NFT Wallet Development: The Ultimate 2021 Guide

Share

A non-fungible token, also well-known as an NFT, is a kind of cryptocurrency token that works similarly to a digital certificate of ownership of physical or virtual assets. These tokens are unique, non-fungible digital identifiers, so they are not a payment method. They are used for buying, selling, and exchanging unique items. I.e., paintings, photos, texts, music, and videos. NFTs differ from other crypto tokens, they are unique, unlike common crypto tokens, where the token is traded on a decentralized exchange, whereas in the case of NFT, assets are traded on a special exchange called the NFT marketplace.

In the article, we will take a closer look at the way cryptocurrency wallets manage these tokens, as well as the price of developing such a product.

Latest NFT Market Statistics

2021 is not over yet, but it is already witnessing a rapid rise in the popularity of NFT. They are more prevalent than ever before, with more NFTs being created, bought, and sold. And people are willing to spend money on a digital asset that they want to claim as their own.

The market cap for global transactions of NFTS

Here is a list of some interesting numbers:

  • In 2021, the value of NFT for games decreased, but for art, it grow up.
  • Big brands like Taco Bell have started offering their own NFTs, creating digital collectables for sale.
  • In February 2021, OpenSea’s monthly sales exceeded $95 million.
  • By March 2021, the NFT trading volume on Ethereum was over $400 million.

What is the NFT Wallet App and How Does It Work?

NFTs should be stored in a secure location, such as the software cryptocurrency wallet, which is typically protected by a 12-word original phrase, password, and touch authentication. Simply put, an NFT wallet provides holders with “private keys” or passwords that give access to assets stored on the blockchain. If you are looking to start collecting NFTs, a wallet is a key tool to get you started.

Firstly, it is critical to get that the wallet itself does not contain any NFT. NFTs stored on the blockchain. Thus, the term “wallet” can be misleading, as instead of a well-known leather wallet filled with old coins and membership cards, the NFT wallet does not directly contain your assets. Just as a debit card does not store your money directly, but acts as a key to an ATM, a wallet provides a gateway to the blockchain where your funds are located. A crypto wallet contains “private keys”, passwords that allow the owner to transact on the blockchain.

Types of NFT wallets

There are several most widespread types of NFT wallets. Below, we listed the main of them.

Types of NFT wallets

✔ Web wallets
Web wallets integrate with the browser and help in storing and managing the assets. The key benefit is that they work on any computer and are easy to use. But the drawback is that they are not protected enough from hacker attacks.

✔ Hardware wallets
Hardware wallets are physical cards that can be connected to a desktop, laptop, or tablet. They help to complete a transaction without discovering the private keys as they are on the flash drive and never leave it. That’s why it is the safest solution.

✔ Mobile wallets
Mobile wallets have an intuitive interface and are perfect for daily use. They are more secure than browser extensions, but still not as secure as other options. In addition, they have some limitations due to the low speed of the hardware of standard mobile devices.

✔ Desktop wallets
Desktop wallets offer excellent functionality and allow cryptocurrency mining (not NFT, they cannot be mined). The safety of these wallets depends on how secure the laptop or desktop device is where they are installed since the private keys are typically located on the same device.

Must-have Features of NFT Wallet

The key feature of NFT wallets is reconcilability with NFT protocols. Otherwise, everything is similar to typical cryptocurrency wallets.

💰 Authorization
The basic feature that helps people register and fill out the form with their wallet access keys. Many wallets use an email address or phone number to register. Besides, users have to provide some information to protect the privacy of transactions and private information from hacking attempts.

💰 Fast and cheap processing of international transactions
Worldwide transactions take up to 5 business days as the intermediary bank verifies the transaction details, which delays payment and increases costs. There are no intermediaries in cryptocurrency networks. The blockchain verifies transactions and processes them within minutes for a small fee.

💰 Enhanced security
On networks like Bitcoin, Ethereum, and BSC, you cannot reverse an erroneous or unauthorized transaction, and the counterparty is difficult to find, so there is no way for users to receive money if it is stolen. It’s a reason why your app has to be protected from hackers, fishing, and user bugs.

💰 Sending and receiving NFTs and other assets
QR codes for fast transactions. This feature is unnecessary, but many users appreciate it as it avoids fatal errors when entering public keys to complete a transaction. Here you will need to develop a random QR code generator and scanner.

💰 Favourite addresses
This feature eliminates the need to enter public keys, making recurring transactions even faster, such as paying for subscriptions. QR codes and this feature are not needed, but people like them and they are easy to develop, which is why almost every cryptocurrency wallet has them.

💰 Transparency
Open source coding is the basis for cryptocurrency wallet software, so anyone can check the security, safety, and workflow.

💰 Confidence
Encryption technology protects the user’s data from hidden and unauthorized access. Even if somebody knows the public key, the credentials are still not available.

💰 NFC support
In case you want your wallet to work with NFT, it must support ERC721, ERC1155, Composables, dGoods, NFT Cosmos, TRC-721, BEP-721, BEP-1155, and others.

💰 Notifications
With this feature, people will get messages with important data. I.e., transaction checks, app updates, deposits, and withdrawals, suspicious activity, etc.

How to develop an NFT wallet app step-by-step

The NFT wallet differs from the traditional one as there are supplementary safety requirements. The transactions are confident and unalterable, so stolen money is almost impossible to recover. Besides, cryptocurrency wallets are open source, which places supplementary demands on security levels and measures.
