 ## Globally Unique Domain Zone
 
 For more information, see [here](../docs/globally-unique-domain-zone.md).

+## NNS and Frostfsid
+
+You can register a TLD domain without a committee signature using Frostfsid. To do this, create a new wallet
+```
+neo-go wallet init -w newwallet/wallet.json
+```
+
+Get wallet address:
+```
+neo-go wallet dump-keys -w newwallet/wallet.json
+[subject-address]
+[subject-key]
+```
+
+Create a subject in `FrostfsID`:
+```
+frostfs-adm morph frostfsid create-subject --subject-key="[subject-key]"
+```
+
+Grant permissions to the wallet:
+```
+frostfs-adm morph nns give-privilege --subject-address="[subject-address]"
