Wallets · Question 1 of 7
What is a crypto wallet?
A crypto wallet is software or hardware that lets you view your holdings and authorize transactions. It stores your keys — not the coins themselves, which live on the blockchain.
What it actually holds
The common mental image — coins inside a wallet — is misleading. The coins are entries on the blockchain. The wallet holds the keys that prove you can move them.
What it lets you do
- See balances and history.
- Receive funds via your address.
- Authorize sending by signing with your key.
- Connect to apps (which still can't move funds without your approval).
Why it matters
Understanding that a wallet holds keys, not coins, is the foundation for every safety habit that follows.
A practical way to picture it
A wallet is less like a purse and more like a keyring: lose the keys and you lose access to what they unlock, even though the 'money' was never physically inside.
Risks & common mistakes
- Anyone with your keys or seed phrase controls your funds.
- Losing your keys with no backup means losing access permanently.
- Wallet apps can be impersonated — download only from verified sources.
