A private and public key for the transaction is saved in cryptocurrency wallet store. With multiple Blockchains there is interaction to authenticate a transaction, allowing users to purchase or sell one or several cryptocurrencies. But, what precisely happens in the backdrop that makes a secure, cryptocurrency transaction possible? Given below is the example which will provide a better understanding for this.
Example: You can assume that someone has sent you some Bitcoin or any other digital currency. When the sender does this, he is actually assigning you the owner of that currency to the address of your Blockchain wallet. Now, for you to the private key in your wallet must match the public key that the currency is assigned so that you could spend those coins. When both the keys will match, the balance in your wallet will increase. In this process, the exchange of currency is not there but a transaction is committed, recorded on Blockchain, and the changes are then seen in the wallet.

To store and reflect a transaction on Blockchains, there are three types of cryptocurrency wallets available. They are:-
These are software applications which can be downloaded on a device (either desktop or mobile) or accessed online. Depending on the type of device they are meant for, software wallets are further characterized as:
Desktop: These are wallets which can be downloaded on a PC or a laptop and can only be used from the system in which they are installed. If you don't focus on accessing the wallet anywhere then these software wallets are good to go.
Limit: Though desktop wallets are a safe choice, you should make sure that your system is protected against virus attacks (as a single susceptibility may make you lose the funds).
Online: You can access these wallets on any device(mobile, tablet, desktop) through a web browser. This is because these wallets run on the cloud.
Limit: It is a little unsafe option as the private keys for a transaction (in online wallets) are saved online and are controlled by the third party.
Mobile: These wallets provide anytime and anywhere access as they are available as a mobile app. Other than this it allows provides the ability to scan QR codes which facilitates easy and faster funds transfer. As there are a number of benefits which these mobile apps offer, mobile wallet development is famous amongst the three software wallet categories.
As there is no such system which is 100% secure, all you need to adopt is adequate security measures at your end if you are going for any of the three software wallets.

The private key of users on a hardware device (like USB) is stored in Hardware wallets. There is compatibility by these wallets with various web interfaces and allows support to multiple cryptocurrencies. For making use of these wallets, you have to connect them to any internet-enabled device, enter pin, and confirm. Hardware wallets are the securest wallet options available as all currencies are stored offline
For paper wallets, the pair of keys (public and private) are generated using a software application and are then printed to make a transaction possible. Paper wallets generally work with software wallets for buying and selling of funds.
Currencies are transferred from software wallets to the public address on the paper. And to unlock the funds, the currencies are transferred from paper wallet to software wallet. This process is called sweeping, which involves scanning QR code or adding the keys manually.
According to Wikipedia ‘, The number of cryptocurrencies available over the internet as of 7 January 2018 is over 1384 and growing.’
While Bitcoin still comprises of the biggest Blockchain network, Ripple, Ethereum, Litecoin, Carnado and other alt-coins are catching on to the users’ interest. If you or your customers need to work with multiple currencies for receiving or transferring funds, then there is no requirement of having a separate wallet for every currency.

To start with follow the example below and you will get the clarity of the process.

Blockchain Wallet Development: How to Make the Right Choice?
A Blockchain wallet is intended to simplify cryptocurrency exchange for users (which could be your client or customers)., A choice between software, hardware, and paper wallets can be made depending upon how frequent and big transactions are going to take place.
For example: If the intended audience regularly buys or sell multiple currencies, then choosing a mobile wallet is the most appropriate option. On the other hand, if your clients are sponsors (having made an investment in ICO tokens), who actually need to hold on the digital currency for a longer time, then the requirement will be met by hardware wallet. You actually need to take out time and access them for better results.
