Event
Parameters
help
Event parameters list the data that an event contains.
| from |
address help
The type of this value is address, which means it stores an Ethereum address, such as a wallet address.
|
| to |
address help
The type of this value is address, which means it stores an Ethereum address, such as a wallet address.
|
| tokenId |
uint256 help
The type of this value is uint, which stands for unsigned integer. Integer means it's a whole number (such as 1, 12, 52) without fractions or decimals. Unsigned means it can't have a negative or positive sign, so it's always a positive number.

Properties
Visibility
help
Visibility determines if the function is visible to users and other contracts.
Only functions that are public can be used.
public
Mutability
help
Mutability tells you if a function can make changes on the blockchain.
View means the function can be called by anyone without
a wallet and without submitting a transaction.
transaction
Modifiers
help
Modifiers are additions to a function that typically make various checks before
the function is run.
onlyLexDAO
checks for the following:
Source Code
function mint(address to, string calldata _tokenURI) external onlyLexDAO {
_mint(to, _tokenURI);
}
mintBatch

Parameters

Function parameters list what input the function expects from the user. Each
parameter must be given a value.
| Name |
Type |
| to |
address[] help
The type of this value is address, which means it stores an Ethereum address, such as a wallet address. Because the type ends with '[]', that means it is an array. An array is just a list of values, rather than a single value.
|
| _tokenURI |
string[] help
The type of this value is string, which is basically just plain text. It's called a string because it is a 'string' of letters. Because the type ends with '[]', that means it is an array. An array is just a list of values, rather than a single value.

Requirements
help
Requirements are checks that the function makes when it runs, and give you
insight on what conditions are required for the function to succeed.

{
require(to.length == _tokenURI.length, "!to/tokenURI");
