We are using the API provided by etherscan.io and ethplorer.io in order to import Ethereum Wallet related transactions. These are the best and most reliable APIs on the market. However we are only able to import what they provide over the interface. So unfortunately not all tokens are supported yet and there are some requirements to fulfill, before they list tokens in their API. Also no "Internal Transactions" are being imported by this API provider for the Ethereum Wallet import.


In some cases it is necessary to enter the data manually by yourself. It's easy to find this data on Blockexplorers like etherscan.io.

 

Failed Transactions also not imported via API, but the fees have been deducted from the balance. They have to be added manually as transaction type "lost".
Once all the missing data added, the balance is correct within your ETH wallet.


You are able to enter missing transactions either manually on the Enter Coins page, with the Excel Import, or with the Custom Exchange Import. 


In addition we provide CSV imports for some software/online wallets (e.g. Trezor, Exodus, Electrum etc.).
