+# MaxAttemptsError
+
+## Overview
+
+`MaxAttemptsError` is an exception that occurs when the SDK has exhausted all retry attempts to communicate with a Hedera network node. This error represents transient network issues or node unavailability rather than transaction logic errors.
+
+## When It Occurs
+
+`MaxAttemptsError` is raised when:
+- A node repeatedly fails to respond to requests
+- Network connectivity issues prevent communication with a node
+- The node is temporarily unavailable or overloaded
+- Multiple retry attempts have all failed
+
+## Error Attributes
+
+The `MaxAttemptsError` exception provides the following attributes:
+
+- **`message`** (str): The error message explaining why the maximum attempts were reached
+- **`node_id`** (str): The ID of the node that was being contacted when the max attempts were reached
+- **`last_error`** (Exception): The last error that occurred during the final attempt
+
+## Error Handling Context
+
+Understanding the different stages of failure is crucial for proper error handling:
+
+1. **Precheck Errors** (`PrecheckError`): Failures before transaction submission (e.g., insufficient balance, invalid signature)
+2. **MaxAttemptsError**: Network/node retry failures during communication
+3. **Receipt Status Errors** (`ReceiptStatusError`): Failures after consensus (e.g., smart contract revert)
+
+Many developers assume that if `execute()` doesn't throw, the transaction succeeded. These exceptions explicitly show different stages of failure.
+
+## Example Usage
+
+```python
+from hiero_sdk_python import Client, TransferTransaction
+from hiero_sdk_python.exceptions import MaxAttemptsError, PrecheckError, ReceiptStatusError
+
+# Create client and transaction
+client = Client.forTestnet()
+transaction = TransferTransaction()
+    .addHbarTransfer(sender_account, -1000)
+    .addHbarTransfer(receiver_account, 1000)
+
+try:
+    # Execute the transaction
+    receipt = transaction.execute(client)
+    print("Transaction executed successfully")
+
+except PrecheckError as e:
+    # Handle precheck failures (before submission)
+    print(f"Precheck failed: {e.message}")
+    print(f"Status: {e.status}")
+
+except MaxAttemptsError as e:
+    # Handle network/node retry failures
+    print(f"Max attempts reached on node {e.node_id}: {e.message}")
+    if e.last_error:
+        print(f"Last error: {e.last_error}")
+
+    # Common recovery strategies:
+    # 1. Retry with a different node
+    # 2. Wait and retry the same node
+    # 3. Check network connectivity
+
+except ReceiptStatusError as e:
+    # Handle post-consensus failures
+    print(f"Transaction failed after consensus: {e.message}")
+    print(f"Status: {e.status}")
+```
+
+## Recovery Strategies
+
+When encountering a `MaxAttemptsError`, consider these approaches:
+
+### 1. Retry with Different Node
+```python
+try:
+    receipt = transaction.execute(client)
+except MaxAttemptsError as e:
+    # Switch to a different node and retry
+    client.setNetwork([{"node2.hedera.com:50211": "0.0.2"}])
+    receipt = transaction.execute(client)
+```
+
+### 2. Exponential Backoff
+```python
+import time
+
+def execute_with_retry(transaction, client, max_retries=3):
+    for attempt in range(max_retries):
+        try:
+            return transaction.execute(client)
+        except MaxAttemptsError as e:
+            if attempt == max_retries - 1:
+                raise
+            wait_time = 2 ** attempt  # 1, 2, 4 seconds
+            time.sleep(wait_time)
+```
+
+### 3. Node Health Check
+```python
+try:
+    receipt = transaction.execute(client)
+except MaxAttemptsError as e:
+    print(f"Node {e.node_id} appears unhealthy")
+    # Implement node health monitoring
+    # Consider removing the node from rotation temporarily
+```
+
+## Best Practices
+
+1. **Always catch MaxAttemptsError separately** from other exceptions to implement appropriate retry logic
+2. **Log the node_id** to identify problematic nodes in your network
+3. **Implement circuit breakers** to temporarily skip consistently failing nodes
+4. **Use exponential backoff** when retrying to avoid overwhelming the network
+5. **Monitor last_error** to understand the root cause of failures
