A Tayden is the basic monetary unit of currency that is used by the aliens in Undertown and the known universe.
A tayden is a small piece of Taydenite that is shaped like a gemstone and has a symbol on it.
It has not yet been specified as to how much a tayden is worth, though its value is significant, being made of Taydenite.
In Special Delivery, Ben received varying amounts of taydens for his deliveries.
In Universe vs. Tennyson, apparently the fine for re-creating the Universe is 5 taydens.
