subsquid / squid-astar-example

Small project showcasing the capabilities of the Subsquid SDK. Extracts EVM transactions on Astar and saves into a CSV file

squid-template

This is a sample squid project to demonstrate its structure and conventions. It tracks all Ethereum.transact calls on Astar and extracts basic information:

• from address
• to address
• Tx input
• Tx hash
• Method sighash (first four bytes of the Tx input)
• Value (if it was one of ERC20 approve, transfer or transferFrom)

The results are saved into a assets/astar-transactions.csv and can later be analyzed by tools such as DuckDB.

For more info consult the docs.
