paid report · ships at the 2027 filing season

The check proves it. The report hands it over.

The free check proves the number is right — recomputed fill by fill, verified on two independent axes. The paid report hands over the record behind the number: every disposal as an evidenced row, in the formats a filing workflow consumes — while every classification decision stays with you and your preparer.

01

Per-fill evidence ledger

Every number in the report decomposes to the fills behind it — timestamp, market, side, closed PnL, signed fee, trade id. Nothing is asserted without the rows that produce it.

02

Cost basis tracking

FIFO and weighted-average lot tracking across the reconstructed history, so disposals carry an actual basis instead of a guess — under the method you and your preparer choose.

03

CEX basis chain

Exchange CSV imports (Kraken, Coinbase) matched against venue deposits and withdrawals — basis follows the transfer chain onto the venue instead of resetting to zero.

04

Form 8949-format export

Dispositions, proceeds, basis and gain/loss laid out in the columns Form 8949 uses — the rows your filing workflow or preparer consumes. CSV and PDF.

05

Multi-address merge

Sub-accounts and secondary wallets reconciled together, with internal transfers netted out instead of double-counted.

06

Persistent, refreshable report

Your report lives at a stable link and re-verifies on demand as new history lands — the free check recomputes and forgets; the report keeps the evidence.

what the report is not — in writing

  • — The report is recomputation plus evidence — it is not a filed return, not an audit, and not tax advice.
  • — Classification stays with you. What counts as income, which basis method applies, how funding is treated — those are filing decisions for you and your preparer. The report computes and evidences; it doesn't decide.
  • — One venue per report. Hyperliquid today; the method extends to other perp venues on the same evidence standard.
  • — Builder-dex accounts: where the venue's own series contradict each other, the report prints the measured divergence in the disclosure annex — it does not pick one silently.
  • — Cost basis depends on the history you feed it. Missing exchange exports produce flagged gaps, not invented basis.
