hdp-cairo-dev

The hdp-cairo-dev Python package abstracts all necessary Python dependencies and supported custom modules for Cairo1 Sierra files. It provides a convenient setup for a complete cairo-run environment, enabling the execution of the Herodotus Data Processor (HDP).

To fully utilize the hdp-cairo-dev package and run HDP, two additional components are required:

  1. Locate the Compiled HDP Cairo Program: Ensure the hdp.json file is in the directory from which cairo-run is expected to be executed.
  2. Install the cairo1-run Rust Binary: Obtain this from the cairo-vm/cairo1-run repository.

Package Components:

  • Tools: This package includes class definitions and functionalities for fetching Blocks and Transactions, along with a set of utilities for developers.
  • hdp_bootloader: A fine-tuned implementation of the Cairo0 bootloader for HDP, enabling dynamic loading of Cairo1 bytecode modules. This allows for the definition of aggregate functions in the Cairo1 language.
  • Compiled Cairo1 Modules: A set of compiled Cairo1 modules used as aggregate functions within the HDP function set.
