What is a Crypto Wallet? A crypto wallet is a software or hardware tool that stores the private keys needed to access, manage, and transact with cryptocurrency and digital assets on a blockchain.
Crypto Wallets Explained Despite the name, a crypto wallet does not actually store your coins the way a physical wallet holds cash. Your crypto never leaves the blockchain. What the wallet stores is your private key, the secret code that proves you are the owner and gives you the right to move those assets.
Think of it like a safe deposit box at a bank. The money is not inside the box itself. The box holds the key that lets you access your funds. Lose the key and you lose access. Someone else gets the key and they can take everything.
That is why keeping your private key secure is the most important rule in crypto.

What is a seed phrase? A seed phrase is a sequence of 12 to 24 words that serves as the master backup for a wallet. Anyone with the seed phrase has full access to the wallet and its assets.
What is the difference between a custodial and non-custodial wallet? A custodial wallet is managed by a third party like an exchange, which holds your keys. A non-custodial wallet gives you full control of your own private keys.
