**Note: PLEASE REJECT - The proposal will fail because it does not provide enough weight. A new proposal will be submitted for vote.**

Five more parachains have requested an HRMP channel with Statemint. This motion accepts them all and opens return channels.

**Handy Info**

- **Parachains that aim to open channels**: 2021, 2031, 2032, 2035, 2046.

**Call Construction**

These are constructed backwards. That is, the call to use as the proposal is at the end.

**Relay Chain Call to Execute**

First, we need the call that Statemint will execute on the Relay Chain. This accepts all channel requests and returns channel requests to the initiators.

- Encoded Call Data (Polkadot): 

```
0x1a02283c01e50700003c01ef0700003c01f00700003c01f30700003c01fe0700003c00e5070000e8030000009001003c00ef070000e8030000009001003c00f0070000e8030000009001003c00f3070000e8030000009001003c00fe070000e803000000900100
```

**Message from Statemint**

The above message needs to come from Statemint. So we put it into an XCM (the “Transact” instruction) along with purchasing some execution capacity and returning any leftover fees to the Treasury.

```

**Proposal on the Relay Chain**

But, governance is on the Relay Chain, not Statemint. So take some DOT from the Treasury (100 DOT for 10 channels at 10 DOT each plus 2 DOT for fees) and send a message to Statemint telling it to send a message back. This is the proposal to vote on.

Preimage has already been submitted for verification by the community as well. After/if Council votes and passes this proposal, this will need to be voted by the community in referenda queue. 

Schedule a majority-carries referendum to be tabled next once it is legal to schedule
an external referendum.

The dispatch of this call must be `ExternalMajorityOrigin`.

- `proposal_hash`: The preimage hash of the proposal.

Unlike `external_propose`, blacklisting has no effect on this and it may replace a
pre-scheduled `external_propose` call.

Weight: `O(1)`

Send a batch of dispatch calls and atomically execute them.
The whole transaction will rollback and fail if any of the calls failed.

May be called from any origin.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then call are dispatch without checking origin filter. (This includes
bypassing `frame_system::Config::BaseCallFilter`).

# <weight>
- Complexity: O(C) where C is the number of calls to be batched.
# </weight>
