About the gastracker
The Gas Tracker Bot was built by Dave Appleton in May 2020 when DeFi farms started capturing the imagination and the pandemic kept everybody at home. The Constantinope (or was it Istambul) hard fork caused gas prices to drop and DeFi moved to Polygon so the project was closed down.
You can find the code on Github
