-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:

-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]"
