It makes sense to deprecate the Altair chain for the reasons shared. I’ll personally be surprised if anyone / any party wants to take over managing it.
However, I have deep concerns about what becomes of the AIR token. There are many people / groups who have invested into the token for a variety of reasons.
What do you foresee becoming of the AIR token @jeroen?
I’ll share this RFC which I posted months ago about the topic.
If the Altair chain is set to be deprecated, it is only fair we come up with a reasonable plan for AIR token holders to migrate their tokens to EVM as CFG with a respectable exchange rate.
