I'm not anticipating there being any significant changes to the contract - operational things like precisely how redemptions are handled don't require changes to the contract.

MINING dividends would be paid daily as before regardless of where we relist (once the backlog had been cleared and any teething problems with relisting had been resolved).  i.e. I'd likely wait a day or two after relisting to make sure there were no problems with people having wrong number of shares or similar before paying outstanding dividends (though if we relist on the exchange currently planned then I could verify the list myself as I'd have access to a list similar to what I had on BTC-TC, so could check it myself).

Until/unless automated transfers could be implemented I'd likely impose some restrictions on trades of PURCHASE for MINING/SELLING (but anyone already holding PURCHASE would of course be allowed to swap) but everything else would be as before - though with redemption policy reflecting the reality that NAV/U is X BTC + Y CIPHERMINE.B1 until that changes.
