A paper wallet is a document containing a private and a public key used to manage your cryptocurrencies. Safer payments. Payments within the blockchain network are transparent, secure, and irreversible. Moreover, they are anonymous. This combination will almost completely eliminate the risk of fraud.

Speeding up international transactions. It still takes a long time to make international payments as each intermediary bank checks the transaction data and thus delays the receipt of the payment. The blockchain network is transparent and secure, so cryptocurrencies can be sent and received almost instantly.

No governmental control. This is a rather dubious advantage since cryptocurrencies in the hands of cybercriminals and lack of control is not the best scenario. However, blockchain enables companies to earn money honestly and allows users to spend it at their discretion. Attracting modern users. The majority of the public is not yet ready for the full adoption of cryptocurrencies, but a number of progressive users have long appreciated their benefits.

If your business is aimed at tech-savvy users, they will appreciate the idea of a custom cryptocurrency wallet. Despite the seeming complexity of the blockchain technologies, the answer to how to make a crypto wallet app is simple. Start by analyzing its main features. Main stages of a cryptocurrency wallet app development Here is how to make a mobile crypto wallet app in three stages: Use of Bitcoin libraries for Android and iOs.

Since most cryptocurrencies are open source, you don't need to reinvent the wheel to create a cryptocurrency wallet for your personal use. Your cryptocurrency wallet development company will suggest which technology suits your project best. Using a distributed ledger API will allow you to easily sync your crypto wallet with the blockchain ecosystem.

Integrate bitcoin as the payment option. If you want to give your users the ability to use bitcoin to make payments on your website, you need to integrate bitcoin payments into your cryptocurrency wallet using special services such as BitPOS or BitPay. Image How to make your cryptocurrency wallet app secure Currently, transactions based on blockchain principles are the most secure transactions. However, due to the high cost of bitcoin, user data and access keys need reliable protection.

Here are some additional measures for this: Wallet backup. It is necessary to have several mobile wallet backups stored in several hard-to-reach places. Two-factor authentication. A unique pin-code or biometric data may be used as the second factor. Diving into More Technical Approach If you are serious about launching your crypto wallet for your funds, here's a more technical take that you need to remember.

Use open-source libraries. Set your chosen wallet name and check permissions. Integrate third-party programs with the digital wallet. Think of interesting features that you want to add to your crypto wallet. Code the app and combine it with the database that you have. Make sure to establish a user-friendly UI.

Do a lot of test runs before launching it to the public.

It stores all the transaction records in the immutable blockchain network. It operates in the form of a software program containing your private and public keys. The private key stored in your wallet must match the public address the currency is assigned to for unlocking the funds and utilizing them for various purposes.

The public key will be used to receive the funds and can be searched in the distributed ledger. The private key is used to sign the transactions and prove that the user owns the related public key. What are the Types of Cryptocurrency Wallets? Desktop wallets can be downloaded and used on a PC or laptop.

They are accessible only from the single computer on which it was originally installed. They are mostly secure except in cases of a virus or a hacking attack on your computer. This would lead to the loss of all of your funds. Popular examples of a desktop wallet would be Armory and Bitcoin Knots. Virtual wallet for cryptocurrency is also called an online wallet. They operate on the cloud and can be accessed from any location using any device without any restrictions.

They are very convenient to use as private keys can be stored online. But, sometimes they are vulnerable to hacking attacks and chances of theft as they are indirectly controlled by a third party. Mobile wallets can be utilized via an app on your smartphone. They are accepted by retail stores and supermarkets for processing various payments. They usually have limited cold storage facilities than desktop wallets. They have robust security measures as they are stored online and transactions can also be executed online.

They can support different digital currencies and are seamlessly compatible with several web interfaces. Paper wallets are easy to use and are highly secure. The software will automatically generate your private keys and public keys which can be printed. A user can easily transfer funds from their software wallet to the public address of their paper wallet.

You can enter your private keys or scan the QR code on the paper wallet for transferring funds from it to your software wallet. A Bitcoin paper wallet can be printed at bitaddress org. How do you Secure Assets in a Cryptocurrency Wallet? Notify your users to keep their passwords and private keys securely.

If unauthorized access has been granted funds will be swindled in no time without any chance of recovery. Hence, tell them to ensure that only they have access to their respective password and private keys. Enable two-factor authentication as it will act as an extra layer of security.

Even if someone happens to get access to the password and private key, it will save users from the potential misuse of their wallet as the secret code containing a few digits sent to them is needed to log in to the cryptocurrency wallet.

Ensure that you do not deposit all your funds in one wallet. Distribute all your investments in multiple wallets simultaneously to get the benefits of diversification and division of risk. This will add the latest security enhancements. Some wallets like Armory are multi-signature enabled and have sufficient cold storage facilities. All the private key data of the users are stored in secure offline computers. They follow GPU-resistant wallet encryption. The code can be obtained from platforms like GitHub.

Set a password for the wallet and do not share it with anyone. Set up a private key so that you alone can access the funds. We have chosen a testnet server for this example, but this decision should be based on the purpose of the dApp. However, this might take a while, but worry not; the server will be finalized in a couple of minutes.

This we can accomplish through HTML code, and in this example, we have two different files; one for the sign-in page and one for the dashboard itself. The code in this file is based on a simple Bootstrap sign-in template that we used to build around. However, a critical element of this file worth noticing is that we connect our SDK to Moralis, which looks like this: Moreover, the majority of this code is the fields and buttons of our crypto wallet, which are the elements that we, later on, will reference when writing the JavaScript code.

Furthermore, at the bottom of the file, we also find some vital code implementing some JavaScript files making the template work as it should. In this file, we have a bunch of different functions enabling our wallet to work as intended. As we mentioned, we are going to focus on the functions needed to enable transfers between accounts. However, for a full overview and the complete file, you can again visit the GitHub repository.

This basically connects our project to our Moralis server that we created in the first step. All we need to do is implement these two elements by copying and pasting them into our code. Along with this, we have some essential functions for logging in, logging out, rendering content, hiding content, etc.

These are all pretty straightforward functions that are easy to implement. Without the platform, this task would have been a lot more complicated, and this is only one instance in which Moralis comes in handy. Step 4: How to Build a Crypto Wallet — Transfer Functions In this crypto wallet, we have a few different functions for transferring tokens.

However, as you can see from the code, this function takes an argument in the form of an object. Transferring ERC Tokens The function for transferring ERC tokens is somewhat more complicated; however, just as with transferring ETH, only a single line of code is necessary to implement the feature.

This information is then used to create an object by taking the variables as properties. After this, the code simply adds the receiver and the contract address. To improve the user experience of our applications, we are also going to create a function that allows us to fetch this information directly from the blockchain.

The print screen above shows you how the UI for transferring tokens. As you can see, the interface prompts users for the amount, which address they would like to transfer the tokens too, the decimals, and the contract address.

With the balances at hand, the functions go through each token, creates a content block with the correct information from the blockchain, and then sends it directly to the frontend of the application. This is the information that is available to the users below the input fields.

If the user clicks any of these buttons, the function automatically fetches both the decimals and the address of that specific token and automatically fills in these fields for the users. The reason for this is that we only added functionality to get this information for the Rinkeby blockchain. However, you can easily use the same structure to expand the function, making it compatible with other chains.

So, this is it for this tutorial and the transfer functions. How to Build a Crypto Wallet in 4 Steps The process of how to build a crypto wallet is relatively easy with the Moralis platform. We can utilize the already developed backend infrastructure to set up a server and use the Moralis SDK to make the process more accessible.
