Instructions

The plugin can be used in frontend and in the backend.
# What is the difference between "Web3 Manager" element and "Web3 Backend" actions?
Web3 Manager - all functions runs in the frontend in your browser
Web3 Backend - all functions runs in the Bubble backend server

# How to use it in FRONTEND?

Add the plugin element "Web3 Manager" on the page. Make sure it is not located in a hidden element or popup.

# How to use it in BACKEND?
All backend actions are available with the prefix "Web3 Backend" in the actions name.

# Where to find RPC URLs?
https://rpc.info/

# Is it safe?
Our reputation is on the table, the plugin only works with the official web3.js code, it doesn't have any other scripts.
Regarding the private key, it is up to you where to store it to be used in plugin.
For example, you can store in Bubble database, but make sure you have set the right Privacy Rules, and perhaps, use some form of encryption.

This is a very powerful plugin for developing web3 related apps. I contacted the plugin author about a feature request and they came out with a new update with this feature within a few days, solving a problem I was having. Great plugin and Author.
