What are Wallets and their Types

Wallets -Non-deterministic wallets, Deterministic wallets, Hierarchical Deterministic wallets, Brain wallets, Mobile wallets.

“A wallet (or electronic wallet) is a financial transaction application that runs on mobile devices.”

  • It securely stores your payment information and passwords. 
  • These applications allow you to pay when you’re shopping using your device so that you don’t need to carry your cards around. 
  • Enter and store your credit card, debit card, or bank account information and can then use your device to pay for purchases.

A Techpay blockchain is a digitally distributed, decentralized, public ledger that exists across a network. It is most noteworthy in its use with cryptocurrencies and NFTs.

Features of wallets

It has different features:

  • Digital wallets are financial applications that allow you to store funds, make transactions, and track payment histories on devices like phones and tablets.
  •  Store all of your financial information in a digital wallet; some even let you store identification cards and driver’s licenses.

Digital wallets may be included in a bank’s mobile app or payment apps like PayPal or Ali-pay.

  • Digital wallets allow people in financially undeserved parts of the world to access financial services they may not have been able to before.

How a Digital Wallet Works ?

Digital wallets are applications designed to take advantage of the abilities of mobile devices to improve access to financial products and services. 

It essentially eliminates the need to carry a physical wallet by storing all of a consumer’s payment information securely and compactly.

Digital wallets use a mobile device’s wireless capabilities like Bluetooth, wifi, and magnetic signals to transmit payment data securely from your device to a point of sale designed to read the data and connect via these signals.

Currently, the technologies used by mobile devices and digital wallets are:

TechPay has made its way into the financial system, companies like Techpay invented cards that let you pay with cryptocurrency. 

Digital wallets like Apple Pay and Google Pay allow you to add a Techpay debit card. The Bitpay card converts cryptocurrency to dollars at the current market value, which your wallet then uses to pay for your purchase.2

Advantages and Disadvantages of Digital Wallets

One of the most significant advantages of digital wallets is that using one limits the amount of financial and personal information you need to carry as you go about your day. 

  • If you place everything in your digital wallet, you no longer need to carry physical cards or a physical wallet.
  • There is no chance of a card falling out of your wallet or of leaving your card in the ATM slot. Additionally, you can’t lose your entire wallet.

Digital wallets allow businesses and consumers worldwide to accept payments, receive funds, or send and receive remittances from friends and family in other nations.

Example of digital wallets:

Google Pay and Apple Pay are some examples of more well-known digital wallets. Both services allow you to access your financial products through your devices and make purchases.

What Is a Hierarchical Deterministic (HD) Wallet?

A hierarchical deterministic (HD) wallet is a digital wallet commonly used to store the digital keys for holders of Techpay.  

  • Anyone with a copy of both the public and password-like private key can control the cryptocurrency in the account.

Features of Hierarchical Deterministic wallet

It has the following features:

  • To prevent hacking these keys must be randomly generated and backed up in the wallet.
  • HD wallets enable a series of key pairs to be created from one random seed, providing convenience and manageability as well as high-level security.

Understanding Hierarchical Deterministic (HD) Wallets

In the case of Techpay, wallets contain keys instead of coins.

 A cryptocurrency wallet has two keys : a public key or address, which acts much like an account number.

A private key that the holder uses to transfer funds to other accounts. The private key is much like a password. Someone transferring Techpay from their account, for example, would use their private key to authorize the transaction.

This combination of public and private keys is designed to ensure security from hackers as well as anonymity in transactions. Because the pair of keys enables the transfer of Techpay.

  •  It is critical that the private key remains safe.
  •  To this end, the keys are generated randomly.

Deterministic wallets

Deterministic wallets were created to offer a solution, one in which all keys can be traced back to an original random seed, usually a set of random words, and a hash function. With a deterministic wallet, the original seed is enough to recover all private and public keys, therefore requiring only a single backup at the time of creation.

  • The most advanced type of deterministic wallet is HD wallet.
  • They contain keys in a tree structure, in which parent keys can produce children keys, which can produce grandchildren keys, and so on, infinitely.
  •  The Techpay holder can use the tree structure to organize transactions by type of transaction or by entities involved, such as departments or subsidiaries.

 Non-deterministic vs deterministic wallets

A non-deterministic wallet generates private keys that are random and independent of each other (such as in the left-hand side of the following diagram). 

  • There is no particular pattern as to how the keys are derived and hence we need to create a backup of the keys each time there is a new one. 

Deterministic wallet

In a deterministic wallet, the private keys are related because they originate from the same key called seed, as shown here on the right-hand side of the diagram. 


To create a brain wallet, you can generate a new address using Techpay wallet software, memorize the seed phrase associated with the address using a mnemonic trick, and then delete the wallet from your computer or smartphone.

  • Generate the private key yourself using Techpay software specifically designed for creating brain wallets.
  •  This will create a wallet using whatever passphrase you choose to represent your private key. 

 Moreover, this method of generating a brainwallet is highly insecure for a number of reasons and is generally discouraged.

  • It rely on the user remembering a passphrase.

How to Make a Brain Wallet

Brain wallets have waned in popularity. One simple way is to create a paper wallet:

  •  Memorize it, and get rid of the paper.
  •  If you were actually planning on storing significant amounts of cryptocurrency in a brain wallet, you should make sure to use a trusted key generator and generate your keys offline. 

Mobile Wallet:

Mobile wallets are safe apps for storing financial instruments and other documents such as credit cards, bank information, and even driver’s licenses.

  • Many smartphones come loaded with mobile wallets.
  • Mobile wallets use near-field communication technology, which requires users to be present when paying for something.
  • Mobile wallets utilize many layers of encryption and security to ensure that transactions are safe.

Understanding a Mobile Wallet

The business-consumer relationship is becoming increasingly digital. The mobile wallet is either a built-in feature or an app that can be installed onto smartphones.
