+# `x/rootupdater`
+
+## Abstract
+
+This module is designed to extract the passport root from Ethereum Virtual Machine (EVM) contract events and 
+subsequently create a new operation for `rarimo-core` module .
+
+----
+
+## Concepts
+
+The core functionality of this module involves monitoring and processing events emitted by EVM contracts
+to capture the passport root. Once the passport root is accurately extracted, the module proceeds to create
+a new operation within the rarimo-core module.
+
+An operation includes the following fields, such as `contract_address`, `root`, `root_timestamp`, `block_height` 
+
+## State
+
+Model can be found in `proto/rootupdater`. Module data are stored inside Params
+
+####  Module params proto
+
+```protobuf
+message Params {
+  string contract_address = 1;
+  string root = 2;
+  string last_signed_root = 3;
+  string last_signed_root_index = 4;
+  string event_name = 5;
+  int64 root_timestamp = 6;
+  uint64 block_height = 7;
+}
+```
+
+Example values are provided in JSON for convenient reading.
+
