Wallet
Software or hardware that stores your private keys and lets you send, receive, and manage cryptocurrency.
A crypto wallet doesn't actually "store" your coins. Your USDC lives on the blockchain. What the wallet stores is your private key, which proves you own those tokens and lets you authorize transactions.
Wallets come in several forms. Software wallets (apps like Coinbase Wallet, MetaMask, or Phantom) run on your phone or browser. Hardware wallets (like Ledger) store your keys on a physical device for maximum security. Exchange accounts (Coinbase, Kraken) are custodial, meaning the exchange holds your keys for you.
The wallet you choose depends on your priorities: convenience, security, and which blockchains you need to support.
