Aztec Connect Data Gobbler

The Aztec Connect Data gobbler is a tool made for extracting data from the Aztec Connect system using only L1 as its source. The tool looks for new rollup blocks being published, and then pulls and decodes them.

The decoded blocks are stored in a simple key-value store (MicroKV), and the transactions can be exported to a CSV-file such that it can easily be passed into Python or similar tools.

Usage

The tool is written in Rust, and can be compiled using cargo build --release. The key-value store is written to disk for later use, and is saved in the directory passed in to --data-path or use the default.

Syncing

To sync the node, you need point it towards an L1 node (can be Infura) and can then sync it using

Synchronise the local database with the rollup

Usage: ac-gobbler sync [OPTIONS]

Options:
      --rpc-url <RPC_URL>      The RPC url to an ethereum node [default: http://localhost:8545]
      --data-path <DATA_PATH>  The path to the dir of the database [default: ./data/]
  -h, --help                   Print help

Exporting

Syncing might take a while, as the tool needs to download all the rollup blocks. Once it is done, rerunning will be much faster as it will only download new blocks.

The tool can also export the data to a CSV-file, which can be used in Python or similar tools. To do this, run

Exports all transactions to a csv file

Usage: ac-gobbler export [OPTIONS]

Options:
      --export-path <EXPORT_PATH>  The file to write csv to [default: ./export/txs.csv]
  -l, --l1-only                    Export only deposits and withdrawals
      --data-path <DATA_PATH>      The path to the dir of the database [default: ./data/]
  -h, --help                       Print help

Decoding individual blocks

Individual blocks can also be decoded using the decode command, which can be useful for getting an understanding of what is going on in a specific block.

Print the contents of a block in a semi readable manner

Usage: ac-gobbler decode [OPTIONS] <ROLLUP_ID>

Arguments:
  <ROLLUP_ID>  The rollup id of the block to decode

Options:
      --data-path <DATA_PATH>  The path to the dir of the database [default: ./data/]
  -h, --help                   Print help
