 #
+#   gas_limit = <gas>
+#
+#       The gas limit is the maximum amount of gas that can be

+#       transactions from consuming too many resources.
+#
+#       If this parameter is unspecified, xrpld will use an internal

+#           gas_limit = 1000000      # 1 million gas
+#
+#   bytecode_size_limit = <bytes>
+#
+#       The bytecode size limit is the maximum size of a WASM extension in
+#       bytes. The size limit is used to prevent extensions from consuming

+#   gas_price = <micro-drops>
+#
+#       The gas price is the conversion between WASM gas and its price in drops.
