+# UpdateBatchInfo
+Follow the steps below.
+### Step 1. Register the key for the new batch submitter address.
+`opinitd keys add mocha-4 batch --bech32=celestia`
+
+*Make sure that this new account has a sufficient balance.*
+
+### Step 2.	Run the Update batch info command. 
+`opinitd tx update-batch-info CELESTIA celestia...`
+
+The proposer sends a transaction that includes an update batch info message with the new `ChainType` and `SubmitterAddress`. The bot will `shut down` when it encounters the `MsgUpdateBatchInfo`.
+
+### Step 3. Update the DA node config in the executor config.
+```json
+{
+...
+  "da_node": {
+    "chain_id": "mocha-4",
+    "bech32_prefix": "celestia",
+    "rpc_address": "",
+    "gas_price": "",
+    "gas_adjustment": 1.5,
+    "tx_timeout": 60
+  }
+}
+```
+
+### Step 4. Start the OPInit bot.
