Transfer assets from the local chain to the destination chain using explicit transfer types for assets and fees.
assets
must have same reserve location or may be teleportable to dest
. Caller must
provide the assets_transfer_type
to be used for assets
:
TransferType::LocalReserve
: transfer assets to sovereign account of destination chain and forward a notification XCM todest
to mint and deposit reserve-based assets tobeneficiary
.TransferType::DestinationReserve
: burn local assets and forward a notification todest
chain to withdraw the reserve assets from this chain’s sovereign account and deposit them tobeneficiary
.TransferType::RemoteReserve(reserve)
: burn local assets, forward XCM toreserve
chain to move reserves from this chain’s SA todest
chain’s SA, and forward another XCM todest
to mint and deposit reserve-based assets tobeneficiary
. Typically the remotereserve
is Asset Hub.TransferType::Teleport
: burn local assets and forward XCM todest
chain to mint/teleport assets and deposit them tobeneficiary
.
On the destination chain, as well as any intermediary hops, BuyExecution
is used to
buy execution using transferred assets
identified by remote_fees_id
.
Make sure enough of the specified remote_fees_id
asset is included in the given list
of assets
. remote_fees_id
should be enough to pay for weight_limit
. If more weight
is needed than weight_limit
, then the operation will fail and the sent assets may be
at risk.
remote_fees_id
may use different transfer type than rest of assets
and can be
specified through fees_transfer_type
.
The caller needs to specify what should happen to the transferred assets once they reach
the dest
chain. This is done through the custom_xcm_on_dest
parameter, which
contains the instructions to execute on dest
as a final step.
This is usually as simple as:
Xcm(vec![DepositAsset { assets: Wild(AllCounted(assets.len())), beneficiary }])
,
but could be something more exotic like sending the assets
even further.
origin
: Must be capable of withdrawing theassets
and executing XCM.dest
: Destination context for the assets. Will typically be[Parent, Parachain(..)]
to send from parachain to parachain, or[Parachain(..)]
to send from relay to parachain, or(parents: 2, (GlobalConsensus(..), ..))
to send from parachain across a bridge to another ecosystem destination.assets
: The assets to be withdrawn. This should include the assets used to pay the fee on thedest
(and possibly reserve) chains.assets_transfer_type
: The XCMTransferType
used to transfer theassets
.remote_fees_id
: One of the includedassets
to be used to pay fees.fees_transfer_type
: The XCMTransferType
used to transfer thefees
assets.custom_xcm_on_dest
: The XCM to be executed ondest
chain as the last step of the transfer, which also determines what happens to the assets on the destination chain.weight_limit
: The remote-side weight limit, if any, for the XCM fee purchase.

pub fn report_outcome_notify( message: &mut Xcm<()>, responder: impl Into<Location>, notify: impl Into<<T as Config>::RuntimeCall>, timeout: BlockNumberFor<T>, ) -> Result<(), XcmError>
Consume message
and return another which is equivalent to it except that it reports
back the outcome and dispatches notify
on this chain.
message
: The message whose outcome should be reported.responder
: The origin from which a response should be expected.notify
: A dispatchable function which will be called once the outcome ofmessage
is known. It may be a dispatchable in any pallet of the local chain, but other than the usual origin, it must accept exactly two arguments:query_id: QueryId
andoutcome: Response
, and in that order. It should expect that the origin isOrigin::Response
and will contain the responder’s location.timeout
: The block number after which it is permissible fornotify
not to be called even if a response is received.
report_outcome_notify
may return an error if the responder
is not invertible.
It is assumed that the querier of the response will be Here
.
NOTE: notify
gets called as part of handling an incoming message, so it should be
lightweight. Its weight is estimated during this function and stored ready for
weighing ReportOutcome
on the way back. If it turns out to be heavier once it returns
then reporting the outcome will fail. Futhermore if the estimate is too high, then it
may be put in the overweight queue and need to be manually executed.

Attempt to create a new query ID and register it as a query that is yet to respond, and which will call a dispatchable when a response happens.
sourcepub fn do_try_state() -> Result<(), TryRuntimeError>
pub fn do_try_state() -> Result<(), TryRuntimeError>
Ensure the correctness of the state of this pallet.
This should be valid before and after each state transition of this pallet.

fn start( dest: &Location, query_id: QueryId, max_weight: Weight, _context: &XcmContext, ) -> XcmResult
Start notifying location
should the XCM version of this chain change.
When it does, this type should ensure a QueryResponse
message is sent with the given
query_id

and with a response
of Response::Version
. This should happen
until/unless stop
is called with the correct query_id

If the location

error should be returned.
