How to send cash safely by mail for P2P cryptocurrency trading. Step-by-step packaging, postal service comparison, escrow options, and country-specific tips for Europe.
Cash by Mail (CBM) is a payment method for peer-to-peer (P2P) cryptocurrency trading where the buyer physically mails cash banknotes to the seller via postal service. The seller releases the cryptocurrency once they receive and verify the cash.
It was one of the most popular payment methods on LocalMonero (shut down May 2024) and AgoraDesk (shut down November 2024), where thousands of successful CBM trades were completed daily across Europe, North America, and beyond.
In 2026, Cash by Mail remains the primary method for buying Monero (XMR) without identity verification. The platforms have changed — Haveno, XMRBazaar, and OpenMonero have replaced LocalMonero — but the method itself is unchanged and proven over years of real-world use.
Proper packaging is the single most important factor in a successful CBM trade. Follow these steps every time:
1 Photograph everything. Before touching anything, photograph both sides of every banknote with your phone. Make sure serial numbers are legible. This is your proof of what was sent if anything goes wrong.
2 Record serial numbers. Write down or type out the serial number of every banknote. Store this separately from the photos (e.g., in a note on your phone). Serial numbers prove which specific bills were yours.
3 Wrap the cash. Wrap the banknotes in plain paper, carbon paper, or aluminum foil. This prevents the cash from being visible when the envelope is held up to a light, or through X-ray screening. The bills should be completely concealed.
4 Use a security envelope. Place the wrapped cash into an opaque, security-lined envelope. Many post offices sell special padded envelopes for valuables. Never use windowed envelopes, translucent envelopes, or thin paper envelopes.
5 Double-envelope (recommended). For extra security, seal the cash in an inner envelope first, then place that inside the outer mailing envelope. This adds a physical barrier and makes it harder for anyone to access the contents without visible tampering.
6 Seal thoroughly. Seal all edges and flaps with strong adhesive tape. Optionally, use tamper-evident tape or sign across the seal with a pen (so any opening would break your signature). Photograph the sealed envelope from all angles.
7 Send registered mail. Go to the post office (don’t use a mailbox). Send as registered mail (Einschreiben in German, recommandé in French, certificado in Spanish, raccomandata in Italian). Request signature on delivery. Keep the receipt with the tracking number.
8 Share the tracking number. Send the tracking number to your trading partner via encrypted messaging (Telegram, Signal, Session). Both parties can now monitor delivery in real time via the postal service’s tracking website.
9 Wait for confirmation. Once tracking shows delivery and the recipient confirms the amount matches, the crypto is released. With Haveno escrow, the seller clicks “confirm payment received” to release funds from the 2-of-3 multisig.
Here’s how registered mail works in major European countries:
| Country | Service Name | Insurance (default) | Delivery (domestic) | Tracking URL |
|---|---|---|---|---|
| Germany | Einschreiben Wert | Up to €500 | 1–2 days | deutschepost.de |
| France | Lettre recommandée | Up to €458 | 2–3 days | laposte.fr |
| Spain | Carta certificada | Up to €600 | 2–4 days | correos.es |
| Italy | Raccomandata con ricevuta | Up to €516 | 3–5 days | poste.it |
| Netherlands | Aangetekend verzenden | Up to €500 | 1–2 days | postnl.nl |
| Portugal | Correio registado | Up to €500 | 1–3 days | ctt.pt |
| Austria | Einschreiben | Up to €510 | 1–2 days | post.at |
| Belgium | Envoi recommandé | Up to €500 | 1–2 days | bpost.be |
| Switzerland | Einschreiben | Up to CHF 500 | 1 day | post.ch |
Escrow eliminates the trust problem in CBM trading. Instead of trusting that a stranger will send crypto after receiving your cash (or vice versa), a neutral mechanism holds the crypto until both sides are satisfied.
This makes scamming expensive. A scammer would lose their security deposit (5–15% of the trade), making it mathematically unprofitable to scam repeatedly.
| Platform | Escrow Type | Deposit | Fees |
|---|---|---|---|
| RetoSwap (Haveno) | 2-of-3 multisig | 15% | 0.6% |
| DawnSwap (Haveno) | 2-of-3 multisig | 5% | ~2% |
| XMRBazaar | Optional multisig | Varies | 0% |
| OpenMonero | Platform escrow | Varies | 0% |
For a detailed comparison of all four platforms, see the platform comparison page.
The number one mistake. Without tracking, you have zero proof that you sent anything, no evidence for dispute resolution, and no way to know if the package was delivered. Always use registered/tracked mail.
If a dispute arises and you can’t prove what you sent, you’ll lose. Photos of banknotes with visible serial numbers are your strongest evidence. Take them before wrapping, and again after wrapping (showing the sealed envelope).
Thin paper envelopes or windowed envelopes reveal the contents to anyone handling the mail. Use opaque, security-lined envelopes. If you can see the cash through the envelope when held up to a light, the packaging isn’t good enough.
Some traders prefer PO boxes for privacy, and that’s fine. But verify with your postal service that registered mail with signature requirement works for PO boxes in your country. In some countries, the recipient still needs to sign at the counter.
If you don’t know the person, use escrow. Period. Established traders with hundreds of completed trades may offer direct trades at slightly better rates, but for your first few trades, the security of escrow is worth the extra fee.
Don’t send €2,000 to someone you’ve never traded with before. Build trust incrementally. Start at €100–200, then €500, then €1,000+. Each successful trade reduces risk for both parties.
There is no universal legal limit on sending cash domestically within most EU countries. Key considerations:
| Factor | Cash by Mail | Bank Transfer (SEPA) |
|---|---|---|
| Speed | 2–8 days | Minutes to 1 day |
| Privacy | High (no digital trail) | Low (bank records everything) |
| Account freeze risk | None | High (banks flag crypto) |
| Chargeback risk | None (cash is final) | Possible (fraud claims) |
| Identity exposure | Minimal (postal address only) | Full (name, account, bank) |
| Availability | Anyone with a post office | Requires bank account |
| Premium | 5–15% over market | 2–8% over market |
| Escrow compatible | Yes (Haveno, XMRBazaar) | Yes (same platforms) |
| Regulatory risk | Low (no intermediary) | Growing (AMLR, MiCA) |
In 2026, banks across Europe are increasingly hostile to crypto-related transactions. Account freezes for SEPA transfers to known crypto platforms are common, even when the activity is entirely legal. Cash by Mail sidesteps this entirely — no bank is involved, no account can be frozen, and no transaction can be flagged.
Yes. Sending cash by mail is legal in most countries. Postal services offer specific insurance and tracking for valuables. Check your national postal service’s terms for specific limits. Within the EU, there are no domestic limits; cross-border amounts above €10,000 may require customs declaration.
Use opaque security envelopes, wrap bills in paper or carbon paper, use tamper-evident tape, and always send via registered/tracked mail with signature requirement. Photograph everything. Record serial numbers. The chain of custody created by registered mail is the strongest deterrent against theft.
Registered mail loss rates are below 0.1% in most EU countries. If it happens: file a claim with the postal service (tracking number + proof of contents), open a dispute if trading with escrow. Insurance covers declared value (typically up to €500 automatically).
Always registered (Einschreiben, recommandé, certificado). Registered mail provides signature on delivery, chain of custody, insurance, and legal proof. Standard tracked mail is acceptable for small amounts but lacks the full security chain.
Different trade-offs. CBM is safer from account freezes, chargebacks, and surveillance. Bank transfer is faster and has lower premiums. For privacy-conscious buyers, CBM is significantly safer because banks routinely flag crypto-related activity.
Yes. CBM is widely used in North America (USPS Registered Mail), UK (Royal Mail Special Delivery), Australia, and many other countries. The principles are the same: use tracked/insured registered mail, photograph everything, record serial numbers.
