This is what you should keep in mind for deposits that you cannot explain.
November 12, 2026
On native blockchains such as Ethereum or BSC, it can happen that you have received deposits that you did not make yourself. These are often tokens that were given to you by strangers for advertising purposes or for fraudulent reasons.
Often, the value of these tokens is not known because of missing data and knowledge via the CoinmarketCap / CoinGecko interface. Unfortunately, there is no way to distinguish the unknown tokens from intended deposits.
One possible way to deal with this is to delete these deposit transactions.
Or, if you want to declare them, you can mark them as an airdrop. For tax purposes, chain.report would treat these deposits as an airdrop, whereby the inflow is likewise not treated as taxable by chain.report. Please be careful, however, if you dispose of these tokens. chain.report would then treat this disposal as taxable, and in this case you should not delete the corresponding transactions.
If you cannot clearly identify the error or its cause:
Example: The tax burden is too high, but you do not know exactly why?
Example: You cannot resolve warnings?
Example: There are balance discrepancies in the wallets.
