In some fanfics, Naruto's chakra chains could be a result of some ancient Uzumaki clan ability that he discovers. Maybe it was a hidden power within his bloodline all along, and through intense training or a particular encounter, he unlocks this ability to use the chakra chains.
One possible origin in fanfics could be that Naruto is exposed to a special type of chakra or energy source. This exposure mutates his own chakra in a way that allows him to form chakra chains. It could be something like a cursed object that he comes into contact with, but instead of being cursed, it gives him this new power.
Some fanfics might suggest that Naruto's chakra chains are a gift from a powerful being. For example, a sage or a spirit could bestow this ability upon him as a means to help him in his battles against stronger foes. Another origin could be that Naruto studies some long - forgotten scrolls that detail the creation and use of chakra chains, and he manages to master this technique on his own through his determination and hard work.
