  1. 1

    Read

    Every transaction, internal transfer and token movement for the addresses you enter, straight from the chain.

  2. 2

    Price

    Each event valued at the hourly EUR quote. A swap takes its value from the native leg, the real consideration.

  3. 3

    Match

    FIFO per asset, self-transfers excluded, closing balance reconciled, country relief applied where it exists.

Counterfeit tokens never reach the calculation

Wallets get flooded with tokens whose ticker imitates a real one. Every highlighted character is not the letter it appears to be.

Gas is a disposal

Fees paid in crypto leave the pool at market value. Skipping them understates your deduction.

Balances checked against the chain

The closing pool is compared to the real address balance. A gap is shown, not hidden behind a total.

Relief computed per lot

Where a country grants a deemed acquisition cost, it is applied lot by lot, where the holding period lives.

Nothing is stored

No account, no database, no email. The result lives in your browser tab and goes with it.

What it covers

Pick Finland for the deemed acquisition cost (ITA 46.1), loss carry-forward (ITA 50) and the €1 000 small-disposal exemption (ITA 48.6), with FIFO per KHO 2024:123. Pick Generic FIFO for plain FIFO on actual cost, with no country relief claimed.

The method in full

What it does not

Trades inside an exchange account never touch the chain and must be filed separately. Mining, staking and airdrops are income, not disposals. NFTs are excluded. This is a calculation from public data, not tax advice.
