Presenting before you EtherEyes, an award winning hackathon project that enables users to make cheaper transactions by predicting the gas price and providing timely gas price notifications.

Improved cost efficiency:

Knowing the expected gas price in advance allows users to make informed decisions on when to execute transactions. This can help reduce costs and increase overall efficiency by avoiding times of high gas prices.

Better planning:

Predictive models can help project future gas prices, allowing businesses and individuals to plan accordingly and minimize any potential negative impact on their operations.

Features

  • Notification about current gas prices
  • Suggests user to buy when lowest gas price reached
  • Set urgency of your transaction
  • Toggle Notifications
  • Graphical data representaion of gas prices
  • Dark theme :)

Installation

Dependencies

  • Python version 3.7-3.10 (recommended 3.9)
  • yarn
  • Metamask Flask

Setting up the virtual environment

We recommended you using conda as environment manager, for installation instruction refer https://conda.io/projects/conda/en/latest/user-guide/install/index.html

Create a python 3.9 environment

conda create -n py39 python=3.9

This will prevent any dependency conflicts with your global level python installation

Installing requried libraries:

pip install -r requirements.txt

Setting up servers

cd ~/Desktop
git clone https://github.com/aritroCoder/transaction-insights.git

Setting up config

Open the file named key.json in transaction-insights/ directory, and write in the file (Create an API key from https://owlracle.info/eth and paste it in place of your_key)

{
  "key": "your_key"
}

Then copy and replace(when prompted) this file to transaction-insights/packages/snap/ and transaction-insights/packages/site/src/ directories

Starting the python server

cd ~/Desktop/transaction-insights/
uvicorn server:app --reload --port 5000

Open a new terminal to start yarn server

cd ~/Desktop/transaction-insights/
yarn install
yarn start

Done both the servers are running now..

Getting Started

Working

We collect live gas price data as a list of around 200 candlesticks (each candlestick is an aggregate of the past 30 minutes of data) using the Owlracle API. This gives us the timeseries data of past 100 hours of gas prices.

We then use a popular time series forecasting model called SARIMA or Seasonal ARIMA from the statsforecast package on the timeseries data to predict the lowest gas price expected in the next hour.

Why SARIMA?

  • A lot of literature on SARIMA for time-series forecasting in varying domains ([1],[2],[3]) stated that the performance of SARIMA is good. We also referred to a study on ethereum gas price statistics [4], where they used SARIMA and obtained promising results.
  • An alternative would be deep learning techniques which usually involve larger models which also take more time to re-train hence making it less ideal for streaming data.
