From f600b7b15ef091d289835f415823e83e2947b431 Mon Sep 17 00:00:00 2001 From: defiQUG Date: Wed, 5 Nov 2025 16:28:48 -0800 Subject: [PATCH] Add ECDSA signature verification and enhance ComboHandler functionality - Integrated ECDSA for signature verification in ComboHandler. - Updated event emissions to include additional parameters for better tracking. - Improved gas tracking during execution of combo plans. - Enhanced database interactions for storing and retrieving plans, including conflict resolution and status updates. - Added new dependencies for security and database management in orchestrator. --- Dockerfile | 39 +++ contracts/ComboHandler.sol | 82 +++-- contracts/MultiSigWallet.sol | 129 ++++++++ contracts/TimelockController.sol | 18 ++ contracts/scripts/deploy.ts | 40 +++
