Introduction to Wallets

A crypto wallet is not a container that holds coins on your phone. It is software that holds your keys and uses them to sign transactions on your behalf.

Your public address is what others see and send to. Your private key is what proves you control that address. Lose the key and the assets are gone — there is no bank to call.

This course walks through the wallet types, backup methods, and security habits that turn key ownership into practical self-custody. The goal is not to memorize jargon — it is to know what you control and what can go wrong.
