Pull request overview
This PR optimizes the _get_last_event method in the ContractWrapper class by introducing concurrent batch processing of block ranges. The optimization changes from a sequential scan through block ranges to a concurrent batch-based approach that can fetch multiple chunks in parallel, significantly speeding up the operation when events are sparse or located in older blocks.
Changes:
- Added
itertoolsimport to support batch processing - Refactored
_get_last_eventto build all chunk ranges upfront and process them in concurrent batches - Introduced a nested
fetch_chunkasync function to encapsulate the event fetching logic
