Blockchain technology has revolutionized digital currency transactions, making them more accessible and practical. However, the rise in cryptocurrency adoption has also increased cyber theft risks. Safeguarding your crypto starts with understanding crypto wallets—how they function, their types, and key selection criteria.
What Is a Crypto Wallet?
A cryptocurrency wallet stores secure digital codes (keys) required to interact with a blockchain. Contrary to their name, they don’t "hold" cryptocurrencies but instead:
- Track ownership of crypto tied to your address on the blockchain.
- Serve as a ledger for transaction history and identity verification.
How Do Crypto Wallets Work?
When crypto is sent to your wallet, ownership is transferred via two digital keys:
- Public Key: A shareable address (e.g.,
B1fpARq39i7L822ywJ55xgV614) for receiving funds. - Private Key: A secret code (like a password) that must remain confidential.

Analogy: Think of your public key as an email address (shared to receive funds) and your private key as the password (never shared).
