As a Web3 Data Analyst, learning to manually decode event logs is crucial for assessing data accuracy, completeness, and consistency before diving into any analysis.
I've published this step-by-step guide to show you "How to Manually Decode Event Logs.

Using a simple Transfer event log, I explain learn how to:
- Use the keccak function to find the hash of topic0.
- Apply substring functions to extract the addresses of topic1 and topic2.
- Use the bytearray function to find the value in the data field.
The end result will be a well-decoded event log table that aligns with the Pickle table on @dune.eth
A huge thank you to @ilemi for helping me figure out how to execute this query on Dune.

Feel free to share your feedback and suggestions on future guides I can create to make our Web3 Data journey better.
Stay tuned for my next guide on Decoding Ethereum Traces...
