P2P evidence checklist: what to save before, during and after a trade

A printable checklist of the evidence that decides P2P disputes: counterparty vetting, the order trail, payment proofs and dossier assembly after a freeze. Bona fide sellers lose triangulation cases not on facts but on missing screenshots. Free and open — no email gate.

The checklist

Four sections, copy and keep. Items in section 1–2 are per-trade habits; sections 3–4 activate after an incident.

Section 1 — before the trade. Everything here costs under a minute and prevents the majority of disputes outright.

P2P EVIDENCE CHECKLIST — 1. BEFORE THE TRADE (prevention)
[ ] Counterparty profile screenshot: rating, completed orders,
    registration date, total volume
[ ] Payer name on the incoming payment = counterparty's verified name
    (third-party payment -> cancel the order, no exceptions)
[ ] Chat stays on the platform; any move to Telegram/WhatsApp is captured
    as a screenshot (going off-platform = classic scam setup)
[ ] Your own deposit addresses pass a USDT blacklist / AML check

Section 2 — during the trade. The order page, the chat and the payment receipt are the triangle that proves good faith. Release only after money is confirmed in your own bank app.

P2P EVIDENCE CHECKLIST — 2. DURING THE TRADE
[ ] Full order page: order ID, asset, amount, rate, timestamps
[ ] Entire platform chat with the counterparty (scroll-through screenshots)
[ ] Incoming payment receipt: payer name, exact amount, date and time
[ ] Match: payment amount and reference == order amount
[ ] Crypto release TxID after payment is confirmed in YOUR bank app
    (never release on a payment "screenshot" alone)

Section 3 — after a freeze or complaint. Evidence first, emotions later: notices, case numbers, full P2P history export, your trader statistics.

P2P EVIDENCE CHECKLIST — 3. AFTER A FREEZE / COMPLAINT
[ ] Bank letter or in-app notice: date, stated reason, reference number
[ ] Exchange notice: which account function is restricted, case number
[ ] Export of your full P2P history on the platform (CSV or screenshots)
[ ] Your trader statistics: completion rate, volume, account age
[ ] All of the above for THE disputed order collected into one folder

Section 4 — dossier assembly. Named annexes plus a one-page cover note. An officer who can navigate your folder in one minute is an officer on your side.

P2P EVIDENCE CHECKLIST — 4. DOSSIER ASSEMBLY
[ ] Files renamed: Annex_01_order.png, Annex_02_chat.pdf,
    Annex_03_payment.pdf, Annex_04_txid.txt …
[ ] One-page cover note: who you are, the disputed order in 3 sentences,
    list of annexes (use our compliance-response template)
[ ] Copies stored outside the exchange account (cloud + local)
[ ] Nothing deleted: accounts, orders and chats stay untouched —
    they are evidence, not liability

Usage rules

1. Screenshots must include the device clock and the platform UI — cropped fragments prove little.
2. Store copies outside the exchange: account access may be restricted exactly when you need the evidence most.
3. The payer-name check is absolute: name on the payment ≠ verified counterparty name means cancel, whatever the explanation in chat.
4. Run your own deposit addresses through a blacklist check periodically — your counterparties' risk becomes yours.

What NOT to do

• Do not delete orders, chats or the account after an incident — that is the evidence base, not the liability.
• Do not refund a "victim" outside bank/platform procedure — an undocumented refund reads as an admission.
• Do not keep trading on an account already under a complaint — new orders add new counterparty risk to an open case.

What Onyx does in your case

1. Forensic report on your addresses (Chainalysis/TRM class): what exactly triggered the flag and your real distance from the risk cluster.
2. Source of Funds dossier — a chronological reconstruction of your capital with documents, in the format compliance actually reads.
3. Communication with the platform's compliance or your bank — one verified position instead of ticket chaos.
