Summary:
Proposal to open a bi-directional channel between Shiden Network and GMorDIE. The primary use cases will be allow our community of builders to propose different proofs of concepts, ideate and implement novel builds between both chains.

Technical details:
The procedure for opening the channels is as follows:

• Shiden proposes to open the Shiden to GMorDIE HRMP channel
• Wait until the proposal on Step 1 gets approved & enacted.
• GMorDIE accepts the Shiden to GMorDIE HRMP channel, requests opening of the GMorDIE to Shiden HRMP channel and adds SDN to its asset registry.
• Wait until the proposal on Step 3 gets approved & enacted.
• Shiden proposes to accept GMorDIE to Shiden HRMP channel.
• Wait for another session on Kusama for the change to be effective.
• These extrinsics need to be called with the parachain’s sovereign account as the origin. To achieve this, on the GMorDIE side we will use polkadot-xcm pallet to send XCM message to the relay chain, by executing the following extrinsic from the parachain.

As a prerequisite, the parachain’s sovereign account must contain at least 10 KSM to be locked as collateral (5 for each channel direction), plus some KSM to pay for XCM execution fees.
