Payment notes
Proxy-Seller's FAQ is the source: "What payment options are available on your site? Our site accepts all major payment methods, including PayPal, Visa, Mastercard, Bitcoin, USDT, USDC, BUSD, BNB, TRX, TON and more." The next answer explains that "payments in our service are processed via an external system, so we do not receive the exact reason for a decline", which tells you a gateway sits behind the checkout without telling you which. The presence of TON and TRX alongside USDT is a hint that Tron and TON are among the networks on offer, and of BUSD that the list was written a while ago; neither is a statement we can record as a network. Treat the invoice as the only source for the chain, and with USDT in particular check it twice. The affiliate FAQ on the same page pays out in Bitcoin and "any other cryptocurrency", which is consistent with a crypto-comfortable operator but is not customer-facing acceptance.
Refunds
A return policy page exists but could not be read (it requires JavaScript). Nothing crypto-specific was found. Confirm the terms with support before paying a large balance.
Stablecoin refunds are outbound payments a merchant chooses to send, not automatic reversals. There is no chargeback.
Proxy-Seller names its stablecoins in one FAQ answer and stops there, which puts it in the middle of this category: better than the providers that say “crypto” and worse than Decodo, which publishes a network table.
What the FAQ says
Bitcoin, USDT, USDC, BUSD, BNB, TRX, TON “and more”, processed through an external system the merchant does not name and whose decline reasons it does not see. The list has clues in it — TRX and TON suggest Tron and TON networks are offered; BUSD suggests the list predates 2023 — but clues are not statements, and the record carries no network.
What to do at checkout
Read the invoice for the chain. USDT lives on Tron, Ethereum, Solana, Polygon, TON and more, and a proxy top-up sent on the wrong one to a gateway’s address is a support ticket at best. If USDC is offered on a layer 2, use it; the fee on Ethereum mainnet can rival a small plan.

IPRoyal names USDT, USDC and DAI, also without networks; Decodo names seven networks for USDC. The developer tools category has the rest.
Verification
Verified Verified September 2026
An editor confirmed these payment options against the sources listed below.
The merchant's own FAQ names USDT and USDC explicitly among accepted payment methods. That is merchant documentation naming the coins, sufficient for a verified status without a live purchase, which we did not make. No network and no processor are named, so both fields are empty; BUSD is excluded for the reason in the restrictions. The operating company and address are from the public offer and contacts pages. The return policy page could not be rendered and is recorded as unread rather than summarised.

Added to directory
Added after reading the merchant's own FAQ naming USDT and USDC. Network and processor unpublished.
Limitations
- No network is named for USDT or USDC; the external payment system the FAQ mentions will show it. Read it before sending.
- The FAQ also lists BUSD, which Paxos stopped issuing in 2023; it is not recorded here and its presence suggests the list has not been trimmed.
- Payments run through an unnamed "external system"; Proxy-Seller says it does not receive the reason for a declined payment.
- Returns are governed by a separate return policy page that requires JavaScript to read; confirm terms before a large top-up.
