The Xindi weapon was a massive, mobile particle beam weapon designed to destroy entire planets. There were actually three weapons built while the design was refined.
The weapons were built by the five Xindi species in cooperation, at the instigation of the Sphere Builders, who had informed the Xindi that Humans would be responsible for the destruction of the future Xindi homeworld in the 26th century. The weapon's primary goal was the destruction of Earth.
Certain steps were taken to prevent any one species from controlling the weapon. The final version required activation codes from at least three of the five species in order to function. However, it could be fired instantly if all five codes were used. It could not be armed while the propulsion system was online.
The weapon was designed primarily by Degra, a Xindi-Primate scientist and member of the Xindi Council, and constructed by the Aquatics. Most of the weapon's components were built by the Xindi, but at least one component came from the year 2573, supplied to the Xindi by the Sphere Builders. Another key component of the weapon was the mineral kemocite, which was provided by Gralik Durr's refining facility.
