#260 Open and Accept HRMP channel between Amplitude and Statemine
Summary
This proposal from Pendulum aims to open an HRMP channel between Amplitude and Statemine and accept the request from Amplitude.
Details
As is usual for opening HRMP channels, the extrinsic consists of a batch of two calls:
A 11 KSM force transfer from Kusama treasury (F3opxRbN5ZbjJNU511Kj2TLuzFcDq9BGduA9TgiECafpg29) to Statemine (F7fq1jSNVTPfJmaHaXCMtatT1EZefCUsa7rRiQVNR5efcah) to pay for fees and for the deposit. Send XCM message to Statemine to execute a transaction with superuser (root) permission.

Overall 60 % of users are feeling neutral. There is uncertainty regarding whether a certain requirement is mandatory for the proposal update to be implemented. @paradox is asked for clarification on this matter. Those who voted against the proposal are encouraged to share their reasons for doing so.
Overall 40 % of users are feeling against it. The message about opening HRMP channels on OpenGov is incorrect. It is not necessary to use the new force_open_hrmp_channel method on the Relay Chain. The information provided is inaccurate and needs to be corrected.

Hello, please make sure to open this on OpenGov!
Is that mandatory and without that, will the proposal not be accepted update not be implemented?
To the nay voters: would be good to hear the reasoning for voting against 🙏
Just got word that this is not an accurate call. I'm working with Prayag to get things fixed.
@paradox , any further word on this?
Hey Bill,
Sorry to have missed this message. There's a new best practice for opening HRMP channels documented here.
Please ensure that you use the new force_open_hrmp_channel directly on the Relay Chain, rather than the old two-phase channel request/accept method.
I am in touch with Prayag from Amplitude as well as Joe to get the correct extrinsic crafted. This would also most likely require execution on the whitelist track and we'll also require a fellow to initiate a whitelist voter.
