What is JSON?
Jason, which stands for JavaScript Object Notation, means to mark objects in JavaScript. JSON is a standard, lightweight format for storing and transmitting data, just like XML. It was hard, don't worry at all!
Suppose you could buy a bicycle, but instead of having a dealer sell it to you! It provides you with the important features and characteristics of cycling so that you can present it with tools that you can completely build.
This feature can be sent to you as a feature-key pair: body type, size, colors and some other things. And now my opinion for the private key in wallet, many users create wallet with 12 letters or 24 letters and They put a password in the wallet, if the wallet itself hashes, you must save your EVM key in a safe place.
