Introduce types to define 1:1 balance conversion for different relative asset ids/locations of native asset. Examples: native asset on Asset Hub presented as `VersionedLocatableAsset` type in the context of Relay Chain is ``` { `location`: (0, Parachain(1000)), `asset_id`: (1, Here), } ``` and it's balance should be converted 1:1 by implementations of `ConversionToAssetBalance` trait. --------- Co-authored-by: Branislav Kontur <[email protected]>

This PR mainly removes `xcm::v3` stuff from `assets-common` to make it more generic and facilitate the transition to newer XCM versions. Some of the implementations here used hard-coded `xcm::v3::Location`, but now it's up to the runtime to configure according to its needs. Additional/consequent changes: - `penpal` runtime uses now `xcm::latest::Location` for `pallet_assets` as `AssetId`, because we don't care about migrations here - it pretty much simplify xcm-emulator integration tests, where we don't need now a lots of boilerplate conversions: ``` v3::Location::try_from(...).expect("conversion works")` ``` - xcm-emulator tests - split macro `impl_assets_helpers_for_parachain` to the `impl_assets_helpers_for_parachain` and `impl_foreign_assets_helpers_for_parachain` (avoids using hard-coded `xcm::v3::Location`)

# Description Add `transfer_assets_using()` for transferring assets from local chain to destination chain using explicit XCM transfer types such as: - `TransferType::LocalReserve`: transfer assets to sovereign account of destination chain and forward a notification XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - `TransferType::DestinationReserve`: burn local assets and forward a notification to `dest` chain to withdraw the reserve assets from this chain's sovereign account and deposit them to `beneficiary`. - `TransferType::RemoteReserve(reserve)`: burn local assets, forward XCM to `reserve` chain to move reserves from this chain's SA to `dest` chain's SA, and forward another XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. Typically the remote `reserve` is Asset Hub. - `TransferType::Teleport`: burn local assets and forward XCM to `dest` chain to mint/teleport assets and deposit them to `beneficiary`. By default, an asset's reserve is its origin chain. But sometimes we may want to explicitly use another chain as reserve (as long as allowed by runtime `IsReserve` filter). This is very helpful for transferring assets with multiple configured reserves (such as Asset Hub ForeignAssets), when the transfer strictly depends on the used reserve. E.g. For transferring Foreign Assets over a bridge, Asset Hub must be used as the reserve location. # Example usage scenarios ## Transfer bridged ethereum ERC20-tokenX between ecosystem parachains. ERC20-tokenX is registered on AssetHub as a ForeignAsset by the Polkadot<>Ethereum bridge (Snowbridge). Its asset_id is something like `(parents:2, (GlobalConsensus(Ethereum), Address(tokenX_contract)))`. Its _original_ reserve is Ethereum (only we can't use Ethereum as a reserve in local transfers); but, since tokenX is also registered on AssetHub as a ForeignAsset, we can use AssetHub as a reserve. With this PR we can transfer tokenX from ParaA to ParaB while using AssetHub as a reserve. ## Transfer AssetHub ForeignAssets between parachains AssetA created on ParaA but also registered as foreign asset on Asset Hub. Can use AssetHub as a reserve. And all of the above can be done while still controlling transfer type for `fees` so mixing assets in same transfer is supported. # Tests Added integration tests for showcasing: - transferring local (not bridged) assets from parachain over bridge using local Asset Hub reserve, - transferring foreign assets from parachain to Asset Hub, - transferring foreign assets from Asset Hub to parachain, - transferring foreign assets from parachain to parachain using local Asset Hub reserve. --------- Co-authored-by: Branislav Kontur <[email protected]> Co-authored-by: command-bot <>

This PR includes the following 2 improvements: ## Ethereum Client Author: @yrong ### Original Upstream PRs - https://github.com/Snowfork/polkadot-sdk/pull/123 - https://github.com/Snowfork/polkadot-sdk/pull/125 ### Description The Ethereum client syncs beacon headers as they are finalized, and imports every execution header. When a message is received, it is verified against the import execution header. This is unnecessary, since the execution header can be sent with the message as proof. The recent Deneb Ethereum upgrade made it easier to locate the relevant beacon header from an execution header, and so this improvement was made possible. This resolves a concern @svyatonik had in our initial Rococo PR: https://github.com/paritytech/polkadot-sdk/pull/2522#discussion_r1431270691 ## Inbound Queue Author: @yrong ### Original Upstream PR - https://github.com/Snowfork/polkadot-sdk/pull/118 ### Description When the AH sovereign account (who pays relayer rewards) is depleted, the inbound message will not fail. The relayer just will not receive rewards. Both these changes were done by @yrong, many thanks.

Currently `transfer_assets` from pallet-xcm covers 4 main different transfer types: - `localReserve` - `DestinationReserve` - `Teleport` - `RemoteReserve` For the first three, the local execution and the remote message sending are separated, and fees are deducted in pallet-xcm itself: https://github.com/paritytech/polkadot-sdk/blob/3410dfb3929462da88be2da813f121d8b1cf46b3/polkadot/xcm/pallet-xcm/src/lib.rs#L1758 . For the 4th case `RemoteReserve`, pallet-xcm is still relying on the xcm-executor itself to send the message (through the `initiateReserveWithdraw` instruction). In this case, if delivery fees need to be charged, it is not possible to do so because the `jit_withdraw` mode has not being set. This PR proposes to still use the `initiateReserveWithdraw` but prepending a `setFeesMode { jit_withdraw: true }` to make sure delivery fees can be paid. A test-case is also added to present the aforementioned case --------- Co-authored-by: Adrian Catangiu <[email protected]>

Issues addressed in this PR: - Improve *Penpal* runtime: - Properly handled received assets. Previously, it treated `(1, Here)` as the local native currency, whereas it should be treated as a `ForeignAsset`. This wasn't a great example of standard Parachain behaviour, as no Parachain treats the system asset as the local currency. - Remove `AllowExplicitUnpaidExecutionFrom` the system. Again, this wasn't a great example of standard Parachain behaviour. - Move duplicated `ForeignAssetFeeAsExistentialDepositMultiplierFeeCharger` to `assets_common` crate. - Improve emulated tests: - Update *Penpal* tests to new runtime. - To simplify tests, register the reserve transferred, teleported, and system assets in *Penpal* and *AssetHub* genesis. This saves us from having to create the assets repeatedly for each test - Add missing test case: `reserve_transfer_assets_from_para_to_system_para`. - Cleanup. - Prevent integration tests crates imports from being re-exported, as they were polluting the `polkadot-sdk` docs. There is still a test case missing for reserve transfers: - Reserve transfer of system asset from *Parachain* to *Parachain* trough *AssetHub*. - This is not yet possible with `pallet-xcm` due to the reasons explained in https://github.com/paritytech/polkadot-sdk/pull/3339 --------- Co-authored-by: command-bot <>

The current `penpal` runtime utilizes the `EthereumLocation` parameter, which is employed for XCM emulated integration tests concerning the Rococo <> ETH bridge. It includes a hard-coded chainId for the Ethereum testnet utilized in Rococo. The `EthereumLocation` serves the purpose of aligning with the `TrustedReserves`. However, due to this hard-coded configuration, reusing `penpal` for testing various environments such as Kusama/Polkadot versus Ethereum bridge becomes unfeasible. This PR introduces the capability to easily customize the asset location for `TrustedReserves` without needing to know anything about Ethereum. ## TODO - [x] fix integration tests with `System::set_storage(CustomizableAssetFromSystemAssetHub::key(), <whatever-location-is-needed>)` @claravanstaden - [ ] ~~maybe add some helper function/macro to support `set_storage` for other runtimes (that we could reuse)~~ - [ ] Release patch for: `penpal-runtime` + emulated crate with `set_storage` support (if needed) - [ ] backport to 1.7.0 - [ ] backport to 1.8.0 --------- Co-authored-by: Clara van Staden <[email protected]>

This fix aims to solve an issue in Kusama that resulted in failed reserve asset transfers. During multi-hop XCMs, like reserve asset transfers where the reserve is not the sender nor the destination, but a third remote chain, the origin is not available to pay for delivery fees out of their account directly, so delivery fees should be paid out of transferred assets. This commit also adds an xcm-emulator regression test that validates this scenario is now working.

# 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.

Implements an XCM executor `WeightTrader`, facilitating fee payments in any asset that can be exchanged for a native asset. A few constraints need to be observed: - `buy_weight` and `refund` operations must be atomic, as another weight trader implementation might be attempted in case of failure. - swap credit must be utilized since there isn’t an account to which an asset of some class can be deposited with a guarantee to meet the existential deposit requirement.

closes https://github.com/paritytech/polkadot-sdk/issues/1842 Decoupling Pallet from the Concept of Native Currency Currently, the pallet is intrinsically linked with the concept of native currency, requiring users to provide implementations of the `fungible::*` and `fungibles::*` traits to interact with native and non native assets. This incapsulates some non-related to the pallet complexity and makes it less adaptable in contexts where the native currency concept is absent. With this PR, the dependence on `fungible::*` for liquidity-supplying assets has been removed. Instead, the native and non-native currencies' handling is now overseen by a single type that implements the `fungibles::*` traits. To simplify this integration, types have been introduced to facilitate the creation of a union between `fungible::*` and `fungibles::*` implementations, producing a unified `fungibles::*` type. One of the reasons driving these changes is the ambition to create a more user-friendly API for the `SwapCredit` implementation. Given that it interacts with two distinct credit types from `fungible` and `fungibles`, a unified type was introduced. Clients now manage potential conversion failures for those credit types. In certain contexts, it's vital to guarantee that operations are fail-safe, like in this impl - [PR](https://github.com/paritytech/polkadot-sdk/pull/1845), place in [code](https://github.com/paritytech/polkadot-sdk/blob/20b85a5fada8f55c98ba831964f5866ffeadf4da/cumulus/primitives/utility/src/lib.rs#L429). Additional Updates: - abstracted the pool ID and its account derivation logic via trait bounds, along with common implementation offerings; - removed `inc_providers` on a pool creation for the pool account; - benchmarks: -- swap complexity is N, not const; -- removed `From<u128> + Into<u128>` bound from `T::Balance`; -- removed swap/liquidity/.. amount constants, resolve them dynamically based on pallet configuration; -- migrated to v2 API; - `OnUnbalanced` handler for the pool creation fee, replacing direct transfers to a specified account ID; - renamed `MultiAssetId` to `AssetKind` aligning with naming across frame crates; related PRs: - (depends) https://github.com/paritytech/polkadot-sdk/pull/1677 - (caused) https://github.com/paritytech/polkadot-sdk/pull/2033 - (caused) https://github.com/paritytech/polkadot-sdk/pull/1876 --------- Co-authored-by: joe petrowski <[email protected]> Co-authored-by: Liam Aharon <[email protected]>

Introduces a swap implementation that allows the exchange of a credit (aka Negative Imbalance) of one asset for a credit of another asset. This is particularly useful when a credit swap is required but may not have sufficient value to meet the ED constraint, hence cannot be deposited to temp account before. An example use case is when XCM fees are paid using an asset held in the XCM executor registry and has to be swapped for native currency. Additional Updates: - encapsulates the existing `Swap` trait impl within a transactional context, since partial storage mutation is possible when an error occurs; - supplied `Currency` and `Assets` impls must be implemented over the same `Balance` type, the `AssetBalance` generic type is dropped. This helps to avoid numerous type conversion and overflow cases. If those types are different it should be handled outside of the pallet; - `Box` asset kind on a pallet level, unbox on a runtime level - here [why](https://substrate.stackexchange.com/questions/10039/boxed-argument-of-a-dispatchable/10103#10103); - `path` uses `Vec` now, instead of `BoundedVec` since it is never used in PoV; - removes the `Transfer` event due to it's redundancy with the events emitted by `fungible/s` implementations; - modifies the `SwapExecuted` event type; related issue: - https://github.com/paritytech/polkadot-sdk/issues/105 related PRs: - (required for) https://github.com/paritytech/polkadot-sdk/pull/1845 - (caused) https://github.com/paritytech/polkadot-sdk/pull/1717 // DONE make the pallet work only with `fungibles` trait and make it free from the concept of a `native` asset - https://github.com/paritytech/polkadot-sdk/issues/1842 --------- Co-authored-by: joe petrowski <[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.

## 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/63ac2471aa0210f0ac9903bdd7d8f9351f9a635f/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/2183669d05f9b510f979a0cc3c7847707bacba2e/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 <>

Treasury Pallet Instance for the Fellowship in Westend Collectives. In this update, we present a Treasury Pallet Instance that is under the control of the Fellowship body, with oversight from the Root and Treasurer origins. Here's how it is governed: - the Root origin have the authority to reject or approve spend proposals, with no amount limit for approvals. - the Treasurer origin have the authority to reject or approve spend proposals, with approval limits of up to 10,000,000 DOT. - Voice of all Fellows ranked at 3 or above can reject or approve spend proposals, with a maximum approval limit of 10,000 DOT. - Voice of Fellows ranked at 4 or above can also reject or approve spend proposals, with a maximum approval limit of 10,000,000 DOT. Additionally, we introduce the Asset Rate Pallet Instance to establish conversion rates from asset A to B. This is used to determine if a proposed spend amount involving a non-native asset is permissible by the commanding origin. The rates can be set up by the Root, Treasurer origins, or Voice of all Fellows. --------- Co-authored-by: joe petrowski <[email protected]> Co-authored-by: joepetrowski <[email protected]>

# Motivation (+testing) ### Enable easy `ForeignAssets` transfers using `pallet-xcm` We had just previously added capabilities to teleport fees during reserve-based transfers, but what about reserve-transferring fees when needing to teleport some non-fee asset? This PR aligns everything under either explicit reserve-transfer, explicit teleport, or this new flexible `transfer_assets()` which can mix and match as needed with fewer artificial constraints imposed to the user. This will enable, for example, a (non-system) parachain to teleport their `ForeignAssets` assets to AssetHub while using DOT to pay fees. (the assets are teleported - as foreign assets should from their owner chain - while DOT used for fees can only be reserve-based transferred between said parachain and AssetHub). Added `xcm-emulator` tests for this scenario ^. # Description Reverts `(limited_)reserve_transfer_assets` to only allow reserve-based transfers for all `assets` including fees. Similarly `(limited_)teleport_assets` only allows teleports for all `assets` including fees. For complex combinations of asset transfers where assets and fees may have different reserves or different reserve/teleport trust configurations, users can use the newly added `transfer_assets()` extrinsic which is more flexible in allowing more complex scenarios. `assets` (excluding `fees`) must have same reserve location or otherwise be teleportable to `dest`. No limitations imposed on `fees`. - for local reserve: transfer assets to sovereign account of destination chain and forward a notification XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for destination reserve: burn local assets and forward a notification to `dest` chain to withdraw the reserve assets from this chain's sovereign account and deposit them to `beneficiary`. - for remote reserve: burn local assets, forward XCM to reserve chain to move reserves from this chain's SA to `dest` chain's SA, and forward another XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for teleports: burn local assets and forward XCM to `dest` chain to mint/teleport assets and deposit them to `beneficiary`. ## Review notes Only around 500 lines are prod code (see `pallet_xcm/src/lib.rs`), the rest of the PR is new tests and improving existing tests. --------- 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.

## Motivation `pallet-xcm` is the main user-facing interface for XCM functionality, including assets manipulation functions like `teleportAssets()` and `reserve_transfer_assets()` calls. While `teleportAsset()` works both ways, `reserve_transfer_assets()` works only for sending reserve-based assets to a remote destination and beneficiary when the reserve is the _local chain_. ## Solution This PR enhances `pallet_xcm::(limited_)reserve_withdraw_assets` to support transfers when reserves are other chains. This will allow complete, **bi-directional** reserve-based asset transfers user stories using `pallet-xcm`. Enables following scenarios: - transferring assets with local reserve (was previously supported iff asset used as fee also had local reserve - now it works in all cases), - transferring assets with reserve on destination, - transferring assets with reserve on remote/third-party chain (iff assets and fees have same remote reserve), - transferring assets with reserve different than the reserve of the asset to be used as fees - meaning can be used to transfer random asset with local/dest reserve while using DOT for fees on all involved chains, even if DOT local/dest reserve doesn't match asset reserve, - transferring assets with any type of local/dest reserve while using fees which can be teleported between involved chains. All of the above is done by pallet inner logic without the user having to specify which scenario/reserves/teleports/etc. The correct scenario and corresponding XCM programs are identified, and respectively, built automatically based on runtime configuration of trusted teleporters and trusted reserves. #### Current limitations: - while `fees` and "non-fee" `assets` CAN have different reserves (or fees CAN be teleported), the remaining "non-fee" `assets` CANNOT, among themselves, have different reserve locations (this is also implicitly enforced by `MAX_ASSETS_FOR_TRANSFER=2`, but this can be safely increased in the future). - `fees` and "non-fee" `assets` CANNOT have **different remote** reserves (this could also be supported in the future, but adds even more complexity while possibly not being worth it - we'll see what the future holds).
