Idea: Zcash Prepaid Voucher — A Paysafecard-Style System for Private Onboarding

Here my idea for discussion (AI summary):

:magnifying_glass_tilted_left: What is Paysafecard?

Paysafecard is a widely used prepaid payment method that allows users to pay online without a bank account or credit card. Here’s how it works:

  1. The user buys a physical or digital voucher (typically a receipt with a 16-digit PIN) at a retail location — such as a gas station, supermarket, or kiosk — using cash.
  2. The PIN represents a fixed monetary value (e.g. €10, €25, €50).
  3. This code can be entered on supported websites to pay anonymously — no bank details or identity required.

:white_check_mark: Main value: cash-to-digital payment onboarding without identity exposure.


:repeat_button: How could this work with Zcash?

Zcash already allows shielded transactions, which protect the sender, receiver, and amount. However, onboarding into ZEC typically requires:

  • A crypto exchange account (with KYC),
  • A bank connection,
  • Technical knowledge of wallets and seed phrases.

A “Zcash voucher” system would bridge this gap by allowing users to buy ZEC with cash, in a manner similar to Paysafecard — and then spend or store it privately.


:brick: Two Implementations: White-Label vs. Fully Decentralized


:green_circle: Option 1: White-Label ZEC Voucher via Retail Partners

:puzzle_piece: Overview:

  • Partner with an existing voucher/payment infrastructure (e.g. Funanga, InComm, epay, etc.).
  • These partners already allow users to:
    • Generate online codes,
    • Pay in-store with cash,
    • Redeem the code online (often for BTC or gift cards).
  • Zcash would be integrated as a new redemption option.

:hammer_and_wrench: How it works:

  1. User generates a voucher code (or buys one directly in-store).
  2. Pays with cash at a retail partner.
  3. The backend system marks the code as “funded.”
  4. The user visits a redemption site and enters the code + a ZEC address.
  5. The system sends the equivalent ZEC (ideally as a shielded transfer) to the user.

:white_check_mark: Pros:

  • Fast to scale (thousands of physical retail points already exist).
  • Legal under existing prepaid voucher frameworks.
  • Great UX for mainstream users.

:red_exclamation_mark: Cons:

  • Requires integration with centralized financial services.
  • Might involve regulatory frictions (e.g., AML limits).
  • Trust needed in the issuing entity.

:orange_circle: Option 2: Fully Decentralized ZEC Voucher Protocol

:puzzle_piece: Overview:

  • No trusted intermediaries.
  • Anyone can generate a ZEC voucher code representing a shielded output.
  • Codes are optionally encrypted and may be printed, stored as QR, or even gifted.

:hammer_and_wrench: How it works:

  1. A user (or merchant) loads ZEC into a shielded address.
  2. The note is associated with a one-time redeemable code (e.g., encrypted key data, or a reference to a withdrawal service).
  3. Another user receives the code and uses it to:
  • Redeem to their own wallet,
  • Spend it via a service,
  • Or transfer it further without ever revealing their identity.

This could be run as a P2P marketplace, or wallet-to-wallet gifting system.

:white_check_mark: Pros:

  • No KYC or central party.
  • Aligns with Zcash’s core mission of private financial freedom.
  • Can function as a grassroots, global remittance and tipping tool.

:red_exclamation_mark: Cons:

  • Requires robust UX to manage codes securely.
  • Fraud protection and “burned code” prevention is tricky without a coordinating entity.
  • No refund or recourse if the code is lost or double-spent.

:rocket: Why this Matters

  • Shielded transactions are powerful — but access to them is still too gated.
  • We need a way to bring physical cash into private crypto, especially in:
    • Underbanked regions,
    • Oppressive regimes,
    • Cash-heavy cultures.

A Zcash voucher system would give users access to:

  • True financial privacy from the moment of entry,
  • A giftable, offline-compatible crypto experience,
  • A way to scale adoption without needing centralized exchanges or wallets.

What do you think about this idea is it feasible, interesting, etc? I am happy about your feedback.
