+# Milestone Delivery :mailbox:
+
+* **Application Document:** [https://github.com/w3f/Grants-Program/pull/2575]
+* **Milestone Number:** 1
+
+
+**Context** 
+Milestone 1 focuses on the development of the Core Simulation Engine for TxSim. This includes the initial backend logic required to simulate transactions on Moonbeam (EVM) and Astar (WASM). 
+We have also implemented the first version of our fee estimation module to help users understand weight-based costs before they sign transactions. This foundation allows for future risk detection and SDK integration.
+> Please provide a short paragraph or two connecting the deliverables in this milestone and describing their purpose.
