Corresponding to the rising demand for cryptocurrency, many brands have introduced their crypto wallets with advanced features. If you plan to build your crypto wallet, this article is for you. By reading the details given here, you will understand how to create a crypto wallet capable of thriving amid the highly competitive and rapidly growing crypto industry.

What is a Crypto Wallet?

A cryptocurrency wallet is a blockchain wallet that supports transactions in cryptos. While these types of wallets are similar to digital wallets designed to hold cash and cards, crypto wallets cannot directly store the currency of real-world value. These wallets manage cryptocurrency transactions using private and public keys, allowing users to and receive cryptocurrencies such as Eth, Bitcoin, Tether, and Binance.

Beyond all the controversies and misconceptions, cryptocurrency wallet app are easy to use as you merely need a wallet address and a public or private key. Wallet owners can share their public keys with the person they want so that they can send or receive money whenever required. The same is impossible with a private key since these details are like debit card details. No one wants to share their bank or debit card-related credentials to give people access to their bank accounts.

How Does a Crypto Wallet Work?

Crypto wallets are based on blockchain, using cryptography technology to enable high security and immutability. The basic mechanism of a blockchain wallet includes cryptography-based private and public keys that provide them with private and public keys. Let’s understand the role of these keys on a crypto wallet’s functioning:

1. Public Keys– Public keys are not the wallet address, but can be considered as the hashed version of the wallet address. Whenever someone has to send cryptocurrency to your wallet, they will use the public key (that you need to provide them) to encrypt the input into a respective output which is not public. Still, the same is associated with the public address of the receiver’s wallet.
2. Private Keys– Private keys are associated with the wallet address and the public key. Private keys are the only means by which you can decrypt the information of the crypto sender and unlock the relevant content. That’s how private keys enable you to access the wallet and complete the transactions. private key can be written in various types.

–256 character long binary code

–64 digit hexadecimal code

–QR code

–Mnemonic phrase

3. Initiate Transaction– Whenever you need to send crypto to any wallet, you will use the private key to sign the transaction before sending it to the decentralized blockchain network. In comparison, validators or the nodes in the blockchain network use the public key (associated with the private key) to validate the transactions transmitted on the blockchain’s decentralized ecosystem.
4. Encrypt Transaction– Those unaware of the crypto wallet mechanism will think that private keys can be copied or used repeatedly for transaction-related fraud and manipulation. However, each transaction done through a private key is unique and ensures hard-to-hack security in every transaction.
5. Authentication– Regarding the authentication of crypto recipients, they get authenticated when the sender assigns the transaction to the receiver’s public key and the public key is associated with the private key. Once received successfully, the recipient can spend the cryptos as required.

The idea of private and public keys is mainly associated with crypto exchanges and similar decentralized platforms where the sender has to sign transactions every time while making any transaction or sending messages.

Why should you Create a Crypto Wallet?

Cryptos are the decentralized version of a digital currency. To store, manage or spend cryptos, you will need a wallet similar to how we store real-world money in payment wallets like the PayPal app and crypto exchange development company can effeciently help you develop a crypto wallet. As mentioned, cryptocurrencies like Bitcoin and other popular cryptos are stored safely on the blockchain, a peer-to-peer distributed ledger.

Being decentralized, blockchain allows anyone to enter the ecosystem to send and receive cryptocurrencies. Considering this, we can think of a crypto wallet as a User-interface (UI) portal that acts as an entry system to the blockchain.

Now that we are done with the role of crypto wallet, let’s discuss the advantages that blockchain technology brings to cryptocurrencies. Blockchain enables anonymity, decentralization and security. Besides these benefits, experts always consider financial gains as the primary driver of high crypto adoption.

People nowadays prefer investing in DeFi products and cryptos more than investing in the digital form of real-world money. Therefore, the demand for users on blockchain-based platforms like crypto exchanges, decentralized lending platforms, and innovative fintech products. Crypto wallets are the only way to provide users access to these platforms, allowing them to utilize their benefits. From major banks to startup enthusiasts looking to leverage crypto trading systems and scale better growth.

What are the Different Types of Crypto Wallets?

Based on the private key mechanism, two types of crypto wallets are popular worldwide hot wallets and cold wallets. Also, wallets can be custodial or non custodial crypto wallet. Returning to the hot wallets, they are designed to be easy to use and suitable to handle transactions daily. Cold wallets are like vaults as they store cryptocurrencies with robust security. Let’s take a look at different types of wallets.

1. Paper Crypto Wallets

   
   Paper wallets follow an online approach to store cryptocurrencies where the public and private keys are printed on paper and then stored in a safe place.

However, this form of wallet makes it a little complex for users to access crypto because digital money is built to run on the internet.

2. Hardware Wallets

   
   Hardware wallets store keys in a thumb-size drive that can be kept safe somewhere and cannot be connected to the hardware device whenever there’s a need to store or transfer the cryptos. The idea behind introducing a hardware wallets is to maintain the security and convenience of the wallet simultaneously. To make transactions, you must ensure that your hardware wallet is correctly plugged into your computer.

3. Software or Digital Wallets

   
   software wallet can be downloaded and accessed on any compatible device. Such software wallets support mobile and desktop devices and are accessed online as multifunctional cryptocurrency wallets. However, software wallet are categorized into three main types of wallets; mobile wallets, desktop wallets, and online wallets (web wallets).

4. Desktop Wallet

   
   A desktop wallet is a cold wallet that safely stores private keys into the wallet users’ computer system, generally called cold servers. One of the main benefits of using a desktop wallet is that you can unplug these wallets from the server as an offline wallet if needed.

5. Mobile Wallet

   
   A mobile crypto wallet works similarly to the online crypto wallet in terms of features, functions, and user experience, but these wallets are designed specifically to work on mobile device. Mobile wallets are easy to download and install on mobile phones with user-friendly interfaces that help users do transactions quickly.

6. Online Wallet

   
   Online wallets are another popular type of hot wallet that provide users with the freedom to access the wallet from their preferred devices.

What are the Top Features of a Crypto Wallet?

The best crypto wallet you develop must cater to the personal and investment needs of the targeted users. From functionalities to security and user interface, the Following are the top features that a full-functional crypto wallet must have.

1. Multi-Factor Authentication

   With the growing popularity of cryptocurrency wallets and many advanced wallets being developed, crypto wallets are prone to security attacks. Considering this, wallet developers must enable two-factor or multi-factor authentication. These authentication features add additional security apart from username and password that most conventional wallets do not provide.

2. Automated Logout

   The most prominent sign of a safe and powerful crypto wallet is its ability to log out whenever suspicious activity is detected automatically. Wallet developers might think this feature can be annoying to wallet users; the same is required to reduce the wallet’s possibility of being hacked or granting access to outsiders. As a wallet developer, you can research the ideal time duration for inactivity. Once the duration exceeds, the app must automatically log out even when the app is closed.

3. QR Code Scanner

   QR code scanner powers your crypto with speed, security, and simplicity, allowing the wallet developers to do transactions easily. When a wallet has a QR code scanner integrated, users can automate scanning and public key and thus complete the transactions with a single click.

4. Paper Wallet Support
