🛠🪙 token scanner api and cli
👉 this project implements a cli tool that indexes transfer events for a particular token, and is deployed to a restful api for fast balance and ownership statistics retrieval. this is the first step for training machine learning models on the chains (e.g., high-frequency trading with deep learning).
📚 more details can be found in my mirror post, quant #3: building a scalable event scanner for ethereum.
setting up
installing dependencies
because of some of the dependencies in this code, we will be developing on a python3.9 environment (install here if you don’t have that version on disk):
virtualenv -p /usr/local/bin/python3.9 venv
source venv/bin/activate
pip3 install -r requirements.txt
adding environment variables
create a .env file and add an RPC_PROVIDER_URL to connect to ethereum mainnet nodes (for example, from this list):
cp .env.example .env
vim .env
installing the package
make install
running
indexer -h
development
deploying in production
we use vercel to deploy this app:
vercel login
vercel .
