On this page, we will introduce how to download transaction history from Coincheck.

1. Important Notes

• Please confirm the status of transaction history support on Coincheck.
  Cryptact's Support Status for coincheck

• Due to Coincheck's announcement that it will discontinue support for its own transaction history formats, cryptact has standardized its format support to the "Industry Standard Format" as of the April 3, 2025 update. Users who have previously used the "Trading History", "Reserve," or "Lending" files are now requested to upload their data using the "Industry Standard Format" file going forward.Please make sure to check for any duplicate entries that may occur due to the format switch. For example, if you have already uploaded your March 2025 transactions using the "Transaction History" file and then upload the March 2025 "Industry Standard Format" file, the same transactions may be counted twice.

• The industry standard format includes the same transaction history as found in the files for "Spot trade history," "Recurring buy," "Lending history," and "Cryptocurrency rewards history," Therefore, to prevent duplicate entries, if the industry standard format is uploaded, these four files cannot be uploaded individually. Please choose either to use the industry standard format or to upload these four files separately.
• Regarding the "Fee" field in the Transaction History file, although transaction fees are incurred, the field is left blank in the file, so they are not reflected in cryptact. On the other hand, the industry standard format includes transaction fees, which will be reflected when uploaded to cryptact. Therefore, we recommend uploading the industry standard format.

• In the Industry-wide Standard Format, both currencies paid/received for NFT transactions and the contract names of the NFTs are listed. Therefore, we reflect these transactions as swap trades. For NFTs, we automatically generate Custom coins based on the contract names listed in the file and reflect them in the cryptact.

• For NFT transactions (NFT Item Purchase/Purchased) in the "Trading History File", there is no information available to identify the specific NFT. Therefore, we process the cryptocurrency used/received for NFT transactions as follows.
  Please note that since there are no clear tax guidelines regarding NFTs, we recommend confirming the details with your local tax office.

  When the Operation is NFT Item Purchase/Purchased:

  If the Amount is positive: Treated as a purchase (acquired at fair market value)

• Regarding the purchase of cryptocurrency with points, it will be listed in the transaction history file as "Transaction Type: Other, Remarks: Point Exchange." We automatically treat this as acquisition at market value.

  However, using points for something typically requires recognition of income for the points used.

  However, this falls outside the scope of cryptocurrency profit and loss calculations.
  For cryptocurrency purchased with points, we kindly request that you apply the above treatment to calculate the average acquisition cost and subsequent profit or loss of the cryptocurrency.

  As for the recognition of income for points, we recommend handling it based on your own judgment, similar to how other point uses are treated.
