[[Polkadex] XCM Disclosures
](https://forum.moonbeam.network/t/xcm-disclosure-polkadex/888)

### **TL:DR**

This is a batched proposal to Accept/Open an HRMP channel with the Polkadex parachain and Register Asset xcPDEX on Moonbeam.

### **Summary**

We propose to open a bi-directional channel between Moonbeam and the Polkadex parachain. Initially, this channel would allow the back and forth transfers of GLMR and PDEX between the two parachains. The opening of a bidirectional channel will ultimately allow Moonbeam assets like GLMR (and other Moonbeam-native assets) to be traded on Polkadex Orderbook, Polkadex’s non-custodial, order-book-based exchange.
With a potential Polkadex Orderbook listing, GLMR would first be paired with USDT and, gradually, with other DotSama assets as more channels are open between Polkadex and additional parachains; thus creating efficient and liquid trading pairs, which, in turn, will make non-custodial trading of GLMR and other DotSama assets free, easy, and fast.
In addition, we propose that the xcPDEX asset be registered on Moonbeam, thus adding support for PDEX across the Moonbeam ecosystem and enabling the use of PDEX in dApps on Moonbeam.

### **Token Metadata**

Multilocation: {parents: 1, interior: {x1:{parachain: 2040}}}
Decimals: 12
Name: Polkadex

### **On-Chain Proposal Reference**

On-Chain Proposal #[30] with the associated hash: 0xa7a88a20a6a4fa2ae5155c5cc32d8e725202e7f1691d65ca04e1b609ca362186

### **Technical details:**

The procedure for opening the channels is as follows:

1. Already sent a request to open a channel between Polkadex Parachain <> Moonbeam
2. Registered Moonbeam asset on both Polkadex Parachain and Solochain.
3. Generated an encoded batch call for the following transactions (which will be executed on Moonbeam):
- Open HRMP Channel between Moonbeam Parachain <> Polkadex Parachain
- Accept HRMP request from Polkadex Parachain.
- Create xcPDEX token on Moonbeam Parachain.

[Referendum: 30] Polkadex Proposal Open/Accept HRMP channel and Register Asset xcPDEX

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`).

## Complexity
- O(C) where C is the number of calls to be batched.

- Problem Statement: The current lack of a bi-directional channel between Moonbeam and the Polkadex parachain limits the transfer and trading of assets between the two platforms. The intended audience includes users and developers of Moonbeam and Polkadex.
- Significance: The absence of this channel restricts the liquidity and efficiency of trading pairs, hindering non-custodial trading of GLMR and other DotSama assets.
- Proposed Solution: The proposal suggests opening a bi-directional channel between Moonbeam and Polkadex, allowing back and forth transfers of GLMR and PDEX. It also proposes registering the xcPDEX asset on Moonbeam to support PDEX across the Moonbeam ecosystem.
- Expected Outcomes: The opening of this channel will enable Moonbeam assets to be traded on Polkadex Orderbook, creating efficient and liquid trading pairs. This will facilitate free, easy, and fast non-custodial trading of GLMR and other DotSama assets. Registering xcPDEX on Moonbeam will enable the use of PDEX in dApps on Moonbeam.
