Step 1: Connecting Your Wallets & Exchanges

 

Connecting Your Wallets and Exchanges

Getting your transactions sorted out can feel like a mountain to climb, but Stuart and our dedicated team are right here to help you get through it smoothly. Using the BitTax Kryptos Package, our main goal in this first step is to pull together your complete trading history safely, securely, and with as little fuss as possible. By gathering this data, our platform can handle the heavy lifting of figuring out your exact capital gains or income for HMRC, meaning you can skip the nightmare of manual spreadsheets altogether.

We always recommend establishing direct, read-only connections with your exchanges whenever you can because it keeps your history continuously updated and perfectly accurate. Remember, your security is our absolute priority; these connections never give anyone access to your actual funds. If you ever run into a question or feel stuck at any point, our AI helper Bitty is always ready to jump in, or she can pass you straight through to Stuart and our human support team for some personal guidance.

Direct API Syncing

This is by far the most straightforward and automated way to bring your transaction history into the BitTax Kryptos Package. An API functions as a secure, completely read-only data bridge between your chosen exchange and our tax platform. It grants the system permission to view and import your trading history, completely free from any ability to touch, trade, or withdraw your actual crypto assets.

To establish this link, you simply log into your exchange on a web browser, locate their account security settings, and generate a new API key. The most vital step here is ensuring that only the "Read" or "View" permission boxes are ticked, while leaving withdrawal and trading permissions completely disabled. Once you copy and paste that key and its accompanying secret code into our software, the dashboard pulls your historical data and stays updated automatically.

Public Wallet Addresses

If you prefer keeping your digital assets off exchanges in self-custody wallets, you will connect them using your public wallet address. Your public address acts very much like a traditional bank account number or an IBAN; it is completely safe to share because it only identifies your account on the public ledger and never exposes your private keys or seed phrases.

To sync a private wallet, simply copy your public address or public key from your wallet interface. Paste this address into the wallet connection area of the BitTax Kryptos Package, making sure to select the correct blockchain network. The software then instantly reads the public ledger entries associated with that address to build a clean, accurate timeline of your transaction history.

CSV File Uploads

For older or closed exchange accounts, or for platforms that do not offer automated API bridges, CSV file uploads are your go-to solution. A CSV file is a standard spreadsheet format that contains a chronological, line-by-line log of all your historic purchases, sales, deposits, and withdrawals.

To use this method, you log into your crypto platform and request a download of your complete transaction history in an Excel or CSV format. Once the file is saved to your computer, you simply upload it directly into the matching data section inside the BitTax Kryptos Package. Our system reads the rows, maps out the assets, and blends them seamlessly into your overall portfolio calculations.

🔒 Frequently Asked Questions

  • Is it safe to give the software access to my exchanges through APIs?
    Yes, because you are only enabling read-only permissions, which means the platform can only view transaction data and has zero capacity to touch or move your funds.
  • What happens if one of my old crypto exchanges has gone out of business?
    You can manually upload any historic CSV files or account statements you exported and saved before the platform shut down.
  • How far back into the past do I need to link my crypto history?
    You should sync your data all the way back to your very first crypto transaction so the software can calculate your exact asset cost basis accurately.
  • Why does my wallet balance look slightly incorrect after finishing the sync?
    This usually means a specific blockchain network was accidentally left out during setup, or an early transaction from an exchange is missing.
  • Does the software ever see or store my private keys or seed phrases?
    No, the platform never interacts with, asks for, or stores your private keys or master recovery phrases.
  • What should I do if an exchange API fails to pull all my old data?
    If an API connection times out or restricts very old data, you can fill in the missing history by uploading a CSV statement from that platform.
  • Do I have to report simple transfers between my own personal wallets?
    Moving crypto between your own accounts is not a taxable event, but these transfers must be logged so the software knows you didn't sell the asset.
  • How does the software handle blockchain gas fees and network costs?
    The system automatically tags network and gas fees, applying them to reduce your capital gains where permitted under HMRC rules.
  • Can I manually adjust a transaction if the imported data looks wrong?
    Yes, the dashboard gives you full control to manually review, edit, or change tags on individual transactions to keep everything perfectly accurate.
  • What should I do if an exchange I use isn't listed in the software?
    You can easily download our universal custom CSV template, format your data to match the columns, and upload it right into the main dashboard.
