Simply put, a crypto address is like your bank account number, and just like a bank account number, it makes it possible for someone to send cryptocurrency to you.
A crypto wallet address is typically made up of a string of letters and numbers, for example:
$ 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNaEach cryptocurrency may use a different method to generate wallet addresses.
The address itself is produced by running additional cryptographic functions on the wallet's public key [↗].
This isn't just for security, but also to shorten the long public key into a more manageable and user-friendly string.
