What is a Crypto Wallet?
/ΛwΙlΙͺt/ - A digital tool for storing, sending, and receiving cryptocurrency
A cryptocurrency wallet is a software application or hardware device that allows users to securely store, send, and receive digital currencies. Unlike traditional wallets that hold physical cash, crypto wallets store private keys - the cryptographic codes that prove ownership of blockchain assets. Wallets interact with blockchain networks to enable transactions and provide a user-friendly interface for managing crypto assets.
π Keys vs. Coins
Important: Crypto wallets don't actually store your cryptocurrency. They store the private keys that prove ownership of your coins on the blockchain. Your crypto assets exist on the blockchain itself.
