Support XCM complex asset transfers #4182

Closed acatangiu closed 2 months ago

acatangiu commented 6 months ago

Is there an existing issue?

[X] I have searched the existing issues

Experiencing problems? Have you tried our Stack Exchange first?

[X] This is not a support question.

Motivation

The currently existing instructions are too opinionated and force each XCM asset transfer to a single transfer type (teleport, local-reserve, destination-reserve). This results in inability to combine different types of transfers in single transfer which results in overall poor UX when trying to move assets across chains.

Request

Create a proof of concept for https://github.com/paritytech/xcm-format/pull/54

Solution

[ ] Implement https://github.com/paritytech/xcm-format/pull/54
[ ] Integrate with pallet-xcm
[ ] add complex asset transfer tests

Are you willing to help with this request?

Yes!

I created a proof-of-concept implementation and a proof-of-concept asset transfer test, transferring 2 different types of assets across 3 chains.
