This proposal is proposed by Acala Foundation to increase HRMP open request time-to-live from 2 sessions to 72 sessions (3 days).

We are also requesting technical committee to fast track this so it can be applied before 9th September in order for parachain teams to continue implementing cross chain interaction on Kusama.

Context:

In order to parachain to send XCM to other parachain, a HRMP channel must be established first. One parachain must send a HRMP channel open request, and the other parachain needs to accept the request before it expires. The current expiration time is 2 sessions, which is 2 hours.

Parachain sovereign origin is required send / accept a HRMP channel open request. Parachain sovereign origin have a lot of permissions including control all the reserved transferred KSM in the parachain and therefore a root call on parachain is required perform such request. On most parachain, a democracy referendum is required to make a root call and as it requires token holders to vote. This usually takes multiple days. While fast track may be possible, it is still not feasible to require parachains to only have 2 hours time window to vote on a HRMP channel open request.

This proposal request increase the HRMP open request time-to-live from 2 hours to 3 days so it is possible for parachains to vote on open requests and decide to accept or reject it.
