+  This page provides info on making batch calls to our RPC nodes, enabling
+  efficient and simultaneous requests. Batch calling is useful for scenarios
+  requiring data from multiple blocks or transaction.
+---
+
+# Batch Calling
+
+## **Overview**
+
+Batch calling allows you to send multiple JSON-RPC requests in a single API call. This method is efficient for retrieving or sending data to multiple endpoints in one network request, streamlining your interactions with the blockchain.
+
+> Note : 
+>
+> 1. Batch Request is only available for enterprise users.
+> 2. This feature requires the use of the SDK with an API key. 
+> 3. All batch requests are processed as raw node requests.
+
+## Init Example via SDK
+
+For batch calling, you can use our SDK to simplify the process. Here's an example of initialising the SDK for batch requests:
+
+```javascript
+const { TatumSDK, Network } = require('@tatumio/tatum');
+
+const tatum = await TatumSDK.init({
+    network: Network.ETHEREUM, 
+    apiKey: { v4: 'YOUR-API-KEY'}
+    }
+)
+```
+
+## Batch Call Format
+
+A batch call is a JSON array containing multiple JSON-RPC request objects. Each object in the array is a separate request, following the standard JSON-RPC request format.
+
+## Preparing the request
+
+The rawBatchRpcCall function expects request as an array of request objects, where each request is a standard rpc request.
+
+```bash
+[{
+    "jsonrpc":"2.0",
+    "method":"METHOD_NAME",
+    "params":[PARAMS],
+    "id":1
+}, {
+    // Additional request
+}]'
+```
+
+## Making the Batch Request : 
+
+```javascript
+const { TatumSDK, Network } = require('@tatumio/tatum');
+
+(async () => {
+const tatum = await TatumSDK.init({
+    network: Network.ETHEREUM, 
+    apiKey: { v4: 'YOUR-API-KEY'}
+    }
+)
+
+request = [{
+      "jsonrpc": "2.0",
+      "id": 1,
+      "method": "eth_blockNumber"
+    },
+    {
+      "jsonrpc": "2.0",
+      "id": 2,
+      "method": "eth_getBlockByNumber",
+      "params": [
+        "latest",
+        true
+        ]
+    }]
+  
+const batchRequest = await tatum.rpc.rawBatchRpcCall(request);
+console.log(batchRequest)
+
+})();
+```
+
+## Best Practices
+
+* Ensure that each request in the batch has a unique ID.
+* Verify the format and parameters of each request to avoid errors.
+* Consider the server load and rate limits when making batch calls.
