#302·set the Shell storage to the Statemine genesis

Motion 302 is up for vote!

The proposal is the first out of two motions that will be up for vote aiming to upgrade the Kusama Shell to Statemine: the first common good chain on Kusama.

This motion sets the Shell storage to the Statemine genesis. In order to do this, we need to make an XCM call to Shell that wraps a setStorage call.

This first motion will set some genesis storage items needed for Statemine. A second motion will authorize the runtime upgrade with a given code hash. The actual runtime code (matching the previously approved code hash) will then be submitted to Shell in an unsigned transaction after the authorization message.

The first message to Shell will be to store some items in state. The DATA for the system.setStorage can be found below (follow the steps):

Preimage hash for xcmPallet.send: 0xcf73c42d402fc5508a196e62d846b3aab7f7e70abde3f219cc4400d5b32e6701 - Preimage proof can be found HERE

Items in Storage can be verified HERE.

Please vote at your earliest convenience!

Steps to verify the preimage

STEP 1:

• Download genesis values from THIS LINK
• Open the PolkadotJS UI
• Fill up the information as shown HERE.
  Check that you get the same encoded call hash. We will need the encoded call data for step 2. Note that we do not need to submit this Transaction.

STEP 2:

• Verify the call data used on the xcmPallet.send call by using the Extrinsics tab on Polkadot js Apps.

NOTE: requireWeightAtMost is set to 100000000000 (100_000_000_000)

If your call data hash matches the one on the screenshot, the motion hash should be the same as the Preimage hash for xcmPallet.send above: 0xcf73c42d402fc5508a196e62d846b3aab7f7e70abde3f219cc4400d5b32e6701
