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 <>
Parachains
This directory is the home of Parity-developed parachain runtimes. This directory is runtime focused, and does not include builds of parachain nodes.
The general internal structure is:
chain-specs: Chain specs for the runtimes contained in its sibling dirruntimes.common: Common configurations,impls, etc. used by several parachain runtimes.integration-tests: Integration tests to test parachain interactions via XCM.pallets: FRAME pallets that are specific to parachains.runtimes: The entry point for parachain runtimes.
System Parachains
The runtimes directory includes many, but is not limited to,
system parachains. Likewise, not all
system parachains are in this repo.
Releases
The project maintainers generally try to release a set of parachain runtimes for each Polkadot Relay Chain runtime release.
