+# Hybrid Client
+
+This package provides a hybrid client implementation that maintains compatibility between Cosmos SDK v47 and v50 event handling.
+
+## Background
+
+In Cosmos SDK v50, there were significant changes to block event handling:
+- `BeginBlockEvents` and `EndBlockEvents` were deprecated
+- A new event type `FinalizeBlockEvents` was introduced to replace them
+
+This hybrid client seamlessly handles both versions by:
+- Supporting the legacy `BeginBlockEvents` and `EndBlockEvents` for v47 compatibility
+- Supporting the new `FinalizeBlockEvents` for v50 compatibility
+- Aggregating all events into `FinalizeBlockEvents` for consistent downstream handling
+
+This allows applications to work with both v47 and v50 chains without needing version-specific event handling logic.
