This should remove nearly all usage of `sp-std` except: - bridge and bridge-hubs - a few of frames re-export `sp-std`, keep them for now - there is a usage of `sp_std::Writer`, I don't have an idea how to move it Please review proc-macro carefully. I'm not sure I'm doing it the right way. Note: need `/bot fmt` --------- Co-authored-by:

Closes: https://github.com/paritytech/polkadot-sdk/issues/4298 This PR also merges `xcm-fee-payment-runtime-api` module to the `xcm-runtime-api`. ## TODO - [x] rename `convert` to `convert_location` and add new one `convert_account` (opposite direction) - [x] add to the all testnet runtimes - [x] check polkadot-js if supports that automatically or if needs to be added manually https://github.com/polkadot-js/api/pull/5917 - [ ] backport/patch for fellows and release (asap) ## Open questions - [x] should we merge `xcm-runtime-api` and `xcm-fee-payment-runtime-api` to the one module `xcm-runtime-api` ? ## Usage Input: - `location: VersionedLocation` Output: - account_id bytes  --------- Co-authored-by:

Follow-up to the new `XcmDryRunApi` runtime API introduced in https://github.com/paritytech/polkadot-sdk/pull/3872. Taking an extrinsic means the frontend has to sign first to dry-run and once again to submit. This is bad UX which is solved by taking an `origin` and a `call`. This also has the benefit of being able to dry-run as any account, since it needs no signature. This is a breaking change since I changed `dry_run_extrinsic` to `dry_run_call`, however, this API is still only on testnets. The crates are bumped accordingly. As a part of this PR, I changed the name of the API from `XcmDryRunApi` to just `DryRunApi`, since it can be used for general dry-running :) Step towards https://github.com/paritytech/polkadot-sdk/issues/690. Example of calling the API with PAPI, not the best code, just testing :) ```ts // We just build a call, the arguments make it look very big though. const call = localApi.tx.XcmPallet.transfer_assets({ dest: XcmVersionedLocation.V4({ parents: 0, interior: XcmV4Junctions.X1(XcmV4Junction.Parachain(1000)) }), beneficiary: XcmVersionedLocation.V4({ parents: 0, interior: XcmV4Junctions.X1(XcmV4Junction.AccountId32({ network: undefined, id: Binary.fromBytes(encodeAccount(account.address)) })) }), weight_limit: XcmV3WeightLimit.Unlimited(), assets: XcmVersionedAssets.V4([{ id: { parents: 0, interior: XcmV4Junctions.Here() }, fun: XcmV3MultiassetFungibility.Fungible(1_000_000_000_000n) } ]), fee_asset_item: 0, }); // We call the API passing in a signed origin const result = await localApi.apis.XcmDryRunApi.dry_run_call( WestendRuntimeOriginCaller.system(DispatchRawOrigin.Signed(account.address)), call.decodedCall ); if (result.success && result.value.execution_result.success) { // We find the forwarded XCM we want. The first one going to AssetHub in this case. const xcmsToAssetHub = result.value.forwarded_xcms.find(([location, _]) => ( location.type === "V4" && location.value.parents === 0 && location.value.interior.type === "X1" && location.value.interior.value.type === "Parachain" && location.value.interior.value.value === 1000 ))!; // We can even find the delivery fees for that forwarded XCM. const deliveryFeesQuery = await localApi.apis.XcmPaymentApi.query_delivery_fees(xcmsToAssetHub[0], xcmsToAssetHub[1][0]); if (deliveryFeesQuery.success) { const amount = deliveryFeesQuery.value.type === "V4" && deliveryFeesQuery.value.value[0].fun.type === "Fungible" && deliveryFeesQuery.value.value[0].fun.value.valueOf() || 0n; // We store them in state somewhere. setDeliveryFees(formatAmount(BigInt(amount))); } } ``` --------- Co-authored-by:

# Context Estimating fees for XCM execution and sending has been an area with bad UX. The addition of the [XcmPaymentApi](https://github.com/paritytech/polkadot-sdk/pull/3607) exposed the necessary components to be able to estimate XCM fees correctly, however, that was not the full story. The `XcmPaymentApi` works for estimating fees only if you know the specific XCM you want to execute or send. This is necessary but most UIs want to estimate the fees for extrinsics, they don't necessarily know the XCM program that's executed by them. # Main addition A new runtime API is introduced, the `XcmDryRunApi`, that given an extrinsic, or an XCM program, returns its effects: - Execution result - Local XCM (in the case of an extrinsic) - Forwarded XCMs - List of events This API can be used on its own for dry-running purposes, for double-checking or testing, but it mainly shines when used in conjunction with the `XcmPaymentApi`. UIs can use these two APIs to estimate transfers. # How it works New tests are added to exemplify how to incorporate both APIs. There's a mock test just to make sure everything works under `xcm-fee-payment-runtime-api`. There's a real-world test using Westend and AssetHubWestend under `cumulus/parachains/integration-tests/emulated/tests/assets/asset-hub-westend/src/tests/xcm_fee_estimation.rs`. Added both a test for a simple teleport between chains and a reserve transfer asset between two parachains going through a reserve. The steps to follow: - Use `XcmDryRunApi::dry_run_extrinsic` to get local XCM program and forwarded messages - For each forwarded message - Use `XcmPaymentApi::query_delivery_fee` LOCALLY to get the delivery fees - Use `XcmPaymentApi::query_xcm_weight` ON THE DESTINATION to get the remote execution weight - (optional) Use `XcmPaymentApi::query_acceptable_payment_assets` ON THE DESTINATION to know on which assets the execution fees can be paid - Use `XcmPaymentApi::query_weight_to_asset_fee` ON THE DESTINATION to convert weight to the actual remote execution fees - Use `XcmDryRunApi::dry_run_xcm` ON THE DESTINATION to know if a new message will be forwarded, if so, continue # Dear reviewer The changes in this PR are grouped as follows, and in order of importance: - Addition of new runtime API - Definition, mock and simple tests: polkadot/xcm/xcm-fee-payment-runtime-api/* - Implemented on Westend, Asset Hub Westend and Penpal, will implement on every runtime in a following PR - Addition of a new config item to the XCM executor for recording xcms about to be executed - Definition: polkadot/xcm/xcm-executor/* - Implementation: polkadot/xcm/pallet-xcm/* - had to update all runtime xcm_config.rs files with `type XcmRecorder = XcmPallet;` - Addition of a new trait for inspecting the messages in queues - Definition: polkadot/xcm/xcm-builder/src/routing.rs - Implemented it on all routers: - ChildParachainRouter: polkadot/runtime/common/src/xcm_sender.rs - ParentAsUmp: cumulus/primitives/utility/src/lib.rs (piggybacked on implementation in cumulus/pallets/parachain-system/src/lib.rs) - XcmpQueue: cumulus/pallets/xcmp-queue/src/lib.rs - Bridge: bridges/modules/xcm-bridge-hub-router/src/lib.rs - More complicated and useful tests: - cumulus/parachains/integration-tests/emulated/tests/assets/asset-hub-westend/src/tests/xcm_fee_estimation.rs ## Next steps With this PR, Westend, AssetHubWestend, Rococo and AssetHubRococo have the new API. UIs can test on these runtimes to create better experiences around cross-chain operations. Next: - Add XcmDryRunApi to all system parachains - Integrate xcm fee estimation in all emulated tests - Get this on the fellowship runtimes --------- Co-authored-by:
