Next peerdas devnet will be peerdas-devnet-7, launching after Pectra once sync issues are fixed.

Sunnyside Labs is running an instance of peerdas-devnet-6 in the mean time.


Ideally we also include validator custody in peerdas-devnet-7 along with other bug fixes, although we likely need more progress with implementation here before including in peerdas-devnet-7.
We discussed the exact specs for peerdas-devnet-7 which are forthcoming.
Had a call out to review the BPO infra for upcoming peerdas devnets
