# The Solution

**What is SELF?**&#x20;

SELF is a unique and irreplicable online identity which links all things crypto, such as your wallet, NFTs, important documentation, and the endless possible uses of blockchain utility. SELF can be your nickname, dog's name, company name, or whatever you choose. When you create a SELF identity, all you need to send and receive crypto is your unique SELF identifier.&#x20;
