A crypto wallet is a digital tool that allows users to store, send, receive, and manage cryptocurrencies such as Bitcoin, Ethereum, and stablecoins.
Unlike a physical wallet, a crypto wallet does not store actual coins. Instead, it stores private keys that prove ownership of digital assets on the blockchain.
In simple terms:
A crypto wallet gives you control over your digital assets.
How Does a Crypto Wallet Work?
Crypto wallets interact with the blockchain to manage transactions.
Here’s how it works:
- The blockchain records ownership of crypto
- Your wallet holds the private keys
- Private keys authorize transactions
- Public addresses receive funds
If you control the private keys, you control the crypto.
Public Key vs Private Key (Simple Explanation)
Public Key (Wallet Address)
- Used to receive crypto
- Can be shared safely
- Similar to a bank account number
Private Key
- Used to sign transactions
- Must be kept secret
- Similar to an ATM PIN
Never share your private key or recovery phrase.
