PNK minting and 2nd token sale - rights issue - preferential treatment for current holders

[marsrobertson]

@martijn

Is it hard (from a technical standpoint) to whitelist current PNK holders and let them buy first for a certain period?

No, not really. I’ll show you how…

Also from the sister thread:

@0xferit

Instead of this, I think we can whitelist holders and disable buying in first day except for whitelisted accounts.

@clesaege

That can be done too, but that’s extra dev work, extra complexity and we’ll lose some buyers which will shows up the first day but don’t have PNK.

I was away from keyboard for the weekend and I thought about opening the sale to existing holders for 24 hours before the thing.

It’s relatively simple. Here is some PSEUDOCODE:

// or move month to the future to allow more time for marketing efforts
timestamp DateStart = 11th of January 2020 16:00 UTC 
timestamp CurrentHoldersOpenWindow  = 1 day

uint PNKSnapshotAmount = PNK.getBalaceOfAtBlock(someblock, msg.sender)

// ...in the buy() function...

if (PNKPurchasedNow <= PNKSnapshotAmount) { // bying within our limit
  require(time.now > DateStart)
} else { //  more PNK than the amount allowe
  require(time.now > DateStart + CurrentHoldersOpenWindow)
}

The buyer will have to calculate themselves on the on the front-end how much PNK they are allowed to buy in the initial opening period.

If they have 100k PNK but send ETH to but 110k PNK rather than calculating refunds on the smart contract, we are simply reverting.
