Features / Imports

Connect your exchanges.
We handle the rest.

No more reformatting spreadsheets or manually entering prices. Import via API connection, CSV upload, or paste an on-chain wallet address — and get your HMRC calculation in minutes.

Live API connections to Binance, Coinbase, Kraken, and Bybit. CSV import supports every major exchange export format. On-chain import for Ethereum and Bitcoin wallets with historical GBP prices fetched automatically.

How imports work

Two ways to bring your data in

API connection

Connect your exchange account with a read-only API key. Your transaction history syncs automatically and stays up to date. We never ask for withdrawal permissions — we can only read.

  • Automatic sync — no manual exports
  • New transactions appear automatically
  • Read-only access — your funds stay safe
  • Set up in under 2 minutes

CSV upload

Export a transaction history file from your exchange and drag it in. We automatically detect the format and map the columns — no spreadsheet editing required.

  • Supports every major exchange format
  • Auto-detects columns and date formats
  • Works for older exchanges no longer active
  • Manual entry available for anything else

What we handle

Every transaction type, automatically recognised

We do not just import raw data. We understand what each transaction is and categorise it correctly for HMRC.

Spot trades

Buy and sell orders across all supported exchanges, correctly matched.

DeFi transactions

Swaps, liquidity provision, and yield farming automatically tagged.

Staking rewards

Recognised as income at the market value on the date received.

Mining income

Treated as income by HMRC — we calculate the correct pound value.

Airdrops

Classified correctly depending on whether they constitute income.

NFT trades

Purchases, sales, and minting events handled and categorised.

Transfer tracking

Moves between your own wallets are identified and not taxed as disposals.

Lost & stolen coins

Flag lost or stolen assets for correct HMRC treatment.

Margin & futures

Derivative positions handled with the correct gain and loss treatment.

Supported integrations

API, CSV, and on-chain
