Integrity proof for strategy audits

Verify the report, not the screenshot.

A “Verified by Quantor” audit is useful only when anyone can check the exact JSON and its Ed25519 signature. Paste both files here: the emerald seal appears only when the signature matches Quantor’s published key and the report has not been changed.

What counts as proof here: only a report that passes the cryptographic signature check on this page, or via openssl with our published key. A screenshot, PDF, or video of a report proves nothing: pixels can be edited by anyone. Free previews are unsigned and always carry a “PREVIEW - UNSIGNED” watermark. They never verify.

How verification works

Get your strategy verified:

Export your trade log as a CSV from Binance, Bybit, 3Commas, Cornix, TradingView, MT4/MT5, or a custom sheet. It needs a header row plus either a PnL column or entry + exit + qty columns.
Upload it below and get a free unsigned preview instantly. It runs from the file only: no API keys, no account access, no signup. Limits: 4 MB / 100k rows.
Want it signed? Pay $99 with a card or PayPal balance on this page when checkout is available, otherwise by invoice. We reply within 24-48 h.
You receive an evidence bundle: signed report JSON, Ed25519 signature, your original CSV unchanged, and the offline verification recipe. Paying on the page, that download appears the moment the payment clears.

Check someone’s claim:

Ask for both files: the report JSON and the signature. A screenshot is not a report.
Paste them above. The emerald seal appears only if the signature matches our published key. Any edit to a single character makes it fail.
Prefer not to trust this site? Verify offline with stock OpenSSL:

« save the report EXACTLY as received to report.json and the signature to sig.b64 »
base64 -d sig.b64 > sig.bin
curl -s https://quantorsaas.app/api/v1/public/audit/verify-key \
  | jq -r '"-----BEGIN PUBLIC KEY-----\n"+.publicKeyBase64+"\n-----END PUBLIC KEY-----"' > quantor.pem
openssl pkeyutl -verify -pubin -inkey quantor.pem -rawin -in report.json -sigfile sig.bin
# → "Signature Verified Successfully"

Scope: verification proves the report was produced by Quantor’s audit engine from the submitted trade log and was not altered afterwards, with costs applied at honest floors. It does not prove the strategy is profitable going forward, and it does not by itself prove the trades were executed on an exchange. It makes the presented record tamper-evident and checkable, losses included.

Trader workflow

Run a free unsigned preview

Upload or paste a trade-log CSV. The audit runs from the file only: no API keys, no account access, no signup. The preview helps you catch wrong columns before paying.

CSV format

Example:

symbol,side,qty,entry,exit,closeTime
BTC/USDT,LONG,0.05,42000,44500,2026-01-05T00:00:00Z
BTC/USDT,LONG,0.05,44800,43900,2026-01-11T00:00:00Z
ETH/USDT,SHORT,0.8,2460,2280,2026-01-26T00:00:00Z

Accepted: comma, semicolon, or tab separators; Excel UTF-8 BOM and Windows line endings; one closed trade per line; 4 MB and 100,000 row limits.

Required columns: either a PnL value, or entry + exit + qty with a recognised side. Column names are matched case-insensitively, with spaces and underscores ignored.

Not accepted: screenshots, PDFs, XLSX files, open positions, percent-only PnL, accounting negatives, space thousands separators, or fill-level exports where one trade spans many rows. Skipped rows are disclosed, never guessed.

Why can't I verify this? Because it is not signed, and that is the point. If a free preview could pass verification, anyone could pass one off as an audited record and the seal would mean nothing. Only the paid report carries an Ed25519 signature, and only it shows the seal and verifies on this page or with openssl. See what a signed report looks like

One-time signed audit

Get it signed - Verified by Quantor · $99

The preview above is unsigned: anyone could edit it. The signed audit turns your record into an Ed25519-signed verification report with a public verify link anyone can check independently. One strategy, any platform. No signup: we never see an account of yours, only the file you upload.

Signed report cryptographically bound to the SHA-256 of your exact CSV. Nothing can be edited, deleted, or back-dated without breaking the signature.
Public verify link on this page, plus verification with one OpenSSL command against our published key.
Same honest engine as this preview: realistic cost floors, skipped rows disclosed, losses included.
Delivered as a ZIP bundle: report, signature, your original CSV, and the three-command OpenSSL recipe.
Your trade list stays private by default. The report carries totals and the SHA-256 of your file, not your entries. Ask for the full version if you want the trades listed.

After paying: send your trade-log CSV to support@quantorsaas.app or attach it to the payment note. We return the signed report and its public verify link within 24-48 h. If your file turns out not to be auditable, we refund in full: you risk nothing by paying first.

We verify the integrity of your records. We do not verify profitability, rate the strategy, or establish where the data came from.

A successful check proves the report was signed by Quantor’s audit key and has not been altered since. It does not prove the supplied trades are real, nor predict future performance. For fully independent verification, fetch the public key at /api/v1/public/audit/verify-key and check the Ed25519 signature over the exact JSON bytes with any tool.
