This is a referendum to introduce an external proposal to initiate opening an outgoing HRMP channel to Moonbeam.
Technical Background
The batch transaction of the proposal consists of one sub transaction, which is a call to <code>polkadotXcm.send</code>. The message argument of <code>polkadotXcm.send</code> is complex but most of it just revolves around setting the payment for the transaction fee on the relay chain to open the HRMP channel.
The actual payload of this message is inside the third component and it is <code>0x3c00d4070000e803000000900100</code>.
Decoding this payloads (which is an extrinsic itself on the relay chain) will yield:
<ul>
<li>hrmp.hrmpInitOpenChannel with recipient 2004 (see <a href="https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc.dotters.network%2Fpolkadot#/extrinsics/decode/0x3c00d4070000e803000000900100">here</a>)</li>

This is a referendum to introduce an external proposal to initiate opening an outgoing HRMP channel to Moonbeam.

**Technical Background**

The batch transaction of the proposal consists of one sub transaction, which is a call to `polkadotXcm.send`. The message argument of `polkadotXcm.send` is complex but most of it just revolves around setting the payment for the transaction fee on the relay chain to open the HRMP channel.

The actual payload of this message is inside the third component and it is `0x3c00d4070000e803000000900100`.

Decoding this payloads (which is an extrinsic itself on the relay chain) will yield:

*   hrmp.hrmpInitOpenChannel with recipient 2004 (see [here](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc.dotters.network%2Fpolkadot#/extrinsics/decode/0x3c00d4070000e803000000900100))

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 except `None`.

- `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 the calls are dispatched 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>

- Problem Statement: The referendum aims to introduce an external proposal to open an outgoing HRMP channel to Moonbeam, targeting the Polkadot community and developers.
- Significance: The proposal is significant as it involves a technical adjustment to the Polkadot network, specifically the batch transaction of the proposal which includes a call to 'polkadotXcm.send'.
- Proposed Solution: The solution involves setting the payment for the transaction fee on the relay chain to open the HRMP channel. The actual payload of this message is '0x3c00d4070000e803000000900100', which when decoded, yields 'hrmp.hrmpInitOpenChannel' with recipient 2004.
- Expected Outcomes: The expected outcome is the successful opening of an outgoing HRMP channel to Moonbeam, enhancing the functionality and interoperability of the Polkadot network.
