pull_attestations_shroomdk.ipynb uses Flipside Crypto data and Flipside's ShroomDK (SDK) to query all on-chain attestations made on the AttestationStation deployed on Optimism.

Once you have a ShroomDK API Key (requires NFT mint), store in your .env as:
FLIPSIDE_SHROOMDK_KEY = 'Your API Key'
From there, you can run pull_attestations_shroomdk.ipynb in jupyter notebooks. This will query for all attestations in Flipside's databse, and store results in a file attestation_data csv, with today's date appended to the file name.
To make any modifications to the query (i.e. specific attestations, set date ranges), modify the query in sql/attestation_query.sql
Note: These csvs will be large, so you can add something like op_attestation_data/*.csv to your .gitignore.
All attestations are stored as key : value pairs (see the code).
- decoded_key: The key of the attestation
- val: The value of the attestation (numeric).
- val_text: The value of the attestation (in text). Note: Since vlaues can be stored as either values or text, it's up to the analyst or reader to pick the appropriate decoding
- about: What address the attestation is being made about
- block_timestamp: What is the timestamp of the block where the attestation was made.
- creator: What address created the attestation (think: Is this sender trustworthy, or may this be spam?)
- tx_hash: The transaction hash of the transaction where the attestation was made.
- origin_from_address: The sender (from) address of the transaction where the attestation was made.
- origin_to_address: The contract (to) address of the transaction where the attestation was made.
