Today, hundreds of crypto wallet apps (often called digital wallets) exist to help users interact with blockchain networks and manage crypto assets. Just as web browsers simplified internet access in the 1990s, wallets bridge the gap between users and decentralized technologies.

What Does a Crypto Wallet Actually Store?
Contrary to physical wallets, crypto wallets don’t store digital assets like Bitcoin or Ethereum. Instead, they secure:
- Seed phrases: A 12–24-word backup to restore access.
- Private keys: Cryptographic proofs of ownership.
Losing these means losing control over your assets—even though they remain on the blockchain.
