# Note for reviewer Most changes are just syntax changes necessary for the new version. Most important files should be the ones under the `xcm` folder. # Description Added XCMv4. ## Removed `Multi` prefix The following types have been renamed: - MultiLocation -> Location - MultiAsset -> Asset - MultiAssets -> Assets - InteriorMultiLocation -> InteriorLocation - MultiAssetFilter -> AssetFilter - VersionedMultiAsset -> VersionedAsset - WildMultiAsset -> WildAsset - VersionedMultiLocation -> VersionedLocation In order to fix a name conflict, the `Assets` in `xcm-executor` were renamed to `HoldingAssets`, as they represent assets in holding. ## Removed `Abstract` asset id It was not being used anywhere and this simplifies the code. Now assets are just constructed as follows: ```rust let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into(); ``` No need for specifying `Concrete` anymore. ## Outcome is now a named fields struct Instead of ```rust pub enum Outcome { Complete(Weight), Incomplete(Weight, Error), Error(Error), } ``` we now have ```rust pub enum Outcome { Complete { used: Weight }, Incomplete { used: Weight, error: Error }, Error { error: Error }, } ``` ## Added Reanchorable trait Now both locations and assets implement this trait, making it easier to reanchor both. ## New syntax for building locations and junctions Now junctions are built using the following methods: ```rust let location = Location { parents: 1, interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into() }; ``` or ```rust let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]); ``` And they are matched like so: ```rust match location.unpack() { (1, [Parachain(id)]) => ... (0, Here) => ..., (1, [_]) => ..., } ``` This syntax is mandatory in v4, and has been also implemented for v2 and v3 for easier migration. This was needed to make all sizes smaller. # TODO - [x] Scaffold v4 - [x] Port github.com/paritytech/polkadot/pull/7236 - [x] Remove `Multi` prefix - [x] Remove `Abstract` asset id --------- Co-authored-by: command-bot <> Co-authored-by: Keith Yeung <[email protected]>

We currently use a bit of a hack in `.cargo/config` to make sure that clippy isn't too annoying by specifying the list of lints. There is now a stable way to define lints for a workspace. The only down side is that every crate seems to have to opt into this so there's a *few* files modified in this PR. Dependencies: - [x] PR that upgrades CI to use rust 1.74 is merged. --------- Co-authored-by: joe petrowski <[email protected]> Co-authored-by: Branislav Kontur <[email protected]> Co-authored-by: Liam Aharon <[email protected]>

## Summary This pull request proposes a solution for improved control of the versioned XCM flow over the bridge (across different consensus chains) and resolves the situation where the sending chain/consensus has already migrated to a higher XCM version than the receiving chain/consensus. ## Problem/Motivation The current flow over the bridge involves a transfer from AssetHubRococo (AHR) to BridgeHubRococo (BHR) to BridgeHubWestend (BHW) and finally to AssetHubWestend (AHW), beginning with a reserve-backed transfer on AHR. In this process: 1. AHR sends XCM `ExportMessage` through `XcmpQueue`, incorporating XCM version checks using the `WrapVersion` feature, influenced by `pallet_xcm::SupportedVersion` (managed by `pallet_xcm::force_xcm_version` or version discovery). 2. BHR handles the `ExportMessage` instruction, utilizing the latest XCM version. The `HaulBlobExporter` converts the inner XCM to [`VersionedXcm::from`](https://github.com/paritytech/polkadot-sdk/blob/63ac2471/polkadot/xcm/xcm-builder/src/universal_exports.rs#L465-L467), also using the latest XCM version. However, challenges arise: - Incompatibility when BHW uses a different version than BHR. For instance, if BHR migrates to **XCMv4** while BHW remains on **XCMv3**, BHR's `VersionedXcm::from` uses `VersionedXcm::V4` variant, causing encoding issues for BHW. ``` /// Just a simulation of possible error, which could happen on BHW /// (this code is based on actual master without XCMv4) let encoded = hex_literal::hex!("0400"); println!("{:?}", VersionedXcm::<()>::decode(&mut &encoded[..])); Err(Error { cause: None, desc: "Could not decode `VersionedXcm`, variant doesn't exist" }) ``` - Similar compatibility issues exist between AHR and AHW. ## Solution This pull request introduces the following solutions: 1. **New trait `CheckVersion`** - added to the `xcm` module and exposing `pallet_xcm::SupportedVersion`. This enhancement allows checking the actual XCM version for desired destinations outside of the `pallet_xcm` module. 2. **Version Check in `HaulBlobExporter`** uses `CheckVersion` to check known/configured destination versions, ensuring compatibility. For example, in the scenario mentioned, BHR can store the version `3` for BHW. If BHR is on XCMv4, it will attempt to downgrade the message to version `3` instead of using the latest version `4`. 3. **Version Check in `pallet-xcm-bridge-hub-router`** - this check ensures compatibility with the real destination's XCM version, preventing the unnecessary sending of messages to the local bridge hub if versions are incompatible. These additions aim to improve the control and compatibility of XCM flows over the bridge and addressing issues related to version mismatches. ## Possible alternative solution _(More investigation is needed, and at the very least, it should extend to XCMv4/5. If this proves to be a viable option, I can open an RFC for XCM.)._ Add the `XcmVersion` attribute to the `ExportMessage` so that the sending chain can determine, based on what is stored in `pallet_xcm::SupportedVersion`, the version the destination is using. This way, we may not need to handle the version in `HaulBlobExporter`. ``` ExportMessage { network: NetworkId, destination: InteriorMultiLocation, xcm: Xcm<()> destination_xcm_version: Version, // <- new attritbute }, ``` ``` pub trait ExportXcm { fn validate( network: NetworkId, channel: u32, universal_source: &mut Option<InteriorMultiLocation>, destination: &mut Option<InteriorMultiLocation>, message: &mut Option<Xcm<()>>, destination_xcm_version: Version, , // <- new attritbute ) -> SendResult<Self::Ticket>; ``` ## Future Directions This PR does not fix version discovery over bridge, further investigation will be conducted here: https://github.com/paritytech/polkadot-sdk/issues/2417. ## TODO - [x] `pallet_xcm` mock for tests uses hard-coded XCM version `2` - change to 3 or lastest? - [x] fix `pallet-xcm-bridge-hub-router` - [x] fix HaulBlobExporter with version determination [here](https://github.com/paritytech/polkadot-sdk/blob/2183669d/polkadot/xcm/xcm-builder/src/universal_exports.rs#L465) - [x] add unit-tests to the runtimes - [x] run benchmarks for `ExportMessage` - [x] extend local run scripts about `force_xcm_version(dest, version)` - [ ] when merged, prepare governance calls for Rococo/Westend - [ ] add PRDoc Part of: https://github.com/paritytech/parity-bridges-common/issues/2719 --------- Co-authored-by: command-bot <>

Using taplo, fixes all our broken and inconsistent toml formatting and adds CI to keep them tidy. If people want we can customise the format rules as described here https://taplo.tamasfe.dev/configuration/formatter-options.html @ggwpez , I suggest zepter is used only for checking features are propagated, and leave formatting for taplo to avoid duplicate work and conflicts. TODO - [x] Use `exclude = [...]` syntax in taplo file to ignore zombienet tests instead of deleting the dir --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: Bastian Köcher <[email protected]>

Right now governance could only control byte-fee component of Rococo <> Westend message fees (paid at Asset Hubs). This PR changes it a bit: 1) governance now allowed to control both fee components - byte fee and base fee; 2) base fee now includes cost of "default" delivery and confirmation transactions, in addition to `ExportMessage` instruction cost.

closes https://github.com/paritytech/polkadot-sdk/issues/1882 ## Breaking Changes This PR introduces a new item to `pallet_balances::Config`: ```diff trait Config { ++ type RuntimeFreezeReasons; } ``` This value is only used to check it against `type MaxFreeze`. A similar check has been added for `MaxHolds` against `RuntimeHoldReasons`, which is already given to `pallet_balances`. In all contexts, you should pass the real `RuntimeFreezeReasons` generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing `()` would also work, but it would imply that the runtime uses no freezes at all. --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: Oliver Tale-Yazdi <[email protected]>

The `xcm` crate was renamed to `staging-xcm` to be able to publish it to crates.io as someone as squatted `xcm`. The problem with this rename is that the `TypeInfo` includes the crate name which ultimately lands in the metadata. The metadata is consumed by downstream users like `polkadot-js` or people building on top of `polkadot-js`. These people are using the entire `path` to find the type in the type registry. Thus, their code would break as the type path would now be [`staging_xcm`, `VersionedXcm`] instead of [`xcm`, `VersionedXcm`]. This pull request fixes this by renaming the path segment `staging_xcm` to `xcm`. This requires: https://github.com/paritytech/scale-info/pull/197 --------- Co-authored-by: Francisco Aguirre <[email protected]>
