-Accounts staked for less than the defined minimum staking period are not eligible to earn rewards for that period. Nodes and accounts accumulate stake and rewards per whole HBAR. Fractions are rounded down. When a node is deleted, it returns zero rewards.

BATCH_LIST_EMPTY | 388 | Submitting a batch with no inner transactions | Add at least one inner transaction to the batch |

BATCH_KEY_SET_ON_NON_INNER_TRANSACTION | 393 | `BatchKey` is set on the outer transaction | Only set BatchKey on inner transactions, not on the outer batch transaction |
INVALID_BATCH_KEY | 394 | The `BatchKey` is missing or invalid | Ensure all inner transactions have a valid `BatchKey` set |
INVALID_NODE_ACCOUNT_ID | 341 | Inner transaction has a nodeAccountID other than 0.0.0 | Use the batchify() method which automatically sets nodeAccountID to 0.0.0 |

+### Example 1: Fee Collection in Action (Crypto Transfer)
+
+Let's look at a standard `CRYPTO TRANSFER` transaction to see how the fee is collected.
+
+**Transaction Link:** [https://hashscan.io/mainnet/transaction/1771485699.125401461](https://hashscan.io/mainnet/transaction/1771485699.125401461)
+
+In this transaction, account `0.0.10231006` sends a small amount of HBAR to `0.0.37`. The HBAR transfers clearly show the fee consolidation:
+
+| Account | Amount | Description |
+| :--- | :--- | :--- |
+| `0.0.10231006` | **-0.00102456ℏ** | Payer (Sent transfer + fee) |
+| `0.0.37` | **+0.00000009ℏ** | Receiver (Node 34) |
+| **`0.0.802`** | **+0.00102447ℏ** | **Fee Collection Account** |
+
+
+### Example 2: Fee Collection Across All Transaction Types
+
+The HIP-1259 fee collection mechanism applies to all transaction types, not just crypto transfers. Let's look at a `SUBMIT MESSAGE` transaction to see the same streamlined process.
+
+**Transaction Link:** [https://hashscan.io/mainnet/transaction/1771486013.122401000](https://hashscan.io/mainnet/transaction/1771486013.122401000)
+
+#### Transaction Details
+
+- **ID:** `0.0.85243@1771485974.183471116`
+- **Type:** `SUBMIT MESSAGE`
+- **Fee:** `0.00902194ℏ`
+
+#### HBAR Transfers Breakdown
+
+This transaction submitted a message to the Hedera Consensus Service. Notice how simple the HBAR transfers are:
+
+| Account | Amount | Description |
+| :--- | :--- | :--- |
+| `0.0.85243` | **-0.00902194ℏ** | Payer (Paid the transaction fee) |
+| **`0.0.802`** | **+0.00902194ℏ** | **Fee Collection Account** |
+
+That's it. The entire fee is cleanly transferred to account `0.0.802`. There are no other transfers related to the fee in this transaction, making the record simple and easy to understand.
