Currently the xcm-executor returns an `Unimplemented` error if it receives any HRMP-related instruction. What I propose here, which is what we are currently doing in our forked executor at polimec, is to introduce a trait implemented by the executor which will handle those instructions. This way, if parachains want to keep the default behavior, they just use `()` and it will return unimplemented, but they can also implement their own logic to establish HRMP channels with other chains in an automated fashion, without requiring to go through governance. Our implementation is mentioned in the [polkadot HRMP docs](https://arc.net/l/quote/hduiivbu), and it was suggested to us to submit a PR to add these changes to polkadot-sdk. --------- Co-authored-by: Branislav Kontur <bkontur@gmail.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.
