Cryptostamps

What is Cryptostamps

Cryptostamps is a cryptocurrency-powered postage platform operating in BETA since at least 2023. The service enables users to purchase USPS shipping labels without traditional payment methods or identity verification. As of 2026-05-30, the platform supports individual label creation, bulk CSV uploads up to 75 rows, and a "Magic Mode" that allows pasting up to 15 addresses for rapid domestic USPS label generation.

The service explicitly markets itself with "No javascript" on its homepage-a notable privacy and security choice that reduces browser fingerprinting and potential attack surfaces. The footer on every page advertises a Tor onion address and dark.fail verification link, signaling deliberate outreach to privacy-conscious users.

How no-KYC is it?

Cryptostamps appears genuinely no-KYC. Account creation requires only a username, password (minimum 10 characters with complexity requirements), and CAPTCHA verification. No email address, phone number, government ID, or physical address verification is requested during signup. This represents a minimal-barrier entry point compared to mainstream postage platforms that universally require credit cards and billing addresses tied to real-world identity.

The service does not appear to implement tiered verification levels. All functionality appears accessible immediately upon account creation, with no evident limits that escalate based on identity disclosure.

Privacy & security

Cryptostamps implements several privacy-focused design choices. The "No javascript" homepage claim holds for the main landing page, though logged-in functionality likely requires JavaScript for the label creation interface. Support operates through a ProtonMail Plus address (support@cryptostamps.biz), and a PGP public key is published for encrypted communications. The Tor onion service and dark.fail listing provide additional anonymity layers for access.

The platform's operational security posture includes standard password complexity requirements. However, the BETA status and lack of detailed security documentation-no bug bounty program, no penetration test results, no formal security audit-is evident. The .biz domain and estimated low traffic (per third-party analysis) mean limited independent scrutiny compared to established services.

Notably, UPS shipments are temporarily disabled as of the 2026-05-30 crawl, with the site stating "We are working to resolve an issue with this provider." This operational limitation reduces carrier options to USPS exclusively for the moment.

Payments, fees & limits

Cryptostamps accepts six cryptocurrencies: Monero (XMR), Tether (USDT), Bitcoin (BTC), Ethereum (ETH), Bitcoin Cash (BCH), and Litecoin (LTC). Monero's inclusion is particularly significant for privacy-conscious users seeking untraceable payments.

Pricing is denominated in USD with real-time cryptocurrency conversion at checkout. The refund policy (last updated December 19, 2023) states that unused postage qualifies for full refund in original currency within 48 hours, subject to shipping partner approval. Refunds can take multiple weeks and may have network fees deducted. Completed cryptocurrency exchanges are non-refundable unless processing exceeds 12 hours.

Specific fee schedules are not publicly displayed; users see final prices during label creation. The CSV bulk tool caps at 75 shipments per upload. Magic Mode currently supports domestic USPS only, with international requiring direct support contact.

User experience & support

The interface is utilitarian and function-first. Three workflow options accommodate different shipping volumes:

• Standard single-label creation with dimensional input
• Magic Bulk: paste-mode for up to 15 domestic packages with uniform dimensions
• CSV Bulk: spreadsheet import supporting 75 rows with per-package customization

USPS service options include Priority, Express, GroundAdvantage (replacing deprecated First/Parcel Select per a site notice), LibraryMail, MediaMail, and international variants. Package types span letters through Large Flat Rate Boxes.

Support availability is advertised as "24/7" via the ProtonMail address. No live chat, phone support, or ticket system is evident. The bilingual English/Spanish interface broadens accessibility.

Who it's for

Cryptostamps suits privacy-focused individuals and small businesses needing USPS postage without financial surveillance. Monero users benefit from payment unlinkability. Bulk shippers appreciate the CSV and paste tools, though the 75-row cap and domestic-only Magic Mode limit enterprise scale. The BETA status and single-carrier operation (with UPS disabled) make it best suited for non-critical shipments where users accept some operational risk in exchange for anonymity.
