This will be a batch of two scheduled transactions. They would probably work fine at once, but will schedule to be safe and ensure that the `set_storage` takes place prior to authorizing the upgrade.

The first will set some storage keys in Shell for Statemint's "genesis". The second will authorize the upgrade to Statemint. Both calls need to be constructed on Shell and then dispatched from the Relay Chain in an XCM.

See the [release notes](https://github.com/paritytech/cumulus/releases/tag/statemint-v6.0.1) to review the assets, reproduce the `set_storage` call, and generate the runtime.

## Shell Constructions

### Set Storage

The `set_storage` call can be generated with the `build-spec` command from a collator node, using `statemint_genesis.json` as input. See the release notes for more info. Notable storage items include:

- Setting the first set of Aura collators.
- Setting the `SafeXcmVersion` to `2` to protect against older XCM formats.

### Authorize Upgrade

This message authorizes the upgrade of Shell to a runtime with a given hash (statemint_runtime-v601.compact.compressed.wasm). Once the upgrade is authorized, anyone can submit the runtime via `parachain_system.enact_authorized_upgrade`, and it will upgrade 600 blocks (approximately 1 hour) later.

Call data: `0x0103af49687b93d91fc08c1fcea1001d724a95c533a949019645d3e4179beedbf67e`

## Polkadot Proposal

This proposal is to schedule these messages to dispatch from Polkadot to Shell. They will dispatch 5 and 20 blocks after enactment to ensure each is processed separately. We give them plenty of weight (100 billion and 1 billion, respectively) to ensure they execute.

Call hash: `0xa6830793b6a3473f66fbd7305a9e330dd2dd688df0e8fcbd0c9ff08d28040a34`

- Problem Statement: The Polkassembly CouncilMotion post discusses the need for a safe and effective upgrade to Statemint, a common-good parachain, through two scheduled transactions. The intended audience is the Polkadot community, particularly those involved in the technical aspects of the network.
- Significance: The upgrade is crucial to ensure the smooth functioning of the Statemint parachain, which is a key component of the Polkadot ecosystem. The upgrade process involves setting storage keys and authorizing the upgrade, which requires careful planning and execution.
- Proposed Solution: The post proposes a two-step solution. The first step involves setting some storage keys in Shell for Statemint's "genesis". The second step authorizes the upgrade to Statemint. Both calls need to be constructed on Shell and then dispatched from the Relay Chain in an XCM. The post provides detailed instructions and call data for both steps.
- Expected Outcomes: The successful implementation of the proposed solution will result in a safe and effective upgrade to Statemint. This will ensure the continued smooth operation of the parachain, contributing to the overall stability and functionality of the Polkadot network.
