• why price? do you want to settle the stripe payment via oracle? would be perfect but harder than what was asked for today
• also you may need an accepted currency to settle

we also had these thoughts for the general macro view:

@2075 We didn't plan to use price in any way at the moment. Just store it for future. But we may also skip it for now.
Apart from that, if everything looks good @FiberMan starts to work on the implementation.

Should we use gamedao-protocol or zero-network repo to create this pallet in?

[2075]

it belongs to gamedao, so should be there imho, let's ship it

[2075]

any update here? @FiberMan

btw we can also use uniques pallet if we decide to.
