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:

In the move from the old `Currency` traits to the new `fungible/s` family of traits, we already had the `FungiblesAdapter` and `NonFungiblesAdapter` for multiple fungible and non fungible assets respectively. However, for handling only one fungible asset, we were missing a `FungibleAdapter`, and so used the old `CurrencyAdapter` instead. This PR aims to fill in that gap, and provide the new adapter for more updated examples. I marked the old `CurrencyAdapter` as deprecated as part of this PR, and I'll change it to the new `FungibleAdapter` in a following PR. The two stages are separated so as to not bloat this PR with some name fixes in tests. --------- Co-authored-by: command-bot <>

## 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 <>

This PR introduces a script and some templates to use the prdoc involved in a release and build: - the changelog - a simple draft of audience documentation Since the prdoc presence was enforced in the middle of the version 1.5.0, not all PRs did come with a `prdoc` file. This PR creates all the missing `prdoc` files with some minimum content allowing to properly generate the changelog. The generated content is **not** suitable for the audience documentation. The audience documentation will be possible with the next version, when all PR come with a proper `prdoc`. ## Assumptions - the prdoc files for release `vX.Y.Z` have been moved under `prdoc/X.Y.Z` - the changelog requires for now for the prdoc files to contain author + topic. Thos fields are optional. The build script can be called as: ``` VERSION=X.Y.Z ./scripts/release/build-changelogs.sh ``` Related: - #1408 --------- Co-authored-by:

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:

# 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 <>

## Overview This PR aligns the `spec_version` formatting to the [recent changes](https://github.com/polkadot-fellows/runtimes/pull/26/files#diff-efa4caeb17487ecb13d8f5eb7863c3241d84afa2e73fbf25909a2ca89df0f362R142 ) made for the Polkadot/Kusama runtimes. It also backports the latest version `v1.4.0` bumps as `1_004_000`. ## Details During the switch from `v0.9` to `v1.x`, the format of the `spec_version` was modified from: `(M)m_ppp` for a runtime considered on version `M.m.pp`. For instance `0.9.42` had a `spec_version` of `9420`. With the transition to `v1.x`, the format was changed to a bigger number (still `u32`) formatted as `MM_mm_ppp` where `1.2.3` would be stored as `01_02_003`. This PR aligns the format with that has been introduced in the fellowship repo: `MMM_mmm_ppp`. --------- Co-authored-by:

## 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).

We are introducing a new set of `XcmController` traits (final name yet to be determined). These traits are implemented by `pallet-xcm` and allows other pallets, such as `pallet_contracts`, to rely on these traits instead of tight coupling them to `pallet-xcm`. Using only the existing Xcm traits would mean duplicating the logic from `pallet-xcm` in these other pallets, which we aim to avoid. Our objective is to ensure that when these APIs are called from `pallet-contracts`, they produce the exact same outcomes as if called directly from `pallet-xcm`. The other benefits is that we can also expose return values to `pallet-contracts` instead of just calling `pallet-xcm` dispatchable and getting a `DispatchResult` back. See traits integration in this PR https://github.com/paritytech/polkadot-sdk/pull/1248 , where the traits are used as follow to define and implement `pallet-contracts` Config. ```rs // Contracts config: pub trait Config: frame_system::Config { // ... /// A type that exposes XCM APIs, allowing contracts to interact with other parachains, and /// execute XCM programs. type Xcm: xcm_executor::traits::Controller< OriginFor<Self>, <Self as frame_system::Config>::RuntimeCall, BlockNumberFor<Self>, >; } // implementation impl pallet_contracts::Config for Runtime { // ... type Xcm = pallet_xcm::Pallet<Self>; } ``` --------- Co-authored-by:

(imported from https://github.com/paritytech/cumulus/pull/2157) ## Changes This MR refactores the XCMP, Parachains System and DMP pallets to use the [MessageQueue](https://github.com/paritytech/substrate/pull/12485) for delayed execution of incoming messages. The DMP pallet is entirely replaced by the MQ and thereby removed. This allows for PoV-bounded execution and resolves a number of issues that stem from the current work-around. All System Parachains adopt this change. The most important changes are in `primitives/core/src/lib.rs`, `parachains/common/src/process_xcm_message.rs`, `pallets/parachain-system/src/lib.rs`, `pallets/xcmp-queue/src/lib.rs` and the runtime configs. ### DMP Queue Pallet The pallet got removed and its logic refactored into parachain-system. Overweight message management can be done directly through the MQ pallet. Final undeployment migrations are provided by `cumulus_pallet_dmp_queue::UndeployDmpQueue` and `DeleteDmpQueue` that can be configured with an aux config trait like: ```rust parameter_types! { pub const DmpQueuePalletName: &'static str = \"DmpQueue\" < CHANGE ME; pub const RelayOrigin: AggregateMessageOrigin = AggregateMessageOrigin::Parent; } impl cumulus_pallet_dmp_queue::MigrationConfig for Runtime { type PalletName = DmpQueuePalletName; type DmpHandler = frame_support::traits::EnqueueWithOrigin<MessageQueue, RelayOrigin>; type DbWeight = <Runtime as frame_system::Config>::DbWeight; } // And adding them to your Migrations tuple: pub type Migrations = ( ... cumulus_pallet_dmp_queue::UndeployDmpQueue<Runtime>, cumulus_pallet_dmp_queue::DeleteDmpQueue<Runtime>, ); ``` ### XCMP Queue pallet Removed all dispatch queue functionality. Incoming XCMP messages are now either: Immediately handled if they are Signals, enqueued into the MQ pallet otherwise. New config items for the XCMP queue pallet: ```rust /// The actual queue implementation that retains the messages for later processing. type XcmpQueue: EnqueueMessage<ParaId>; /// How a XCM over HRMP from a sibling parachain should be processed. type XcmpProcessor: ProcessMessage<Origin = ParaId>; /// The maximal number of suspended XCMP channels at the same time. #[pallet::constant] type MaxInboundSuspended: Get<u32>; ``` How to configure those: ```rust // Use the MessageQueue pallet to store messages for later processing. The `TransformOrigin` is needed since // the MQ pallet itself operators on `AggregateMessageOrigin` but we want to enqueue `ParaId`s. type XcmpQueue = TransformOrigin<MessageQueue, AggregateMessageOrigin, ParaId, ParaIdToSibling>; // Process XCMP messages from siblings. This is type-safe to only accept `ParaId`s. They will be dispatched // with origin `Junction::Sibling(…)`. type XcmpProcessor = ProcessFromSibling< ProcessXcmMessage< AggregateMessageOrigin, xcm_executor::XcmExecutor<xcm_config::XcmConfig>, RuntimeCall, >, >; // Not really important what to choose here. Just something larger than the maximal number of channels. type MaxInboundSuspended = sp_core::ConstU32<1_000>; ``` The `InboundXcmpStatus` storage item was replaced by `InboundXcmpSuspended` since it now only tracks inbound queue suspension and no message indices anymore. Now only sends the most recent channel `Signals`, as all prio ones are out-dated anyway. ### Parachain System pallet For `DMP` messages instead of forwarding them to the `DMP` pallet, it now pushes them to the configured `DmpQueue`. The message processing which was triggered in `set_validation_data` is now being done by the MQ pallet `on_initialize`. XCMP messages are still handed off to the `XcmpMessageHandler` (XCMP-Queue pallet) - no change here. New config items for the parachain system pallet: ```rust /// Queues inbound downward messages for delayed processing. /// /// Analogous to the `XcmpQueue` of the XCMP queue pallet. type DmpQueue: EnqueueMessage<AggregateMessageOrigin>; ``` How to configure: ```rust /// Use the MQ pallet to store DMP messages for delayed processing. type DmpQueue = MessageQueue; ``` ## Message Flow The flow of messages on the parachain side. Messages come in from the left via the `Validation Data` and finally end up at the `Xcm Executor` on the right. ![Untitled (1)](https://github.com/paritytech/cumulus/assets/10380170/6cf8b377-88c9-4aed-96df-baace266e04d) ## Further changes - Bumped the default suspension, drop and resume thresholds in `QueueConfigData::default()`. - `XcmpQueue::{suspend_xcm_execution, resume_xcm_execution}` errors when they would be a noop. - Properly validate the `QueueConfigData` before setting it. - Marked weight files as auto-generated so they wont auto-expand in the MR files view. - Move the `hypothetical` asserts to `frame_support` under the name `experimental_hypothetically` Questions: - [ ] What about the ugly `#[cfg(feature = \"runtime-benchmarks\")]` in the runtimes? Not sure how to best fix. Just having them like this makes tests fail that rely on the real message processor when the feature is enabled. - [ ] Need a good weight for `MessageQueueServiceWeight`. The scheduler already takes 80% so I put it to 10% but that is quite low. TODO: - [x] Remove c&p code after https://github.com/paritytech/polkadot/pull/6271 - [x] Use `HandleMessage` once it is public in Substrate - [x] fix `runtime-benchmarks` feature https://github.com/paritytech/polkadot/pull/6966 - [x] Benchmarks - [x] Tests - [ ] Migrate `InboundXcmpStatus` to `InboundXcmpSuspended` - [x] Possibly cleanup Migrations (DMP+XCMP) - [x] optional: create `TransformProcessMessageOrigin` in Substrate and replace `ProcessFromSibling` - [ ] Rerun weights on ref HW --------- Signed-off-by:

Closes https://github.com/paritytech/release-engineering/issues/6 Adds a new Github Workflow which on a new release being created, builds and attaches all runtimes managed in this repository in two flavours: - `dev-debug-build`: Built with the `try-runtime` feature and has logging enabled - `on-chain-release`: Built with the regular old `on-chain-release` feature The new Github Workflow could be extended in the future by the @paritytech/release-engineering team to fully automate the release process if they choose to, similar to how it is fully automated in the Fellowship repo (https://github.com/polkadot-fellows/runtimes/blob/main/.github/workflows/release.yml). The `on-chain-release` did not exist for parachains, so I added it. --- Tested on my fork: - https://github.com/liamaharon/polkadot-sdk/actions/runs/6663773523 - https://github.com/liamaharon/polkadot-sdk/releases/tag/test-6 --------- Co-authored-by:

# Description - What does this PR do? While working with `pallet_nfts` through `nonfungibles_v2` traits `Inspect, Mutate`, I found out that once you have set the collection attribute with `<Nfts as Mutate>::set_collection_attribute()`, it's not possible to read it with `<Nfts as Inspect>::collection_attribute()` since they use different `namespace` values. When setting the attribute, `AttributeNamespace::Pallet` is used, while `AttributeNamespace::CollectionOwner` is used when reading. more context: https://github.com/freeverseio/laos/issues/7#issuecomment-1766137370 This PR makes `item` an optional parameter in `Inspect::system_attribute()`, to be able to read collection attributes. - Why are these changes needed? To be able to read collection level attributes when reading attributes of the collection. It will be possible to read collection attributes by passing `None` for `item` - How were these changes implemented and what do they affect? `NftsApi` is also affected and `NftsApi::system_attribute()` now accepts optional `item` parameter. ## Breaking change Because of the change in the `NftsApi::system_attribute()` method's `item` param, parachains who integrated the `NftsApi` need to update their API code and frontend integrations accordingly. AssetHubs are unaffected since the NftsApi wasn't released on those parachains yet.

Adds a config file that allows to run `zepter` without any arguments in the workspace to address all issues. A secondary workflow for the CI is provided as `zepter run check`. Both the formatting and linting are now in one check for efficiancy. The latest version also detects some more things that `featalign` was already showing. Error message [in the CI](https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/3916205) now looks like this: ```pre ... crate 'test-parachains' (/Users/vados/Documents/work/polkadot-sdk/polkadot/parachain/test-parachains/Cargo.toml) feature 'std' must propagate to: parity-scale-codec Found 55 issues (run with --fix to fix). Error: Command 'lint propagate-feature' failed with exit code 1 Polkadot-SDK uses the Zepter CLI to detect abnormalities in the feature configuration. It looks like one more more checks failed; please check the console output. You can try to automatically address them by running `zepter`. Otherwise please ask directly in the Merge Request, GitHub Discussions or on Matrix Chat, thank you.

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:

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:

Combination of paritytech/polkadot#7005, its addon PR paritytech/polkadot#7585 and its companion paritytech/cumulus#2433. This PR introduces a new XcmFeesToAccount struct which implements the `FeeManager` trait, and assigns this struct as the `FeeManager` in the XCM config for all runtimes. The struct simply deposits all fees handled by the XCM executor to a specified account. In all runtimes, the specified account is configured as the treasury account. XCM __delivery__ fees are now being introduced (unless the root origin is sending a message to a system parachain on behalf of the originating chain). # Note for reviewers Most file changes are tests that had to be modified to account for the new fees. Main changes are in: - cumulus/pallets/xcmp-queue/src/lib.rs <- To make it track the delivery fees exponential factor - polkadot/xcm/xcm-builder/src/fee_handling.rs <- Added. Has the FeeManager implementation - All runtime xcm_config files <- To add the FeeManager to the XCM configuration # Important note After this change, instructions that create and send a new XCM (Query*, Report*, ExportMessage, InitiateReserveWithdraw, InitiateTeleport, DepositReserveAsset, TransferReserveAsset, LockAsset and RequestUnlock) will require the corresponding origin account in the origin register to pay for transport delivery fees, and the onward message will fail to be sent if the origin account does not have the required amount. This delivery fee is on top of what we already collect as tx fees in pallet-xcm and XCM BuyExecution fees! Wallet UIs that want to expose the new delivery fee can do so using the formula: ``` delivery_fee_factor * (base_fee + encoded_msg_len * per_byte_fee) ``` where the delivery fee factor can be obtained from the corresponding pallet based on which transport you are using (UMP, HRMP or bridges), the base fee is a constant, the encoded message length from the message itself and the per byte fee is the same as the configured per byte fee for txs (i.e. `TransactionByteFee`). --------- Co-authored-by:

## Summary This PR introduces several enhancements. The current implementation of `NetworkExportTable` lacks remote location filtering support beyond `NetworkId` lookup. To provide more control and granularity, it's essential to allow configuration for bridging to different consensus `NetworkId` while restricting access e.g. to particular remote parachains. Additionally, the `StartsWith` and `Equals` and `StartsWithExplicitGlobalConsensus` helper functions, which are in active use, are moved to the `xcm-builder` and `frame_support` modules for better code organization. Adds a new `LocationWithAssetFilters` filter to enable location-based and asset-related filtering. This filter is useful for configuring the `pallet_xcm` filter for [XcmTeleportFilter](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/pallet-xcm/src/lib.rs#L212) and [XcmReserveTransferFilter](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/pallet-xcm/src/lib.rs#L216 ) to restrict specific assets. Furthermore, the `BridgeMessage` fields are not accessible outside of `xcm-builder`, limiting the ability to create custom logic dependent on it. --------- Co-authored-by:

[xcm] Use `Weight::MAX` for `reserve_asset_deposited`, `receive_teleported_asset` benchmarks (#1726) # Description ## Summary Previously, the `pallet_xcm::do_reserve_transfer_assets` and `pallet_xcm::do_teleport_assets` functions relied on weight estimation for remote chain execution, which was based on guesswork derived from the local chain. This approach led to complications for runtimes that did not provide or support specific [XCM configurations](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76ef8fd2aabf9f07de0156941ce3ed44b0/polkadot/xcm/xcm-executor/src/config.rs#L43-L47) for `IsReserve` or `IsTeleporter`. Consequently, such runtimes had to resort to implementing hard-coded weights for XCM instructions like `reserve_asset_deposited` or `receive_teleported_asset` to support extrinsics such as `pallet_xcm::reserve_transfer_assets` and `pallet_xcm::teleport_assets`, which depended on remote weight estimation. The issue of remote weight estimation was addressed and resolved by [Pull Request #1645](https://github.com/paritytech/polkadot-sdk/pull/1645), which removed the need for remote weight estimation. ## Solution As a continuation of this improvement, the current PR proposes further cleanup by removing unnecessary hard-coded values and rectifying benchmark results with `Weight::MAX` that previously used `T::BlockWeights::get().max_block` as an override for unsupported XCM instructions like `ReserveAssetDeposited` and `ReceiveTeleportedAsset`. ## Questions - [x] Can we remove now also `Hardcoded till the XCM pallet is fixed` for `deposit_asset`? E.g. for AssetHubKusama [here](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76ef8fd2aabf9f07de0156941ce3ed44b0/cumulus/parachains/runtimes/assets/asset-hub-kusama/src/weights/xcm/mod.rs#L129-L134) - [x] Are comments like [this](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76ef8fd2aabf9f07de0156941ce3ed44b0/polkadot/runtime/kusama/src/weights/xcm/mod.rs#L94) `// Kusama doesn't support ReserveAssetDeposited, so this benchmark has a default weight` still relevant? Shouldnt be removed/changed? ## TODO - [x] `bench bot` regenerate xcm weights for all runtimes - [x] remove hard-coded stuff from system parachain weight files - [ ] when merged, open `polkadot-fellow/runtimes` PR ## References Fixes #1132 Closes #1132 Old polkadot repo [PR](https://github.com/paritytech/polkadot/pull/7546) --------- Co-authored-by: command-bot <>
