XDC Balance of an Account does not match with Address

[bmalepaty]

I checked an Address https://xdcscan.io/address/0xd77875dF9C9dE07a5a701F4431743e3A0e9Fe03a, which has 12 debit transactions that sum up to -6730003000 (Negative due to all debit transactions). But explorer balance shows 14,046,000,699 XDC.
Can you please explain this discrepancy. Is it due to genesis balance? If yes, where can we find the list or API of all addresses and their genesis balances.

I checked the address’s balance in the genesis block, and it wasn’t pre-allocated. The issue is with transactions after block 61171073, which may be related to internal transactions.

But this address does not have any internal transactions

During the interaction with the contract 0x802ad609f16ad1b8aeb58d93350246bb8869b75a, a transfer of tokens occurred, which was not recorded by XDCScan. Below is the detailed information of the token transfers:

Block	Balance (Before)	Decreased Value	Balance (After)
50829323	14950000899	100	14950000799

72539920	14169000600	122999900	14046000700

The total value of tokens transferred is 230,999,899 XDC, whereas the total amount shown by XDCScan is 673,000,300 XDC.

Before Block 50829323, your balance was 14,950,000,899 XDC. Subtracting the total transferred amount (230,999,899 XDC) and the amount shown on XDCScan (673,000,300 XDC), leaves a balance of 14,046,000,700 XDC. After accounting for the gas fees incurred during these transactions, this matches your current account balance.

I hope this helps. If you need any additional details about the transactions, please let me know！

Thanks @JukLee0ira. Is there any Explorer or RPC APIs that give us the above data you shared. We need to validate a bunch of addresses, and APIs if any would help

[gzliudan]

You can try SubQuery. Maybe it has such API.

[bmalepaty]

Also, you mentioned Balance(Before) blocknumber 50829323 to be 14950000899. How can we get this data? As per explorer this seems to be first debit transaction of the address. The first transaction only causes a negative balance.
Can you also provide more details on how you obtained the above information. We have the node syncing, and can retrieve any data from node too.

[JukLee0ira]

Actually I wrote a script to query this data, but I'm not sure if it’s suitable for enterprise-level production environments.
