Functions

There are a lot of functions in the ERC721J.sol contract. 72 public functions, and a bunch of private functions too! I'll do my best to organize the public functions in an understandable order here.

Functions are separated into categories because there are so many. Every function that isn't from an interface is properly noted.

Categories

Metadata Functions

There are 4 read and 5 write functions related to metadata. Read more here.

Minting Functions

There are 10 write functions related to minting. Read more here.

Feature Functions

Promo System Functions

There are 4 read and 6 write functions related to the promo system. Read more here.

Other Functions

The unsorted misfit functions are below.

Write Functions

• setName - Lets the owner set the name for the contract.

• setSymbol - Lets the owner set the symbol for the contract.

• setVariables2 - Intended as the first function after initializing which sets the baseURI, contractURI and royaltyBPS all in one. Meant to be used once at the beginning as a way to initialize the collection with a profile. If you load into The Manager page right after minting a contract with The Contract Wizard, you will see a special button that is asking you to use this code.

• withdraw - Withdraws the ETH that was sent to the contract.
