Astar Network

I propose Astar open XCM channels with the following parachains:
Centrifuge, Crust, EnergyWebX, Kilt, Mythos, Neuroweb (formerly Origin Trail), Polimec, Robonomics, Subsocial, Zeitgeist. Summary: I&rsquo;ve seen two problems that I&rsquo;d like to solve.
<ul>
<li>Several OG chains STILL only have one or two XCM channels open</li>
<li>I hear some users ask when their favorite parachain token will be available on a DEX and the answer is &ldquo;once the team opens an XCM channel&rdquo;.</li>
</ul>
For some of smaller parachain teams, I&rsquo;m sure that they&rsquo;re focused on building their core product and maybe just haven&rsquo;t gotten around to slowly working through the three step process of opening up an XCM channel with each additional parachain. Therefore I&rsquo;m trying to get over that friction by opening lots of channels with trusted teams to increase the connectedness between Polkadot parachains. This will open up additional DeFi opportunities, possible team integrations, and most importantly removing one of the technical barriers that is hampering normal users.
For Astar, the most immediate benefit is the ability to trade additional parachain tokens within Astar DeFi. Astar dApps like Arthswap, Algem, SiO2, and Starlay could then offer swaps and lending for the parachain tokens.

Proposal
I propose Astar open bidirectional XCM channels with the following parachains: Centrifuge, Crust, EnergyWebX, Kilt, Mythos, Neuroweb, Polimec, Robonomics, Subsocial, Zeitgeist. If accepted, this will require execution of several batched extrinsics which I will submit for review at each stage.
Notes:
<ul>
<li>Robonomics just won their Polkadot slot and to my knowledge hasn&rsquo;t launched yet. But it&rsquo;s ok to go ahead and initiate channel opening with the relaychain so that Robonomics can accept when ready.</li>
</ul>
&nbsp;
Technical details
The general procedure for opening each XCM channel is as follows:
<ol>
<li>Astar initializes a proposal to open an Astar &rarr; ParachainB HRMP channel.</li>
<li>Parachain B governance accepts the incoming Astar HRMP channel request and initiates a request to open a return HRMP channel from Parachain B &rarr; Astar. In the same referendum, register ASTR on the chain (if they have a suitable pallet like assetRegistry integrated).</li>
<li>Astar accepts the incoming return channel and registers Parachain B&rsquo;s token.</li>
</ol>
For Zeitgeist, we will likely execute this process in reverse order because I have already submitted a ZTG governance proposal which includes initiating a channel with Astar: Initiate opening 16 XCM channels to other active parachains. Therefore Astar would start with Step 2 of accepting the incoming channel, registering ZTG, and initiating a return channel to Zeitgeist.
Note that I have already executed similar proposals on Interlay and Bifrost to open an additional 10 and 12 channels. As all of these init/open requests accumulate from the DeFi chains to the non-DeFi chains, I&rsquo;m hoping that I&rsquo;ll be able to batch the channel acceptances and asset registrations on each of the destination chains, to minimize how many governance proposals (and voter fatigue) are required.

- **Problem Statement:** 
  - Several Polkadot parachains have limited XCM channels, hindering DeFi opportunities and user accessibility.

- **Significance:** 
  - Opening bidirectional XCM channels with trusted parachains will enhance DeFi opportunities, team integrations, and user accessibility within the Polkadot ecosystem.

- **Proposed Solution:** 
  - Astar will open bidirectional XCM channels with Centrifuge, Crust, EnergyWebX, Kilt, Mythos, Neuroweb, Polimec, Robonomics, Subsocial, and Zeitgeist to increase connectedness between parachains.

- **Expected Outcomes:** 
  - Increased DeFi opportunities, enhanced user accessibility, and the ability to trade additional parachain tokens within Astar's DeFi ecosystem.
