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 USDC holders through the exact process of converting Circle's stablecoin into gift cards, game keys, eSIM data plans, and prepaid cards on Genghis — including network selection across Ethereum, Solana, Polygon, Algorand, and Base, plus the brands users buy most frequently with USDC.

Why use USDC to buy gift cards on Genghis?
USDC is the second-largest stablecoin by market capitalization and the most widely adopted dollar-backed token in regulated and institutional contexts. It is issued by Circle, a US-based financial technology company, and is backed one-to-one by US dollar reserves held in regulated financial institutions. Circle publishes monthly attestations of those reserves, audited by an independent accounting firm — a level of transparency that distinguishes USDC from most other stablecoins on the market.
For end users, the practical effect is the same as any dollar-pegged asset: the price you see at Genghis checkout matches your USDC balance one-to-one, with no exchange-rate risk between order and confirmation. Combined with Genghis's no-KYC digital goods checkout and instant code delivery, USDC is among the most predictable ways to spend crypto. The USDC gift cards page lists every brand available, 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 network fee that your wallet attaches to the USDC transaction.
How Genghis processes USDC payments
When USDC is selected at checkout, Genghis prompts you to choose a network. This choice matters: USDC is issued by Circle as a native token on each supported chain, but the issuance contracts are independent — sending USDC on Ethereum to a Solana address is not interchangeable, and the funds will not arrive at the order destination.
Once the network is chosen, Genghis generates a one-time receiving address bound to that order on that specific network. The address is unique to your order — it is not reused, and Genghis does not maintain shared deposit addresses for stablecoin payments. The amount displayed at checkout is locked at the rate quoted at order time. Send the exact USDC amount shown — overpayment is credited, underpayment may delay confirmation. The full checkout flow is documented in the Foundation tier.
USDC networks Genghis supports
USDC is one of the most multi-chain stablecoins in circulation. Genghis supports USDC payments on the networks where Circle has issued the token natively, with each network offering a distinct trade-off across fees, confirmation time, and wallet compatibility.
USDC on Ethereum (ERC20) is the original USDC issuance and remains the most widely supported by wallets, exchanges, and hardware devices. Network fees scale with Ethereum gas prices, which can be meaningful during congestion. ERC20 is appropriate when you already hold USDC on Ethereum, when you are paying a large amount and the fixed gas fee is a small percentage of the total, or when you are using a hardware wallet that only supports Ethereum.
USDC on Solana offers near-instant confirmation and negligible fees. Solana is the most active network for USDC volume by transaction count — much of the day-to-day USDC spending and transfer activity now happens on Solana. Wallets like Phantom and Solflare handle USDC natively. For users already operating in the Solana ecosystem, this is the default choice.
USDC on Polygon sits between Ethereum and Solana on the fee curve — fees are very low, confirmation is sub-minute, and most EVM-compatible wallets including MetaMask handle Polygon after a one-time network add. Polygon is a strong choice for users who already operate in the Ethereum ecosystem but want lower fees.
USDC on Algorand offers instant finality (block time around three seconds with single-block finality), fees in fractions of a cent, and a carbon-negative settlement layer. Algorand was an early home for native USDC — Circle issued the token directly on the network rather than through a bridge. Wallets like Pera and Defly handle USDC on Algorand natively.
USDC on Base is the newest of the supported networks. Base is an Ethereum Layer 2 built by Coinbase, with low fees and fast confirmation, and Coinbase has positioned USDC as the default stablecoin on Base. EVM wallets like MetaMask handle Base after adding the network.
Confirmation times and what to expect
Across the supported networks, confirmation times vary by an order of magnitude:
- Solana / Algorand: seconds. Almost real-time finality.
- Polygon / Base: under a minute. Sub-block-time confirmation in most conditions.
- Ethereum (ERC20): one to three minutes typical, longer during gas spikes.
Once confirmation is recorded on-chain, Genghis releases the gift card code instantly to your email and the order success screen. There is no manual review step — on-chain confirmation is the trigger for code delivery.
Top brands USDC holders buy at Genghis
USDC users at Genghis buy across the catalog, but three brands dominate by order volume in the USDC payment cohort: Amazon Japan gift cards, Netflix gift cards, and Apple App Store & iTunes gift cards. The mix reflects the underlying user base — USDC holders skew slightly more toward developed-market users with subscription-heavy spending profiles, particularly in North America and Europe.
The dollar-pegged nature of USDC also makes it the preferred token for higher-value gift card purchases — a $500 Amazon gift card paid in USDC carries no exchange-rate risk, while the same purchase paid in a volatile asset could end up costing measurably more or less depending on price movement during confirmation.
Beyond the top three, USDC users also frequently buy Steam, Spotify, PlayStation Network, and Uber gift cards. The order pattern is closer to the USDT cohort than to native crypto cohorts like BTC or ETH — stablecoin holders tend to use the asset for everyday purchases at predictable price points rather than speculative or one-off conversions.
How to buy gift cards with USDC on Genghis
The full purchase flow is five steps. Confirmation time varies meaningfully across networks — most orders complete within seconds to a few minutes from cart to redeemable code.
- Browse the Genghis catalog and select the gift card brand and denomination you want to buy.
- Click checkout, enter your email address, choose USDC, and select your preferred network — Ethereum, Solana, Polygon, Algorand, or another supported chain.
- Send the exact USDC amount shown to the one-time payment address generated for your order on the network you selected.
- Wait for on-chain confirmation. USDC confirms within seconds on Solana and Algorand, under a minute on Polygon, and one to three minutes on Ethereum.
- Receive your gift card code by email and on the order success screen, ready to redeem instantly.
USDC vs USDT — which stablecoin should you use?
Many crypto users hold both USDC and USDT and treat them as roughly interchangeable for everyday spending. They serve the same fundamental purpose: dollar-stable settlement on-chain. The differences are at the issuer and reserves level.
USDC is issued by Circle, a US-based regulated financial technology company, with monthly attestations of fully reserved dollar backing held in segregated accounts at audited US banks. USDT is issued by Tether Limited, with broader reserve composition that includes treasuries, secured loans, and other assets. For users who prioritize transparency and US regulatory alignment, USDC is the more conservative choice. For users who prioritize maximum network coverage and exchange liquidity, USDT often has a slight edge.
For payment purposes at Genghis, both work identically. If you already hold one, use what you have. If you are choosing fresh, USDC on Solana or Algorand offers the cleanest combination of stable pricing, fast finality, and very low fees. See the full USDT guide for the sibling-stablecoin breakdown.
Common USDC use cases on Genghis
Three patterns repeat across the USDC payment cohort. The first is the institutionally cautious buyer who wants the stability of a dollar peg with the strongest available transparency posture — USDC's monthly attestations and US-banking-rail reserve structure make it the preferred stablecoin for users who prioritize compliance clarity. The second is the active Solana user spending USDC kept in a Solana wallet for daily transactions; the network's near-instant finality and negligible fees make it functionally indistinguishable from a fiat payment from the user's perspective. The third is the cross-border worker paid in USDC who converts directly to local-region gift cards without going through a banking intermediary.
For all three patterns, the same five-step checkout flow applies, with the network choice optimized for the wallet the user already has. Genghis does not push users toward any specific network — the optimal choice depends on where USDC currently lives in the user's wallet stack.
Privacy, KYC, and stablecoins at Genghis
Genghis does not require identity verification for digital goods checkout, regardless of which token or network you pay with. 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.
USDC, like other public-blockchain assets, is pseudonymous: each transaction is permanently visible on the public ledger, and Circle retains the technical capability to freeze addresses linked to sanctioned activity. This is a property of the asset itself, not of Genghis. The full security and privacy framework is documented in the Foundation tier.

Genghis supports 300+ cryptocurrencies at the same checkout. For more on the platform itself, see What is Genghis and How Genghis works. Circle's official USDC resource at circle.com/usdc covers issuance details, reserve attestations, and the latest list of supported networks.
Frequently Asked Questions
Why use USDC to buy gift cards on Genghis?
USDC is a fully reserved, US-dollar-backed stablecoin issued by Circle, audited monthly. The dollar peg means the price you see at Genghis checkout matches your USDC balance one-to-one, with no exchange-rate risk during confirmation. Combined with Genghis's no-KYC checkout and instant code delivery, USDC is one of the most predictable and transparent ways to spend crypto.
Which gift cards can I buy with USDC?
USDC 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 a USDC wallet to buy gift cards on Genghis?
Yes, and the wallet must support the specific network you choose at checkout. USDC on Ethereum needs an EVM wallet like MetaMask or a hardware wallet; USDC on Solana needs a Solana wallet like Phantom; USDC on Algorand needs Pera or Defly. Multi-chain wallets such as Trust Wallet handle several USDC networks. Confirm wallet compatibility before sending.
Which USDC networks does Genghis support?
Genghis supports USDC across multiple networks where Circle has issued the token natively, including Ethereum, Solana, Polygon, Algorand, and Base. Network fees, confirmation times, and wallet compatibility differ. Solana and Algorand offer the fastest finality and lowest fees; Ethereum has the deepest wallet support but the highest gas costs during congestion.
How fast does the USDC payment confirm on-chain?
Confirmation depends on the network. USDC on Solana or Algorand confirms in seconds. USDC on Polygon confirms in well under a minute. USDC on Ethereum mainnet confirms in one to three minutes, longer during gas spikes. See Genghis Delivery Times for the full breakdown.
Are there any fees beyond the USDC network 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 network fee for the chain you selected, which is set by the network and your wallet, not by Genghis. Solana and Algorand fees are fractions of a cent; Ethereum fees scale with gas prices.
What if my USDC payment is delayed or does not confirm?
If a USDC payment is delayed, the most common cause is sending on a different network than the one selected at checkout — for example, sending Solana USDC to an Ethereum address. Always match the network. If the network is correct and the transaction is broadcast but unconfirmed, Code Not Working — Troubleshooting (article coming soon) or contact Genghis support with your transaction hash.
