USDT or USDC: which one to actually send

Same dollar, different plumbing. The difference shows up in fees, exchange support and what happens if something goes wrong.

Both are dollar stablecoins, and on face value they are the same money. For a payment of a few hundred dollars the difference looks small, but it is not zero, and it decides three things: what the fee costs, whether your funds can leave the exchange cleanly, and how painful a mistake becomes. So the order of choosing matters — read the invoice first, then where your money sits, then which coin.

Fees

On TRON, USDT transfers are cheap and universally supported, which is why it is the default. USDC exists there too, but with far less liquidity and fewer wallet defaults. On Ethereum both get expensive when the network is busy, sometimes by several times on the same minute; on BSC, Polygon and Solana both are effectively negligible.

Practical rule: send what the invoice asks for. Which chain is cheapest for your coin and which chain the gateway is actually watching are unrelated questions. Picking the cheap one anyway converts a few cents of saved fee into a manual reconciliation.

Exchange and wallet support

USDT has broader support, especially on TRON: almost every wallet, exchange and payment gateway handles it. USDC is well supported on Ethereum, Solana and Base, less so on TRON.

The trap shows up at withdrawal time, because an exchange lists coin and chain as one combined option: TRC20-USDT and ERC20-USDT are two different entries, and picking the wrong one is a wrong-chain send. The network step on the withdrawal screen deserves more attention than the coin step.

If your funds sit on an exchange that only withdraws one of the two to your network of choice, the decision is made for you — and switching networks is usually less trouble than moving exchanges.

What happens when something breaks

Recovery depends on the issuer and the chain, not on the symbol. A wrong-network send is hard for both: it needs manual work, is handled case by case outside the standard refund policy, and no one can promise an outcome in advance. A right-address, wrong-amount transfer is easy for both: top up the shortfall, or have the surplus returned against unused days. A transfer to an address that was never ours is simply not ours to return.

Two habits therefore matter far more than the coin you pick. Copy the address from the invoice every time — never retype it, never reuse an old order's address. And keep the transaction hash: it shows amount, address, time and confirmations in public, and it is the only way support can locate a disputed transfer. No email is sent here, so the hash plus the order number are your whole record.

Our side

USDT and USDC, plus native TRX, SOL and TON, across the eight networks the cashier lists: TRON, Ethereum, BSC, Polygon, Solana, TON, Aptos and Plasma. There is no card field, no PayPal and no bank transfer.

One invoice means one network and one exact amount. Do not split an order across two transfers, and do not merge two orders into one: an aggregated payment clears neither order and becomes one movement nobody can claim. The network fee sits on top and is carried by the sender; it travels with the refund only when the failure was ours.

The cashier shows the precise address and amount for the pair you choose. Refunds go back on-chain to the address you sent from, in the same asset, usually confirmed inside twelve hours.

If a payment does not appear, the USDT guide lists the three things to check before contacting anyone; if the amount and network were right and it still sits unmatched, read payment not matched; and the status page shows what a live order looks like.

Common questions

Which should I keep in my wallet for these payments?

Whichever your exchange can already withdraw to the network the invoice names. The coin is the smaller decision; the chain is the one that breaks payments.

Do you accept both?

Yes — USDT and USDC, plus native TRX, SOL and TON, across eight networks shown at checkout. No card, no PayPal, no bank transfer.

Can I send half in USDT and half in USDC?

No. One invoice carries one network and one exact amount in one asset. Mixed or split transfers do not clear the order; they become unmatched movements.

I sent USDC on the wrong chain. Is it recoverable?

It is worked by hand, case by case, outside the standard refund policy, with no outcome promised. Send the transaction hash and the order number to @cdkstorebot immediately.

Who pays the network fee?

The sender, on top of the invoice amount. Do not let the wallet subtract it from the transfer, or the arrival will be short and the match will fail.
