worth clarifying the following issues:

  • What type of coin you are going to buy and store. It can be bitcoin, ethereum or a huge variety of altcoins, including stablecoins. Crypto wallet developers have created special wallets for each coin. But there are also multi-currency wallets for storing several different coins in one place.
  • How often you plan to access the wallet. If you want just to buy coins, deposit them and wait for a few months or even years until they increase in value, then you should pay your attention to specific models. But if you plan to actively trade, regularly deposit and withdraw assets from the wallet, then you will need to use other wallet types.
  • Anonymity. Not all wallets support Nakamoto’s ideas about anonymity and privacy. Many of them require passport data and a phone number. Then, you can deposit and withdraw from the bank cards. The other wallets don’t even require an email address, but support transactions only with cryptocurrencies, without fiat money.

Several steps in creating a crypto wallet

Defining the purpose. The customer designates his main goal, which depends on what he is doing: trading or investing, transferring or storing funds.

Work specification. It is necessary to conduct a marketing analysis and determine the initial data provided by the client.

Technology definition. Experienced professionals use only the latest technologies to create applications for Android and iOS. The customer should use only a quality product with useful functions.

Launching applications in test mode. This eliminates errors and malfunctions and helps to check the correct operation of the new application.
