Hi, I hope its not out of topic.
I need the list of all owners from specific NFT collections, is there a way to export them somehow? Example: all wallets that ever bought or had any of Cryptopunk NFTs

Technically yes.

Is there a tutorial or guide how to get all addresses that ever owned an item from a specific collection?

Sorry if I'm just repeating, I meant to ask if you know where can I learn more about this. Currently getting all addresses manually from etherscan and it takes years to process all

Learn to use etherscan api wisely, then you'll be able to do whatever you want

Manually? Etherscan has api, you can request 10000 txs per call

I never checjed how APIs work, but I'll get into it. Thanks buddy

You're welcome :) there are also user friendly solutions like https://github.com/EtWnn/ScanWatch if you work wih python but you'll get bloated by their sqlite database that stores all the transactions you're retrieving

but it uses bscscan api

if bscscan server is down ==> api will be down

How would you bypass bsc/eth/polyscan otherwise? 😅

Simply query the chain with a script

choose an endpoint and check for what you need

no UI maybe but at least it works

By querying the chain you have to do more work though, for instance if I'm looking for a BAYC txs I need to loop through all the blocks and the txs in each block to find them

Lots of computational complexity. Those api are centralized but they already do all the hard work 😅

then wait for etherscan

depends what you need

if you have the tx like our friend case before

It is so easy to check the status

If you have the txs yeah, you're right, I was talking about finding the txs

what do you think bscscan does?

In fact you can use bscscan api to find the txs, that was what I was saying

Maybe you're saying to just use both

nono I mean that if bscscan doesn't work
maybe neither their api do

Aaaaaah well yeah, but... it is down right now? Lol I just checked

Check if this helps

Wow I'll have a deep look at it, thank you :D
