Buy Gift Cards with Zcash — zk-SNARK Shielded Transactions, No KYC
Genghis accepts Zcash (ZEC) at checkout — pay from a transparent (t-address) or shielded (z-address) wallet. Zcash uses zk-SNARK zero-knowledge proofs (Halo 2, no trusted setup) to shield sender, recipient, and amount on shielded-pool transactions. Spend ZEC on 4,300+ gift cards, game keys, and eSIMs across 80+ countries. Block time 75 seconds; fees ~$0.0001. Zero KYC. Zero platform fees.
Why pay with Zcash on Genghis?
Zcash is the privacy chain built on academic cryptography. zk-SNARK zero-knowledge proofs let the network verify transaction validity — that no value was created or destroyed, that the sender owns the funds, that signatures check out — without revealing any of the underlying data. The math is some of the most rigorously peer-reviewed work in modern cryptography, originating from research at MIT, Johns Hopkins, Tel Aviv University, and the Technion.
For digital-goods checkout, Zcash offers a property no other chain matches: selective privacy. You choose, per transaction, whether to send from a transparent address (t-address, behaves like Bitcoin) or a shielded address (z-address, fully private under zk-SNARKs). For users who want optional privacy — private when it matters, transparent when it doesn't, occasionally both at the same time via the t-to-z and z-to-t flows — Zcash is the only major chain offering that flexibility cleanly.
Since the NU5 network upgrade and the move to Halo 2, Zcash's shielded protocol no longer requires the original trusted-setup ceremony. The zero-knowledge proofs are now generated and verified without any ceremony parameters, eliminating one of the most-cited objections to early Zcash. Combined with the NU6 upgrade and Orchard pool, the modern Zcash protocol is cryptographically clean and operationally mature.
How to buy gift cards with Zcash: 3-step checkout
- 1
Pick your product
Browse 4,300+ gift cards, game keys, eSIMs, and prepaid cards. Add to cart. No account creation required.
- 2
Select Zcash at checkout
Click "Pay with crypto" → choose ZEC. The deposit screen shows a deposit address — by default a transparent address for processor compatibility — and the amount in ZEC locked at the current rate.
- 3
Send and receive
Send the displayed amount from your Zcash wallet (Zashi, Ywallet, Nighthawk, Edge). You can pay from either a transparent or shielded address — Zcash handles the conversion at the protocol level. After 1 confirmation (~75 seconds) Genghis dispatches your code.
Total time from click to code is typically 2–4 minutes. If you pay from a z-address, your sender address is shielded — Genghis sees the value arrive but not the source. If you pay from a t-address, the transaction is publicly visible like a Bitcoin transfer. Choose based on your privacy needs.
How zk-SNARKs make Zcash transactions private
zk-SNARK stands for zero-knowledge succinct non-interactive argument of knowledge. In plain English: a way for one party to prove a statement is true to another party, without revealing why it is true and without back-and-forth interaction.
Applied to Zcash: when you send a shielded transaction, your wallet generates a cryptographic proof that (a) the sending address controls sufficient balance, (b) the sum of inputs equals the sum of outputs (no value was created), and (c) the transaction is correctly signed. The proof itself reveals nothing about the addresses involved, the balance held, or the amount transferred. The network verifies the proof in milliseconds and accepts or rejects the transaction without ever seeing the underlying data.
Two protocol upgrades changed Zcash significantly. NU5 (2022) introduced the Orchard pool with Halo 2 proofs, removing the original trusted-setup requirement. NU6 (2024) expanded protocol flexibility and refined fee mechanics under ZIP-317. The current Zcash shielded pool is cryptographically clean — no trusted setup, no toxic waste, no ceremony — and remains the gold standard for zero-knowledge privacy at production scale.
Transparent vs shielded addresses: when to use each
Zcash supports two distinct address families with different privacy properties:
- ▸Transparent addresses (t-address, starts with "t1..."). Behave exactly like Bitcoin addresses. Sender, recipient, and amount are publicly visible on the chain. No privacy advantage over BTC. Use case: regulated environments, exchange withdrawals, audit-friendly transactions.
- ▸Shielded addresses (z-address, starts with "u1..." for unified or "zs..." for legacy Sapling). Privacy-preserving via zk-SNARKs. Sender, recipient, and amount are encrypted on-chain. Anonymity set is the active shielded pool — currently in the millions of UTXOs.
Modern Zcash wallets generate unified addresses (u1...) by default, which encapsulate both shielded and transparent receiver components. The recipient wallet decides which receiver to use. This is the cleanest user experience and what most current wallets default to.
For Genghis checkout, the deposit address we display is determined by our payment processor. Your sender address is your choice. Pay from a z-address for shielded-side privacy; pay from a t-address if you specifically need transparent-side disclosure. Either works at checkout.
Zcash vs Monero — which fits your privacy needs?
Both are major privacy chains; both work at Genghis. Three real differences shape the choice:
- ▸Default vs optional privacy. Monero applies privacy to every transaction by default. Zcash applies privacy only to shielded-pool transactions; transparent transactions look like Bitcoin. If you want privacy unconditionally, XMR. If you want optional disclosure (audit, regulatory, peer transparency), ZEC.
- ▸Anonymity set. Monero's anonymity set is effectively the entire active chain. Zcash's anonymity set is the shielded pool — large and growing, but smaller than Monero's. For protocol-level guarantees against the broadest adversary, XMR's set is currently larger.
- ▸Cryptographic posture. Monero uses ring signatures, stealth addresses, and RingCT — battle-tested, conservative cryptography. Zcash uses zk-SNARKs (Halo 2) — more cutting-edge, more academic, no trusted setup since NU5. Both are mature; the choice is more about default behaviour than cryptographic strength at this point.
Practical answer: pay with whichever you already hold and whose properties match your privacy posture. Both are accepted at Genghis without distinction.
Which Zcash wallet should you use?
Zcash wallet choice matters for shielded-pool support — not all wallets handle z-addresses correctly. Stick to wallets with first-class shielded support:
- ▸Zashi. The official mobile wallet from the Electric Coin Co. Shielded by default, clean UX, recommended for most users on iOS or Android.
- ▸Ywallet. Feature-rich mobile and desktop wallet with strong shielded-pool support and multi-pool management. Power-user friendly.
- ▸Nighthawk Wallet. Community-developed mobile wallet with shielded support and good defaults. Open source.
- ▸Zecwallet, Zcashd. Desktop and full-node wallets. Zecwallet is a lightweight desktop client; Zcashd runs the full node, supports both transparent and shielded operations natively, suitable for technical users and larger balances.
- ▸Edge Wallet, Trust Wallet, Exodus. Multi-chain wallets. Most support transparent ZEC (t-address) only; shielded support varies. Convenient if you hold multiple assets but suboptimal if you specifically want shielded transactions.
- ▸Hardware: Ledger. Supports Zcash transparent addresses (t1) via the Zcash app on Ledger Live. Shielded Ledger support has been a long-standing gap. For shielded transactions, software wallets remain the standard.
Related: pay with Monero, Dash, or Bitcoin
If you're choosing among privacy-oriented or established networks, these are the closest paths:
- ▸Monero (XMR). Default privacy, ring signatures + stealth + RingCT.
- ▸Dash (DASH). InstantSend speed, optional PrivateSend mixing.
- ▸Bitcoin (BTC). Original cryptocurrency, widest acceptance.
