Hi All I am currently embarking on trying to send funds from the treasury via XCM
I am fairly certain this isn't possible right now because the treasury origin does not have send rights. I am currently working on a pr to make this possible
What I am trying to do is a reserve asset transfer, but that requires a signed origin and hence I am not sure it can be done via governance
As an alternative, I am trying to split it in 2 parts
batch {
spend(ParachainSovereignAccount),
// Notify destination of funds sent
send(dest: para, xcm: [ReserveAssetDeposited, ..])
}
However, unless I am mistaken, ReserveAssetDeposited must be executed and not sent.
If I use DepositAssets instead the message gets sent but there are no assets in holding so AssetTransactor does not deposit the asset. See here
Even a simple message below fails
let assets = MultiAssets::from(vec![MultiAsset {
id: Concrete(MultiLocation {
parents: 0,
interior: Here,
}),
fun: Fungible(transfer_amount),
}]);
let msg = VersionedXcm::from(Xcm(vec![
UnpaidExecution {
weight_limit: WeightLimit::Unlimited,
check_origin: None,
},
ReserveAssetDeposited(assets.clone().into()),
]));
I get the below error from the logs

So tldr; can I send Sep 06 10:43:08.280 TRACE xcm::execute_xcm_in_credit: Execution errored at 2: UntrustedReserveLocation (original_origin: MultiLocation { parents: 1, interior: Here }) which I think is because again this is not coming from the chain but rather through a gov body
I do wonder if DescendOrigin can help but unfortunately, I cannot find documentation around that
