A BNB wallet is a digital tool that allows you to store, send, receive, and manage Binance Coin (BNB) and other tokens compatible with the BNB Chain (like BEP-20 tokens). It doesn't actually "hold" your crypto, but rather stores the private keys that grant you ownership and control over your assets on the blockchain.

These wallets come in various forms, including:

* Hot wallets: Connected to the internet (e.g., mobile apps like Trust Wallet, browser extensions like MetaMask). Convenient for frequent transactions.

* Cold wallets: Offline storage (e.g., hardware wallets like Ledger, Trezor). Offer higher security for long-term holdings.

BNB wallets are essential for interacting with the BNB Chain ecosystem, enabling activities like paying transaction fees, participating in DeFi, and accessing decentralized applications (dApps).
