Open XCM channel with HydrDX - Part 1/1 (Accept & request HRMP)

This proposal opens the XCM channel to HydraDX. This will allow assets to be transferred in between Interlay and HydraDX and open a path towards more use cases for iBTC and more collateral assets for iBTC.

TC Table

Since we want to proceed as quickly as possible with opening the channel to move the discussion to actual use cases for both communities, we request that this proposal be tabled.
