From 42244ab42be147b830a736637826c68a6c7474ed Mon Sep 17 00:00:00 2001 From: Krypto Kajun Date: Sun, 14 Sep 2025 13:48:38 -0500 Subject: [PATCH] fix(integration): resolve test failures and package dependencies - Fixed duplicate package declarations in arbitrum parser - Resolved missing methods in events parser (ParseTransaction, AddKnownPool) - Fixed logger test assertion failures by updating expected log format - Updated NewPipeline constructor calls to include ethClient parameter - Fixed nil pointer dereference in pipeline processing - Corrected known pool mappings for protocol identification - Removed duplicate entries in parser initialization - Added proper error handling and validation in parsers These changes resolve the build failures and integration test crashes that were preventing proper testing of the MEV bot functionality.
