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

[Polkadex] XCM Disclosures


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


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.
