Track transactions after an exchange shutdown, bankruptcy, or API loss

When an exchange shuts down, files for bankruptcy, or stops providing API access, you can still keep its transaction history in CoinTracker. How you handle it depends on whether your transactions are already in your account.

Transactions already synced to CoinTracker

If you previously connected the exchange to CoinTracker, archive the account. Archiving sets the reported balance to $0, stops sync attempts, and preserves your full transaction history and cost basis for taxes. For step-by-step instructions, see how to archive a wallet or exchange.

CoinTracker automatically applies a defunct state to known bankrupt or shut-down exchanges, including BlockFi, Celsius, FTX, Genesis, Mt. Gox, and Voyager. If your exchange is in this list, you don't need to take any action — the account is already marked defunct. For more details, see why your exchange is marked as defunct.

Important: Don't remove the exchange to "clean it up." Removing a wallet or exchange permanently deletes its transaction history, including any manual edits, and can break your cost basis calculations.

Your transactions aren't in CoinTracker yet

If you never synced the exchange to CoinTracker, import its transaction history from a CSV file.

Step 1: Download your transaction history

  1. Sign in to your exchange account (if you still have access).
  2. Navigate to the section where you can export your transaction history. This may be labeled Reports, Transaction History, or Trade History.
  3. Download the CSV file with your complete transaction history.

If the exchange is completely shut down and CSV downloads aren’t available, reconstruct your transaction history using personal records, emails, or by cross-checking with your backup file. 

Step 2: Upload your CSV to CoinTracker

  1. Navigate to the Wallets page.
  2. Select + Add wallet.
  3. Enter the exchange's name to upload its CSV, or enter CSV to upload a CoinTracker-formatted CSV.
  4. Select the file and select Import.

If you run into any issues while trying to import your CSV: 

Step 3: Review and reconcile transactions

After import, review your transactions for accuracy:

  • Compare balances with your records.
  • Check for missing transactions.
  • Adjust cost basis if needed.

If you find discrepancies, cross-check with your backup file, exchange statements, or email confirmations.

Handle special cases

Multiple-year CSV files

If your exchange provides separate CSV files for each year, make sure you import them into the same wallet, one file at a time. 

Bankruptcy cases 

For US customers: If an exchange has filed for bankruptcy, the value of assets held on the platform may be uncertain and might need to be categorized as lost funds. Learn more about how to handle bankrupt exchanges.

Tracking stuck or unavailable funds 

For US customers: If your assets are inaccessible but not necessarily lost, label them appropriately in CoinTracker for tax reporting. For more on handling lost, stolen, or worthless cryptocurrency, see the lost, stolen, or worthless cryptocurrency guide.

Migrating to a new exchange 

If you've moved to a new platform, add the exchange to your account to keep tracking transactions. This ensures your CoinTracker account stays up to date.

Left a supported region

If you're now in a region the exchange doesn't support, you can reach out to that exchange's support team and request historical transaction data.
