Topic: Check the balance of 1 million ethereum/BNB/MATIC addresses (Read 109 times)

Hello ! I hope you are all well

I had a question, most likely someone has already commented or mentioned the topic but I haven't found anything.

I have a text file with 1 million ethereum addresses 1 on each line

I would like to know if any of those addresses have had more than 1 transaction in the ETH BNB OR MATIC network or if any of the addresses have a balance greater than 0 in ETH BNB OR MATIC, whichever works faster
 
I currently use the blockchain, moralis and ethscan API, but when checking 100,000 or 150,000 addresses, the script stops, and since it is not saved, I have to access the text file manually, select the last scanned line and delete from that line to the first to do not check the same addresses again

I have also tried a code from javascript that checks the addresses here: https://blockscan.com/address/0x98f39d0f8c67885071cc99c5af1d4cacbcc89b0c?t=tx
 where does 0x98f39d0f8c67885071cc99c5af1d4cacbcc89b0c go try the ethereum.txt addresses
If the result is: Your search - {0} did not match any tx hash. - means that that address HAS 0 TRANSACTIONS
If the result is different, it means that that address has more than 1 transaction, that code also works correctly but since it is through http, every 1000 wallets checked you have to wait a minute to continue checking more and it is very slow


Any help is appreciated!!
