Blockdaemon's Ubiquity API lets you fetch data from different blockchains easily, using a simple API call. In this basic app, we'll use Ubiquity to easily get the gas prices (fast, medium, slow) from 4 different blockchains:

1. Bitcoin
2. Bitcoin Cash
3. Ethereum
4. Litecoin

We will fetch both the mainnet and testnet gas prices of each chain. You can reference the gas fee API documentation here.

To use this app, git clone the repo.
Run npm install, add a .env file in the root folder and obtain a Blockdaemon API key.
Open the .env file and add the API key like so:
REACT_APP_API_KEY=yourapikeyhere (without " or ')
Save the .env file and run npm start, allow to open port 3000 if needed.
The app will now load in your browser.

The app usage is very simple.
First, get the data by using the Fetch data button.
Make sure to open the console to see the different events that are logged.
Once that's done, press the Show gas prices button to see the gas fees for the 4 different blockchains.

This project was bootstrapped with Create React App.
