Bonding Curve Plot

How to Visualize the curation bonding curve for a given subgraph from https://testnet.thegraph.com

if you'd like to learn more here are links to the video where it was first explained and a calculator to play with the variables yourself:

A list of all current subgraph addresses can be found here:

If you signalled a subgraph and know the amount of GST you received

  • Go to the tx of the contract interaction
  • Click on the Graph Curation Share and use that contract address to visualize the curve

Subgraph Address
Uniswap 0x130d022e85c74c6bdc40eaa4cf483db4e198a979
Compound 0x09a1e9751396155424e5ab56425ada306935dbb4

Requirements

  • python (3.4+)
  • beautifulsoup4
  • selenium
  • matplotlib
  • chromedriver
pip3 install beautifulsoup4
pip3 install selenium
pip3 install matplotlib
wget https://chromedriver.storage.googleapis.com/<version>/chromedriver_linux64.zip # get version number at chrome://version
unzip chromedriver_linux64.zip

# If running from a pipenv
sudo apt-get install python3-tk

Parameters

    k=1/3 # Reserve Ratio
    b=tlist["reserves"] #Current reserves under curve
    s=tlist["tokensupply"] # Current GST supply
    n=((1/k)-1) # Function of reserve ratio 
    m=((b*(n+1))/(s**(n+1))) # Shape of curve based off reserves and supply

Run

cd ./BondingCurve
./python3 BondingCurvePlot.py -h

This should print the available command-line arguments:

BondingCurvePlot.py

USAGE:
    BondingCurvePlot.py [OPTIONS]

FLAGS:
    -h, --help       Prints help information

OPTIONS:
    -n, --name <name>                        Name to save subgraph as
    -s, --subgraph <subgraph address>        Subgraph address
    -a, --address <personal address>         Personal wallet address [OPTIONAL]

Example Usage

python3 BondingCurvePlot.py -n Compound -s 0x09a1e9751396155424e5ab56425ada306935dbb4
