A dash means we found no evidence of support, not that support is impossible. Coin availability at checkout can differ by country and product.
Payment networks
Which network each coin is accepted on, exactly as G2G documents it. A coin and a network appearing in the same record does not by itself mean the two go together.
Each pairing above is taken from G2G’s own documentation or its named gateway’s. Absence means we found no evidence, not that a chain will fail.
Pay on the cheapest network offered — G2G receives the same amount either way, so the fee comes out of your side. Our network comparison covers which to pick.

Payment notes
G2G's payment guide is the kind of document this directory wishes every merchant published. Under "Cryptocurrency" it lists Binance Pay, Bitcoin, Ethereum, "Tether USDT (ETH)", "Tether USDT (Polygon)", "USDC" and "USDC (Polygon)", each marked "Instant" with a 0.99% fee. The per-method guides describe the flow: select the method at checkout — the USDC page is titled "Checkout with USDC (ERC20)" — send payment to the address provided or scan the QR code, and receive the order number. G2G asks you to let the page finish loading after paying to avoid "floating orders". Choose Polygon for anything small: the surcharge is identical but the network fee is not. No processor is named; the checkout appears to be G2G's own.
Refunds
Not documented for crypto payments. G2G runs a marketplace with seller-delivery guarantees and dispute handling through its help centre; refunds, where granted, are a marketplace decision and are not described as returning to a wallet.
Stablecoin refunds are outbound payments a merchant chooses to send, not automatic reversals. There is no chargeback.
G2G publishes its payment methods the way an exchange publishes fees: a table, one row per method, speed and surcharge stated. It makes for a short verification and a useful record.
What the table says
Seven crypto rows, all “Instant”, all 0.99%: Binance Pay, Bitcoin, Ethereum, USDT on Ethereum, USDT on Polygon, USDC on Ethereum, USDC on Polygon. The stablecoin rows name their networks, which is the detail most merchants omit and the reason this record can list networks at all. Nothing else — no Solana, no Base, no Tron.
OffGamers, which Triple-A’s case study groups with G2G, publishes the same shape of table with one difference: there, USDT on Polygon costs 1.99%. Here every crypto method is priced the same.
What you are buying
A marketplace, not a store. Independent sellers list accounts, currency, items, boosting and top-ups across hundreds of games, and delivery comes from the seller. The payment method has no effect on that, and a dispute is a marketplace matter handled through G2G’s help centre rather than a chargeback — there is none on a stablecoin payment in any case.
Which network
Polygon, for anything small. The surcharge is the same on both; the network fee is not, and a $10 top-up paid on Ethereum mainnet at a busy moment loses a visible slice to gas.

OffGamers for top-ups and gift cards with a near-identical fee table; Bitrefill and Coinsbee for game credit on more networks. The gaming category has the rest.
Verification
Verified Verified September 2026
An editor confirmed these payment options against the sources listed below.
G2G's own payment guide, on its own domain, names both stablecoins with their networks and surcharges, and its per-method pages describe the checkout. That is merchant documentation naming coin and network, which carries a verified status without a live checkout, which we did not run. The guide is generated per shopping currency; we read the USD view, and availability may differ by region or currency. G2G's own tagline supplies the company description; it does not publish a head-office location on the pages we read and none is asserted. Triple-A, a licensed gateway, publishes a case study describing G2G and OffGamers together as stablecoin merchants, which is consistent with the guide but is not needed to carry the claim.

Added to directory
Added after reading G2G's own payment guide, which names USDC and USDT on Ethereum and Polygon with a 0.99% fee each.
Limitations
- Ethereum and Polygon only. No Solana, Base, Tron or any other network is listed for either stablecoin.
- Every crypto method carries a 0.99% surcharge, the same as Bitcoin, Ethereum and Binance Pay.
- A peer-to-peer marketplace: what you buy comes from a third-party seller, and the payment method has no bearing on delivery.
- Payment methods offered can differ by the currency you shop in; the guide lets you switch between nineteen.
