Public key
It’s your address, like an account number. It can be shared so you can receive cryptocurrencies.
What is a crypto wallet
A crypto wallet, or wallet, is where the keys that give access to your cryptocurrencies are kept. It doesn’t store the coins themselves, which are recorded on the blockchain, but the password that proves they are yours. There are wallets within platforms and wallets that you control yourself.
- Public key to receive cryptocurrencies
- Private key that should never be shared
- Balance recorded directly on the blockchain
Concept
Wallet in one sentence
Unlike what it may seem, the wallet does not store the coins inside it. Crypto is on the blockchain. What the wallet stores are the keys, which work as proof that that balance is yours.
Think of it as the keychain to your digital money: whoever has the keys can move the crypto. That’s why protecting these keys is the most important part.
How does a wallet work?
Two keys and one golden rule.
Private key or seed
It’s the access to the balance, your master password. It must be kept in absolute secrecy, never shared.
Crypto lives on the network
The coins are on the blockchain. The wallet only stores the key that authorizes moving them.
Whoever has the key has the crypto
Understanding this logic is what separates those who use crypto safely from those who get scammed.
What are the types of wallet?
What changes is who holds the key and how it is protected.
Platform wallet
Custodial: the platform, like Brasil Bitcoin, holds the keys for you. It’s the simplest option to get started.
Self-custody wallet
Non-custodial: you hold the keys yourself. It gives more autonomy, but all the responsibility is yours.
Cold wallet
An offline device to store keys away from the internet, used by those with larger amounts.
Security
How to keep your wallet secure
Never share your private key. Not even the seed, with anyone, under any circumstances.
Be wary of anyone asking for your data. No reputable company asks for your password or seed.
Store the seed offline. Written down and kept in a safe place, if you use a self-custody wallet.
Prefer regulated platforms. For custody, support, and more security.
