I sought to find xcm extrinsics sent from the moonriver/moonbeam parachains but it seems to do things a little differently. Where can I find the sent message or at least the message hash so that I can correlate it with the UMP message id that I can see on the relay chain?

Are the messages inside the ethereum.Executed extrinsic? Would decoding the eth.Log events show some of this? Is there a good moonscan link that can show some of this decoded?

With kind regards,

Currently the ump queue does not show an event with the message hash. We aim at solving that in this PR: https://github.com/paritytech/cumulus/pull/1228. Right now there is no clear way to correlate for any chain using the xtokens or the pallet-xcm pallets, since non of them (except for the send extrinsic in pallet-xcm), since none of them (at least that I know of) deposit an event with the message nor the messageId

    Excellent news. Much appreciated that you're making it easier for cross-chain explorers to show what's going on.
