I have declared a function in my solidity code that is responsible for minting NFTs. However, Does anyone know how could I be able to mint a couple of NFTs in a single transaction with _safeMint() function inheriting from the ERC721?
Furthermore, If anyone makes me aware of the difference between _safeMint() and _mint(), I would appreciate it.
Here is my function and for loop;
In one transaction:
To mint one item, use _mint(...).
To mint up to 20 items, use _mint(...) in a for-loop.
To mint up to 500 items, use the "ghost minting" technique. Please see the Area NFT contract for an open source example of that. Note this is an advanced technique that will surely require customization based on your application.
To mint enough tokens to track ownership of nanobots a few micron in size and in aggregate totaling half the size of Earth, use the "lazy array" technique. Please see the Su Squares contract for an open source example of that. This is only possible at the time of contract deployment.
The _safeMint(...) function makes the recipient of a token, if it's a contract, get a onERC721Received(...) call. This functionality is not required by the standard and you may have some specific reason you want to use that.
I did test with 10000 tokens in the loop. It works fine but the transaction is going to be heavy and took almost 50 seconds in my local private network.
