How do I set the price automatically?

Question

I have a question related to billing for NFT, is it possible to prescribe in the smart contract function to set the price ? The problem is that after posting the nft you need to press Salle, set the price, I would like to automate this

Answer 1

It depends on when you want to set the price. You can use msg.value to make sure they send you ETH (or whatever your native smart contract token is)

1. On mint: You just add a require statement under your minting function. ie:

function mint() public {
  require(msg.value > [SOME_PRICE_IN_WEI]);
.
.
.

2. On "resell" You could also force the transfer and transferFrom functions to have this same require statement.

3. On a UI like Opensea Most UIs like Opensea have the functionality to set a price of an NFT.

Hope it helps.
