Interpret XCM

[joepetrowski]

The parachain should support sending and receiving assets to/from other parachains.

XCM Revamp tracking issue:
paritytech/polkadot#2841

[apopiak]

We'll need to upgrade Polkadot to paritytech/polkadot#2896 and Cumulus to paritytech/cumulus#407

just a question for me to understand:
sending and receiving assets to/from other parachains, will likely be supported using the Xcm::WithDraw and Xcm::Deposit variants? That would mean the AssetTransactor and IsReserve types of the XcmConfig will make use of the assets pallet somehow (conversion of MultiAsset::ConcreteFungible -> AssetId), but are currently only configured to allow the relay chain to withdraw/deposit/teleport ROC right?

[joepetrowski]

Correct, as configured now it teleports ROC between Statemint and the Relay Chain. @riusricardo should know know more about how to send cross-chain asset messages.

@riusricardo Would you be so kind as to briefly shed some light on whether my assumptions are correct?
