How to Buy Gift Cards with Ethereum

Last updated: May 7, 2026

Genghis is a London-based Web3 commerce platform offering 4,000+ digital products across 80+ countries, accepting 300+ cryptocurrencies with no KYC and instant on-chain delivery. This guide walks Ethereum holders through the exact process of converting ETH into gift cards, game keys, eSIM data plans, and prepaid cards on Genghis — including network details, gas fee dynamics, and the brands users buy most frequently with Ethereum.

Why use Ethereum to buy gift cards on Genghis?

Ethereum is the second-largest cryptocurrency by market capitalization and the base layer for most of the Web3 ecosystem — DeFi, NFTs, stablecoins, and the majority of token launches all settle on Ethereum or one of its L2 networks. Most ETH holders use the asset for gas, staking, or as a long-term store of value. A growing share also use it for everyday spending.

Genghis removes the cash-out friction. Holders go directly from Ethereum to a redeemable digital code, with no bank account in the loop and no fiat off-ramp paperwork. The Ethereum gift cards page lists every brand available for purchase with ETH, and the broader crypto-buying hub covers all 300+ supported tokens.

The platform is accelerated by the Algorand Foundation and Techstars × Cardano Founder Catalyst, operated by Genghis Ltd (Company No. 16315448). There is no platform fee beyond the Ethereum gas fee that your wallet attaches to the transaction — the price displayed at checkout is the price you pay.

How Genghis processes Ethereum payments

When Ethereum is selected at checkout, Genghis generates a one-time receiving address bound to the specific order. The address is unique to that order — it is not reused, and Genghis does not maintain shared deposit addresses for ETH payments. This keeps on-chain order matching automatic and eliminates manual reconciliation.

The amount displayed at checkout is locked at the rate quoted at order time, with a short window during which the rate is honored. Send the exact ETH amount shown — overpayment is credited, underpayment may delay confirmation. The full checkout flow is documented in the Foundation tier.

Three points are worth flagging for first-time Ethereum buyers. First, copy the receiving address by clicking or scanning the QR code rather than typing it manually — Ethereum addresses are checksummed but a single character error is still a real risk if you type by hand. Second, send the exact amount shown to the wei if your wallet allows it. Third, the gas fee your wallet attaches is separate from the order amount — make sure your wallet has enough ETH to cover both the order amount and the gas fee before broadcasting.

Ethereum mainnet, gas dynamics, and confirmation

Genghis accepts ETH on Ethereum mainnet — the canonical Layer 1 chain. Layer 2 networks like Arbitrum, Optimism, Base, and zkSync are not currently supported as ETH payment rails at Genghis checkout. If your ETH lives on a Layer 2, you will need to bridge it back to mainnet before paying, which adds time and a bridge fee. Many users find it more practical to either keep some ETH on mainnet for spending or pay with a different supported asset that matches the network they are on.

Ethereum's fee model is dynamic. Since the EIP-1559 upgrade, every transaction includes a base fee (which is burned) and an optional priority tip (which goes to the validator). The base fee adjusts block by block based on demand — when blocks are full, the base fee rises; when blocks are partly empty, it falls. Wallets typically suggest a gas price targeting the next one or two blocks; using that suggestion keeps confirmation predictable.

Confirmation times are fast in normal conditions: blocks are produced about every 12 seconds, and most Genghis orders are confirmed within one to three minutes after broadcast. During congestion — major NFT mints, token launches, large-scale on-chain events — gas can spike sharply and a transaction submitted at a previously sufficient gas price may sit in the mempool until conditions calm down. Modern wallets surface a "speed up" button that re-broadcasts the same transaction with a higher gas price; using it gets stuck payments confirmed quickly, and Genghis automatically picks up the higher-fee replacement.

Exchange withdrawals add their own latency. Some exchanges batch ETH withdrawals on a fixed schedule, which adds time before the transaction even hits the mempool. The transaction has to leave the exchange first; Genghis cannot accelerate that step.

Holding ERC-20 stablecoins? Use the right token

Many Ethereum users also hold ERC-20 stablecoins — primarily USDT and USDC — in the same wallet. Stablecoins are often the better payment choice for gift card purchases because the price is fixed in dollars and the user does not need to mentally convert from ETH market price to USD value at checkout. If you are holding stablecoins specifically for purchases, see the dedicated guides for buying gift cards with USDT — including the cheaper TRC20 and Polygon network options for USDT — alongside the ETH option here.

That said, paying in ETH directly remains attractive for users with a long ETH position who want to spend it down without an off-ramp. The choice is between the convenience of a stable-priced asset and the simplicity of paying with what you already have at hand.

Top brands Ethereum holders buy at Genghis

Looking at the most frequently purchased gift cards in the Ethereum payment cohort, three categories dominate: ecommerce, digital subscriptions, and gaming. The most popular individual products are Amazon Japan gift cards, Apple App Store & iTunes gift cards, and Spotify gift cards. Together they cover most digital-purchase use cases: physical and digital goods on Amazon, any iOS app or media purchase via Apple, and music subscriptions globally via Spotify.

The brand mix tends to skew slightly more toward subscription services compared to the Bitcoin cohort, which is consistent with Ethereum's user base — Ethereum holders are on average more active spenders rather than long-term hodlers, and recurring digital subscriptions match that profile. Beyond the top three, ETH users also frequently purchase Steam, Netflix, PlayStation Network, and Uber gift cards. The popular products list updates continuously based on real-time order volume, and the same five-step checkout flow applies regardless of which brand is chosen.

How to buy gift cards with Ethereum on Genghis

The full purchase flow is five steps and typically takes two to four minutes from cart to redeemable code, with most of that time spent waiting for on-chain confirmation.

1. Browse the Genghis catalog and select the gift card brand and denomination you want to buy.
   
2. Click checkout, enter your email address, and choose Ethereum as your payment method.
   
3. Send the exact Ethereum amount shown to the one-time payment address generated for your order.
   
4. Wait for on-chain confirmation. Ethereum payments typically confirm within one to three minutes depending on network congestion.
5. Receive your gift card code by email and on the order success screen, ready to redeem instantly.
   

Privacy, KYC, and Ethereum at Genghis

Genghis does not require identity verification for digital goods checkout. There is no account creation step, no document upload, and no liveness check. The only personal data collected is the email address used for code delivery.

Ethereum, like Bitcoin, is pseudonymous: every transaction is permanently visible on the public ledger, and addresses can be linked through chain analysis if a buyer is not careful about wallet hygiene. Most Ethereum users transact from wallets already linked to dApps, exchanges, or NFT activity, which makes the Ethereum address more identifiable on-chain than a fresh Bitcoin address. Buyers who want stronger payment-leg privacy can use a separate wallet for purchases or pay with a different asset designed for privacy at the protocol level. The full security and privacy framework is documented in the Foundation tier.

Common Ethereum use cases on Genghis

Three patterns repeat across the Ethereum payment cohort. The first is the active DeFi user converting profits or yield into spendable value without going through a centralized exchange — paying directly with ETH skips the on-ramp, off-ramp, and KYC review. The second is the NFT seller spending floor-price proceeds on subscriptions and digital purchases. The third is the international remote worker paid in ETH or stablecoins on Ethereum who needs to convert earnings into local-purchase power via gift cards.

A fourth pattern is the cross-chain refugee: users who hold ETH on Layer 2 networks for gas savings and need to bridge back to mainnet for spending. For these users, the practical advice is to keep a small mainnet ETH balance specifically for Genghis purchases, or to pay with a stablecoin that natively supports cheaper networks such as USDT on Tron or Polygon.

Genghis supports 300+ cryptocurrencies at the same checkout, so users with mixed crypto portfolios can pay with whichever asset has the lowest opportunity cost at the moment of purchase. For more on the philosophy behind crypto-native commerce, see What is Genghis. The Ethereum Foundation's wallet selection guide is also a useful primer for users new to self-custody, particularly the sections covering hardware wallets and seed phrase management which are the two areas where most Ethereum users get tripped up early on.

Frequently Asked Questions

Why use Ethereum to buy gift cards on Genghis?

Ethereum is the second-largest cryptocurrency by market capitalization and the base layer for most of the Web3 ecosystem. Genghis lets ETH holders convert their balance directly into 4,000+ digital products with no KYC at checkout. Confirmation is fast — usually one to three minutes — and the gift card code is delivered the moment the transaction is mined.

Which gift cards can I buy with Ethereum?

Ethereum can be used to buy any gift card listed in the Genghis catalog, including Amazon, Steam, Apple App Store, Spotify, Netflix, PlayStation, Xbox, Uber, and hundreds of other brands. The same applies to game keys, eSIM data plans, and prepaid cards. The catalog covers 80+ countries and shows real-time availability.

Do I need an Ethereum wallet to buy gift cards on Genghis?

Yes. You need an Ethereum-compatible wallet that can send ETH to an external address. MetaMask, Rabby, Trust Wallet, Rainbow, and hardware wallets like Ledger and Trezor all work. A withdrawal directly from a centralized exchange also works. Genghis does not host your ETH and does not require account creation; you only need to send the exact amount shown at checkout.

Which Ethereum networks does Genghis support?

Genghis accepts ETH on Ethereum mainnet. Layer 2 networks such as Arbitrum, Optimism, and Base are not currently supported for native ETH payments at Genghis checkout. If you hold ETH on a Layer 2, you will need to bridge it back to mainnet before paying, or pay with a different supported asset.

How fast does the Ethereum payment confirm on-chain?

Ethereum produces a new block roughly every 12 seconds. Most Genghis orders confirm within one to three minutes from the moment your wallet broadcasts the transaction. If the gas price you set is below the current network floor, the transaction will sit in the mempool until conditions improve. Once confirmed, the gift card code is released immediately. See Genghis Delivery Times for the full breakdown.

Are there any fees beyond the Ethereum gas fee?

Genghis does not charge a separate platform fee on top of the displayed product price. The only cost beyond the gift card itself is the Ethereum gas fee, which is paid to validators and set by your wallet, not by Genghis. Gas fees vary with network demand — checking a gas tracker before broadcasting helps avoid overpaying during congestion.

What if my Ethereum payment is delayed or does not confirm?

If your transaction is stuck in the mempool, the most common cause is a gas price that fell below the current floor. Most modern wallets let you speed up the transaction by re-broadcasting it with a higher fee. If the order remains pending after that, Code Not Working — Troubleshooting (article coming soon) or contact Genghis support with your transaction hash and we will reconcile the order.
