This proposal aims to Accept/Open an HRMP channel with Zeitgeist and register xcZTG.

XCM Disclosure: Zeitgeist Network

Summary

We propose to open a bi-directional channel between Moonbeam and Zeitgeist and to register Zeitgeist’s native currency ZTG as xcZTG. Initially, the main use case will be to transfer ZTG between the two chains to create a trade pair in Stellarswap and offer it to any dApp on Moonbeam that wants to utilize it. Another potential use-case of the channel is to offer prediction markets and the Futarchy governance mechanism in the near future to Moonbeam and any dApp on Moonbeam. Further use cases shall be evaluated over the course of time.
