Bytes[] memory conversion to bytes[] calldata

@spalladino Thanks for the answer. Here are two other posts that can show where I came from.

ERC20 batchTransfer functionality

I like this abstraction, however, would there be an example walking us through a use case? function multicall(bytes[] calldata data) external returns (bytes[] memory results) { results = new bytes[](data.length); for (uint i = 0; i < data.length; i++) { results[i] = Address.functionDelegateCall(address(this), data[i]); } return results; } Like how someone can pass input parameters and what will be returned? No example can be better than a batchTransfer of ERC20 tokens. …

Best/standard approach for minting 10000 NFTs

Hi there, wondering what the best approach of mining 10000 or more NFTs is? I’ve come up a few approaches listed below: 1). A single function mint() with no for loop inside with which only 1 NFT can be minted each time the function is called. The function will be called 10000 times; 2). A single function batchMint() with a for loop inside with which up to 100 NFTs can be minted each time. The function will be called 100 times; 3). A single function batchMint() with a for loop inside with whic…

Basically, what we would like to achieve is an automatic batch minting mechanism that is invoked not by the contract or project owner but by any contract calller, i.e., anyone could call a function in a smart contract and invoke a batch minting of ERC721 tokens.

We are currently using a for loop, which is linear and sequential in a single transaction. The name multicall gives me a sense that it has a parallel mechanism built in, sort of like multi-processing in Python. It looks like it is not. multicall is also sending calling messages in a linear fashion, correct? I would also assume it takes similar amount of gas to a function with a for loop and high-level calls, for a task like making a transfer, correct?

Now, coming back to the way of using multicall, is it possible to create an array of calldata and get it passed to this function in Solidity, as described in the original question?

Thanks.
