The cryptocurrency wallet works similarly to the safety deposit box. The only difference is instead of physical keys, users will own digital keys.

Every cryptocurrency wallet will have a private key and a public key. The public key is nothing but the address of the wallet. The private key or the master key is the password of the wallet.

The private key takes the form of hexadecimal codes, something like “2739020jsi82920yskw”. It is generally a random mix of numbers and characters. The wiser way to safeguard your private key is by writing down or printed on a paper.

It is essential that if you own a cryptocurrency wallet, you need to take appropriate steps to secure your private key backups. The wallet owner will need the private key to access their asset and authorize trading from their wallet.

So it is important not to lose them or share with anyone. It is better to always keep them somewhere safe where you can retrieve when necessary.

A blockchain wallet is a computer software or application that enables crypto users to preserve and conduct transactions with their cryptocurrencies by interacting with the native blockchain network. Every crypto transaction is recorded on the blockchain network. When it comes to the blockchain wallet, the transaction becomes much more encrypted and secure than other wallets.

To understand the process of cryptocurrency transactions in a blockchain wallet, let’s have a glance at its workflow!

Workflow Of Blockchain Wallet
Blockchain is a distributed ledger that logs transactions with timestamps in chronological order. Every cryptocurrency has its native blockchain network to record the transactions. The transactions are stored in data blocks of the blockchain comprising of pre-hash, hash, nounce, and data values. Every transaction is verified and approved by the community peers called miner nodes before adding into the blockchain ledger.

The entire crypto community can access the blockchain network, and hence, the transactions are transparent and traceable. Blockchain is immutable; therefore, transactions once approved can’t be modified. The blockchain wallet transactions are based on two major cryptographic keys: Public and private keys.

Public keys are similar to email addresses, whereas private keys are close to our passcodes. Crypto owners share the blockchain wallet’s public keys to send or receive cryptocurrencies, but not private keys. When the crypto transaction occurs, the blockchain wallet’s private key matches with the public address of the particular cryptocurrency, and then it’s legally signed-off from the ownership. Once the transaction is complete, the crypto balance changes in the sender and recipient wallets.

You have various options of blockchain wallet in the crypto market space to store your crypto coins. Let’s scrutinize the types of blockchain wallets available in the market to preserve the crypto assets!

What is a Bitcoin Wallet?

A Bitcoin wallet is a digital wallet to store your Bitcoins. A crypto-based company can provide you with the best bitcoin wallet development service in case you are looking for one. There are different types of wallets: software wallet, online wallet, e-wallet, hardware wallet, and paper wallet. It is important to safeguard your wallet to protect them from security threats and concerns. There are various methods and techniques used to secure the wallets.

Hardware Wallet

Storing your Bitcoins in a Hardware wallet is one of the primary steps that you can consider. This method is also known as the ‘Offline Mode’ since it does not require a link to the Internet. It is advised that you should not store a large number of currencies in the Hardware wallet. You can split the assets and keep a small amount online for trading purposes, and the second part can be stored in the wallet.

Backing Up your Wallet

Create backups of your wallet to remain on the safer side in case the device or data gets lost. The backup process includes Bitcoins stored in the Hardware wallet and the amount kept for trading purposes. You can always recover your stolen wallet if it is encrypted.

Always remember to back up your entire Bitcoin wallet to shield it against system failures and human errors. Some wallets contain hidden private keys internally. If you back up only those private keys and not the whole wallet, you will not be able to recover your funds on the whole.

Wallet Encryption

Encrypting your Bitcoin wallet gives an additional layer of security. You can encrypt the wallet using a passphrase that allows you to lock your coins. It becomes difficult for the hacker or other parties to steal your assets unless they know your secret phrase. In case you are using a mobile device or a laptop to initiate a Bitcoin transaction, then encrypting your wallet is the first thing you have to do.


Multi-Signature is one of the top-notch security standards that will help ensure that your Bitcoin wallet is safe. It is a method in which all the transactions have to get approval from the owners. Any organization can permit access to its Bitcoin wallet. But the withdrawal of funds can be made under only one condition that ‘3 to 5 people should sign the transaction.’ A Bitcoin wallet embedded with the multi-signature facility allows a user to take control over his money, thus preventing thefts.

2FA (Two Factor Authentication)

One of the best techniques to secure a Bitcoin wallet is two-factor authentication (2FA). This process is considered flawless because it requires two pieces of information before it cedes access to the wallet. Even if a hacker guesses or obtains your password somehow, he would not be able to access the wallet without the Two Factor code.

Before all that, let’s understand what a cryptocurrency wallet is and then about the multi-currency crypto wallets. A crypto wallet is a software program that interacts with the user and other multiple blockchain platforms. Besides doing this, it also stores private and public keys.

So, building the crypto wallet intuitively is mandatory for traders.

In this blog post, let’s scout around the challenges faced in the crypto wallet development process!

Challenges faced in crypto wallet development
Hectic than conventional payment systems
Conventional payment systems like credit/debit cards, bank transfers are tuned to an extensive level with years of experience. Here’s the list of some easy conventional payment processes, whereas the crypto transaction does not have.

The cancellation of a transaction becomes easier and simple in conventional payment methods. A crypto transaction can’t be canceled easily. Moreover, the secret private keys lost once can never be recovered in the wallet app.
The utilization of conventional payment methods is limited, and hence there is no threat of losing assets completely, whereas, in the crypto space, there is no transaction limit.
The loss in conventional payment systems has the possibility of recoveries at least to a minimal amount, whereas the crypto assets once lost is lost.
Conventional payment systems have prevalent fraud detection techniques for certain patterns of suspicious transactions. In crypto payment systems, even though there is community governance in prevalence, there exists fraud. As the crypto wallet, private keys are completely owned by the owners, the community does not take responsibility for the fraudulent transactions.
Security Aspects
The Crypto wallet app stores the public and private keys to interact with the native blockchain network. The crypto owner completely holds control over the private keys and the transaction. The wallet app encrypts the private keys with cryptographic hashes, and the assets are stored securely.

While building customized wallet apps, you can enhance the security of your assets by enriching the multi-factor authentication. In crypto wallets, the private keys are generated in real-time; hence it has unique cryptographic hashing algorithms to secure your assets on the blockchain network.

Recovery backups
If you own a reasonable amount of crypto assets in a single wallet, then storing it in hot wallets are extremely vulnerable. The crypto owners must build both hot and cold wallets to secure the assets. Minimal amounts of crypto coins required for instant transactions alone must be stored in hot wallets like mobile or web apps. The remaining bulk amount of crypto coins can be stored in cold wallets with secured offline private keys.

Complex and extensive knowledge
The customized crypto wallet applications must be developed from scratch, and it must be packed with advanced features to enhance your secure trading experience. The complexity of the crypto wallet app has increased enormously, with intuitive UI, security features, front-end programming language, and much more. Hence, its mandate to build the crypto wallet app with an eminent team of blockchain experts.
