How it works
- 01
Add your sources
A read-only key for Coinbase, Kraken or Binance, a wallet’s public address, or a file exported from another exchange. - 02
Maneta sorts your records
It reads everything, sorts out what it can and gives you a receipt: what was read, what was counted once, how values were found, and any questions for you. - 03
Answer, check, download
Answer the questions, read the report and what it rests on, then freeze it and download the figures for your Self Assessment.
Where your records can come from
- Coinbase · Kraken · Binance
- Bitcoin · Ethereum · XRP Ledger · Solana · Hedera · BNB Smart Chain · Polygon · Arbitrum One · Optimism
- Exchange export (CSV)
Most of it is handled.The rest is a short list
of questions.
Everything Maneta finds in your records ends one of three ways.
Maneta sorted it
You see a line in the receipt and in the log, with the reason. Undo is always there, and it survives the next sync.
- The same trade in two places is counted once
- Transfers between your own accounts are linked
- Missing values come from the source or from market prices
- Scam tokens, dust and address-poisoning attempts in your history are filtered out and listed, so they are never counted as yours.
Maneta has an answer; you check it
When Maneta cannot quite prove something, or a change would move your gain by a lot, you get one card to check before anything changes.
- Two records that look the same but cannot be proven the same
- A change that would move a year’s gain by more than £250
- A new transaction like one you answered before: “Same as before?”
Only you know
One plain question, with “I don’t know”, and a line saying what answering changes. Questions about the same thing are asked once, not twenty times.
- Whose wallet an address is
- Whether a transfer was a gift, a payment or a sale
- How a DeFi move or a fork should be treated
- What you paid for coins bought before your connected history
What Maneta never does
- Never invents what you paidIf a purchase is not in your records, Maneta does not guess a cost. The figures that rest on it read Unknown until you add the purchase.
- Never deletes a recordBoth copies of a duplicate are kept. One is counted.
- Never overrides your decisionWhat you decide stays decided, sync after sync. “These are different” is remembered for good.
- Never changes anything when you open a pageThe work happens when a source syncs or a file is imported, and ends with a receipt.
- Never signs or files for you“I confirm these figures” is always your own click. A report is frozen by you, or by your accountant’s firm when a Partner signs off a version. You file with HMRC yourself.
- Never moves fundsExchange keys are read-only. Wallets are added by their public address.
Figures,and what they
rest on.
The tax report shows the year’s gains and losses, then says in plain words what the figures depend on and what could still change them. A Draft can change. A report you freeze cannot.
Maneta only reads your records.
It never moves funds and never files for you.
- Exchange keys are read-only. Wallets are added by their public address.
- Both copies of a duplicate are kept. One is counted.
- “I confirm these figures” is always your own click. You file with HMRC yourself.
