Confirm that slow swap UMP is no longer needed #231

Closed clangenb closed 10 months ago

clangenb commented 10 months ago

I think I saw a PR merged into polkadot, which unlocks the parachain for the relay chain account that has reserved the para id, which means we no longer need to use XCM to perform the slot swap. This issue shall be the reminder that we have to confirm this.

I have found the corresponding RFC. It only only helps in a way that we no longer need to set up a second parachain, as it will only become locked after producing the first block:https://github.com/polkadot-fellows/RFCs/pull/14. Before that, we parachain manager account can request a slot swap on behalf of the parachain.

This means that the Integritee parachain does still need to send a UMP message to be able to request a slot swap.
