What is a Blockchain Wallet?
A blockchain wallet is a digital tool to manage cryptocurrencies like Bitcoin, Ethereum, ONI and many others. It's akin to a digital bank account, enabling users to send, receive, and manage their digital currencies. It ensures secure transactions using cryptographic methods and maintains user privacy and identity.
Key Characteristics
User-Friendly: Designed for easy use, resembling conventional digital wallets.
Highly Secure: Ensures the safety of funds through cryptographic security.
Cross-Border Transactions: Facilitates global transactions without intermediaries.
Low Fees: Generally offers lower transaction fees compared to traditional banks.
Multi-Currency Support: Allows handling of various cryptocurrencies.
How Blockchain Wallets Work
Blockchain wallets operate using a combination of private and public keys:
Public Key: Similar to an email address, it's shared to receive funds.
Private Key: Acts like a password, kept secret to authorize transactions.
Understanding Keys
Private Key: A secret key used to access and manage funds. It's crucial to keep this key secure, as its exposure can lead to the loss of cryptocurrencies.
Public Key: An address shared publicly to receive funds and interact with dApps.
Wallet Functionality
When someone sends you cryptocurrency, they are signing off ownership of an asset to your wallet’s address.
To spend these funds, the private key stored in your wallet must match the public address the currency is assigned to.
Types of Blockchain Wallets
Hot Wallets
Online Wallets: Accessible through the internet, ideal for frequent transactions.
Mobile Wallets: Designed for convenience and accessibility on mobile devices.
Desktop Wallets: Installed on personal computers, offering a balance between security and accessibility.
Cold Wallets
Hardware Wallets: Physical devices (like USB drives) storing private keys offline.
Paper Wallets: Physical printouts of both public and private keys.
Cold vs. Hot Wallets
Hot Wallets: More convenient for regular transactions but less secure due to internet exposure.
Cold Wallets: More secure as they store keys offline, ideal for storing large amounts of cryptocurrencies.

Receiving Funds: Share your public key to receive cryptocurrencies.
Sending Funds: Use your private key to authorize outgoing transactions. This happens automatically when you sign a transaction.
Security Measures: Always back up your wallet and keep your private key confidential.
