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 <>
Substrate Cumulus Parachain Template
A new Cumulus-based Substrate node, ready for hacking ☁️..
This project is originally a fork of the Substrate Node Template modified to include dependencies required for registering this node as a parathread or parachain to a relay chain.
The stand-alone version of this template is hosted on the Substrate Devhub Parachain Template for each release of Polkadot. It is generated directly to the upstream Parachain Template in Cumulus at each release branch using the Substrate Template Generator.
👉 Learn more about parachains here, and parathreads here.
🧙 Learn about how to use this template and run your own parachain testnet for it in the Devhub Cumulus Tutorial.
