如何在 BSC 上获取合约的所有持有者

Question

How do I get contract's all holders with balances on BSC network?

• From bscsan.com you can export only top holders in CSV format
• From bitquery there's no ready method for holders. There's transfers, senders, receivers etc.. I guess you could solve the holders list somehow from this data but didn't find any example
• CovalentHQ's API has a method for this, but unfortunately it's giving timeout error if the holders list for the contract is huge (like SafeMoon with >1.7M holders). I asked their support for solution, but I guess they gave up because they stopped responding
• My latest plan was to use ethereum-etl. This was showing promise and found an article about it . It seems I need to get traces and transactions to be able to query for balances. But when I tried to load the traces:

ethereumetl export_traces --start-block 0 --end-block 500000 --provider-uri https://bsc-dataseed1.ninicoin.io --batch-size 100 --output traces.csv

I get following error message:

ValueError: {'code': -32601, 'message': 'the method trace_block does not exist/is not available'}

This made me think that maybe the tool does not support BSC.

So any ideas? Have been banging my head to the wall for couple days now.

CovalentHQ's API has paging built into it. You could call it for each page of 1000 results and append each page to a file using python.
