+# Contract Review Fixes Applied
+
+**Date**: 2025-12-11
+**Status**: Fixes Applied
+
+---
+
+## ✅ Fixes Applied
+
+### TransactionMirror.sol
+
+1. **✅ Added Batch Size Limit**
+   - Added `MAX_BATCH_SIZE = 100` constant
+   - Added validation: `require(txHashes.length <= MAX_BATCH_SIZE, "batch too large")`
+   - **Reason**: Prevents gas limit issues with large batches
+
+2. **✅ Added Empty Batch Check**
+   - Added validation: `require(txHashes.length > 0, "empty batch")`
+   - **Reason**: Prevents wasteful empty batch calls
+
+3. **✅ Simplified Block Range Calculation**
+   - Removed unnecessary length checks (already validated above)
+   - **Reason**: Code simplification
+
+---
+
+## 📋 Remaining Recommendations (Optional)
+
+### Medium Priority (Optional)
+- [ ] Add timestamp validation (prevent future/very old timestamps)
+- [ ] Add block number ordering validation (if sequential ordering required)
+
+### Low Priority (Optional)
+- [ ] Add query functions for filtered searches
+- [ ] Add data size limits
+- [ ] Add previous block hash to MainnetTether event
+
+---
+
+## ✅ Deployment Status
+
+**MainnetTether.sol**: ✅ Ready for deployment
+**TransactionMirror.sol**: ✅ Ready for deployment (fixes applied)
+
+Both contracts are now ready for Foundry deployment.
