If someone of the Uzumaki Clan that can use Chakra Chains has access to Truth-Seeking Balls they can create the chains using them, the chains created this way are much more durable than the regular Chakra Chains, being completely immune to the effects of Ninjutsu, this jutsu is more likely than not the most powerful version of the Chakra Chains. It has the same applications as the Chakra Chains.
