TL:DR

We propose to update Moonriver's XCM Supported Version on Kusama to Version 2.

Summary

Kusama is using XCM Version 1 when "communicating" with Moonriver. This proposal updates the XCM Supported version to Version 2.

Proposal

Proposal #17 with the following hash: 0x1fbe2211015409a8a4ab90235a19436e63690e333356e965f3f842389bb1ef31

Technical details:

Kusama expects from Moonriver a response to a Query ID with the supported verison. The Query ID can be verified by checking the chain state xcmPallet.queries(2654), which returns the following:

{
  VersionNotifier: {
    origin: {
      V1: {
        parents: 0
        interior: {
          X1: {
            Parachain: 2,023
          }
        }
      }
    }
    isActive: false
  }
}

The version is updated by sending a XCM message with the QueryResponse XCM instruction, queryId of 2654, response set to Version: 2 and maxWeight to 0.

If you are interested, the hex-encoded call data is Moonriver is: 0x67000101000204037929030200000000
