- 01What is a crypto wallet?ENA crypto wallet is an app or device that stores your private keys and uses them to sign transactions. Your coins never sit inside it: they are records on a blockchain, tied to addresses. The wallet reads those records to show your balance and signs the messages that move the coins.
- 02What is a seed phrase?ENA seed phrase is a list of 12 or 24 ordinary words that encodes the master secret of a crypto wallet. Typed into a compatible wallet, it rebuilds every private key and address you had. Anyone who sees it can take your coins, so it belongs on paper or metal, kept offline.
- 03Hot, cold, custodial: the types of crypto wallet.ENCrypto wallets split along two lines. In a custodial wallet, such as an exchange account, a company holds the keys; in a non-custodial wallet, you do. Hot wallets keep keys on an online device and suit small, frequent payments. Cold wallets keep keys offline, usually on a hardware device, and suit larger amounts you rarely move.
- 04How to choose a crypto wallet.ENChoose a crypto wallet by working back from what you will do with your coins. Decide who should hold the keys, check that the wallet supports the exact networks you use, look at how it backs up and recovers, and add up what it costs. Then test it with a small amount before you move more.
- 05How to send and receive crypto.ENTo receive crypto, you share an address from your wallet for the right coin and network.
