##### scalable event scanners and infrastructure for on-chain analysis and machine learning models training.
## infrastructure
* **[💎 token-scanner-api](token-scanner-api)**:
- a mvp for a **scalable event scanner cli and api for ethereum**, through indexing and parsing blocks data. this is the first step for training **machine learning models on the chains** (e.g., high-frequency trading with deep learning).
