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: Alexander Theißen <alex.theissen@me.com> Co-authored-by: command-bot <>
Rococo: v2.1
Rococo is a testnet runtime with no stability guarantees.
How to build rococo runtime
EpochDurationInBlocks parameter is configurable via ROCOCO_EPOCH_DURATION environment variable. To build wasm
runtime blob with customized epoch duration the following command shall be exectuted:
ROCOCO_EPOCH_DURATION=10 ./polkadot/scripts/build-only-wasm.sh rococo-runtime /path/to/output/directory/
How to run rococo-local
The Cumulus Tutorial details building, starting, and
testing rococo-local and parachains connecting to it.
How to register a parachain on the Rococo testnet
The parachain registration process on the public Rococo testnet is also outlined.
