Web3 Made Simple
Web3 can sound complicated. Start with one simple idea: it is a way of building online systems where users can have more control and ownership.
The short version
Web3 is a name for online tools built on blockchains, which are shared records kept by many computers instead of one company. These tools include digital wallets, tokens, and apps you sign into with a wallet instead of a password.
You can learn all of this without buying anything. In fact, we suggest you learn first.
Control comes with responsibility
There is often no "forgot password" button. Keeping your keys safe is up to you.
Ownership is more than a picture
A token is a record. What it gives you depends on the project and its terms.
Learn before you spend
Understanding the risks first protects you from the most common mistakes.
