Wallet

The wallet is the place where your coins are stored. You can also send and receive coins. The wallet is also the place where you will find your walled unique identifier. This is like your account number: If someone likes to send you money, this is the number you need to provide to them.

A wallet is a tool running on your computer, mobile or tablet. There are also hardware wallets out there which mostly connect via USB interface to your computer.

There are also custodial wallets, when you place your coins or tokens on an exchange. Then the private keys are not yours, but the exchange’s.

Remember always the phrase: “Not your keys, not your coins.” Only use custodial wallets if you really trust your custodian.
