+## Use a custom native token
+
+Open the deploy_parameters.json file and add a new entry:
+
+```json
+{
+    "":"",
+    "":"",
+    "maxPriorityFeePerGas":"",
+    "multiplierGas": ""
+    "gasTokenAddress": "<TOKEN-ADDRESS>"
+}
+```
+
+`TOKEN-ADDRESS` is the address of a deployed ERC20 L1 token.
+
+If you leave the value empty, the ETH token address is used as default.
