Do we need to have two different mintPrice?

[lawweiliang]

Presale nft price should be lower than publicSale nft price? Right?

Business logic

• Presale - if you get in, you get discounted price
• PublicSale - Market Price, usually higher than the presale price

Benefits

• Good for marketing (people will keep on retweet to get into the preSale list)

Problem with this implementation

• Refund is getting more complex because it need to keep track of two different price.

Any clue on this?

Hey,

So for a lot of projects having mint list sale and public sale at the same price makes sense. But it's up to each team to decide this. A different approach needs to be taken if the price differs. One solution is to store the mint price for each tokenId.

For CryptoFighters we do have two price ranges because v1 holders get a discounted rate on the upgrade. The example contract has more on it. I will try upload the new CF example soon. We'll probably remove it from this repo and just link to it as an example.

Here we refund holders at different prices: https://github.com/exo-digital-labs/ERC721R/blob/main/contracts/cryptofighters/CryptoFightersV2.sol#L117
