A JavaScript question, how do I get the nftIDs an address owns for a specific collection?
Like, I have the collection address and the user's address
How do I query the Blockchain to get the nftIDs that address owns?

u need to use a web3 library like web3 js or ethers js to query the blocc chain
and u need a node to actually communicate w/ the blocc chain
u can setup a node on ur computer which will take a day to download the entire blocc chain or you can sign up for an account at alchemy and use their nodes for free

Daa fu'c
I don't need something that complicated
I just need to know what function or a way to call some functions to get the data

Or Alchemy? Can they generate that data for me?

He don't need a node, he can just call the read function

o if u just want to read my bad
sending a txn much more involved
lol
but still

Yeah. I am looking at which read function to call
Cause so far, just ownerOf (which needs the nftID in which case I don't have)
And the balanceOf (which returns numeric number of NFTs owned, not the ID)

It's gonna be gasless
Yea, I got that up to this point
It's the actual function reading that I need help with

ur contract needs to be enumerable
https://docs.openzeppelin.com/contracts/4.x/api/token/erc721#IERC721Enumerable-tokenOfOwnerByIndex-address-uint256-
tokenOfOwnerByIndex(address owner, uint256 index) → uint256
and balanceOf(address owner) → uint256 balance
those 2 funds give u waht u need
use a 4 loop

Contract isn't mine
It's a Collection's contract
Like Bored Ape Yacht Club NFTs

Hmm 🤔
