Paying with USDT: TRC-20 or ERC-20

Tether is the obvious asset for buying hardware: the quote and the coin are the same unit, so a thirty-minute rate lock is a formality rather than a gamble. The one thing that goes wrong is the network, and it goes wrong permanently.

The same token, two chains, two addresses

USDT exists on both TRON and Ethereum, and the checkout treats them as two separate payment options because they are. The address formats differ — a TRON address starts with a T, an Ethereum address with 0x — and sending TRC-20 tokens to an ERC-20 address, or the reverse, does not bounce. It lands somewhere unrecoverable.

So pick the network in the checkout first, then copy the address it gives you, then send from a wallet on that same network. If your exchange offers a withdrawal network dropdown, that dropdown has to match. This is the single most common way a crypto payment is lost, and it has nothing to do with the shop.

Which one to use

TRC-20 for almost every order. Fees are a fraction of a dollar, confirmation takes seconds, and the cost does not move with congestion. On a $300 component the Ethereum route can quietly add several dollars to what you pay, all of it to validators rather than to us.

ERC-20 is worth it when your funds already sit on Ethereum and moving them to TRON would cost more than the fee difference, or when you are paying from a contract wallet that only exists there. For a straightforward purchase out of an exchange balance, TRON is the cheaper answer.

Why a stablecoin makes the quote boring

Prices here are set in US dollars. Pay in Bitcoin and the thirty-minute lock is doing real work, because the dollar value of what you are sending moves while you decide. Pay in USDT and the two units are the same thing: the amount quoted is the amount owed, and the lock is there for consistency rather than protection.

That also makes refunds simple. A refund is issued in the asset that was paid, at the rate of the day it is issued — for a stablecoin, that is the amount you sent.

How paying works here

  1. Fill the basket

    No account, no registration. Prices are in US dollars; the header switches the display currency and the settlement asset independently.

  2. Give an address

    A delivery address and a contact e-mail, and nothing else. An e-mail alias is accepted. We ship insured to 56 countries.

  3. Pick the asset and pay

    The checkout quotes the exact amount in your chosen asset and holds it for 30 minutes. Send to the address shown — it is generated here, not at a payment processor.

  4. It ships

    The parcel leaves once the payment confirms, in plain outer packaging. Twenty-four-month warranty, thirty-day returns on unopened items, refunded in the asset you paid with.

Nothing is added for paying in crypto, and no payment processor sits in the middle. The only cost outside the price is the network fee your own wallet pays to broadcast.

Questions

What happens if I send USDT on the wrong network?
The funds go to an address on a chain where your transaction does not correspond to the address we control. We cannot recover them, and neither can the network. Check the dropdown before sending; it is the whole risk of this payment method.
Is USDT cheaper to send than Bitcoin?
On TRON, by a wide margin and consistently. On Ethereum it depends entirely on gas at that moment, which is exactly the unpredictability TRON avoids.
Do you accept USDC or other stablecoins?
The accepted list is shown in the checkout and on the coins page. It is the authoritative list — it is read from the same configuration the payment engine uses, so it cannot drift out of date.
Does paying in a stablecoin cost more than paying in Bitcoin?
No. There is no surcharge for any asset. The only difference between assets is the network fee your own wallet pays to broadcast.
Can I still pay late?
Yes. A payment that arrives after the quote expires is detected and reconciled against the order rather than lost. With a stablecoin the amount does not need requoting anyway.
