Your key to the crypto ecosystem — understanding custody and security

Crypto Wallet

A crypto wallet is software (or hardware) that stores the private keys used to sign blockchain transactions. Importantly, it does not store coins — the coins exist on the blockchain. The wallet stores the cryptographic keys that prove ownership and authorize transfers.

How It Works

Every crypto wallet has a public key (your address — share it freely to receive funds) and a private key (your secret — never share it). When you send a transaction, your wallet signs it with your private key; the network verifies the signature using your public key. Wallets are categorized as: Hot wallets (software, connected to internet — MetaMask, Phantom) for active use; Cold wallets (hardware, offline — Ledger, Trezor) for long-term storage.

Why It Matters for Investors

Understanding wallets is fundamental to crypto ownership. Exchanges like Coinbase or Binance are "custodial" — they hold your private keys, meaning you don't truly own your coins (as FTX users learned in 2022). Self-custody wallets give you full control, but also full responsibility. The phrase "not your keys, not your coins" summarizes this perfectly.
