What Is a Crypto Wallet App?

A crypto wallet app is a software application that stores the private keys required to access and manage cryptocurrency holdings. Unlike traditional wallets that hold physical money, crypto wallets store cryptographic keys that allow users to sign transactions on the blockchain.

Crypto wallet apps enable users to:

• Store cryptocurrencies securely
• Send and receive digital assets
• Track balances and transaction history
• Interact with decentralized applications (dApps)
• Buy, sell, and swap cryptocurrencies

How Does a Crypto Wallet App Work?

A crypto wallet app works by generating and managing a pair of cryptographic keys:

Public Key

The public key is used to create a wallet address that can be shared with others to receive funds.

Private Key

The private key is used to authorize and digitally sign transactions. It must be kept confidential at all times.

When a user sends cryptocurrency, the wallet app signs the transaction with the private key and broadcasts it to the blockchain network. The blockchain verifies and permanently records the transaction.
