On paper this is the most boring swap we offer: a dollar for a dollar. In practice it is an issuer trade. USDT is run by Tether, USDC by Circle, and the two companies have different reserves, different regulators, different histories, and different habits. When you swap between them, the number in your wallet barely moves. Whose promise backs that number changes completely.
People come to this corridor for concrete reasons. A platform pays out only in USDC. A DeFi protocol's deepest pool wants USDC. A US-facing business will settle invoices in Circle's coin and nothing else. Or someone simply read enough about reserve attestations to decide they want the issuer that publishes them monthly. None of these require an opinion on the eternal Tether debate. They just require the other dollar.
Let us do the honest math before you scroll further. You will pay our flat 2% spread plus the Ethereum payout fee to move between two assets worth about a dollar each. On a 20 USDT swap that cost is plainly visible and plainly silly. On a meaningful balance, or when a platform flat-out requires USDC, it is the fair price of getting the right dollar without opening an exchange account. The quote shows the exact USDC number before you commit and locks it the moment you create the swap, so the decision stays yours.
Mechanics are quick: the Tron deposit confirms in about a minute, and the USDC payout lands on Ethereum a few minutes later. Most orders finish in 5 to 15 minutes, with no account, no email, and an order page for a receipt.
Confirmation counts and minimums above are the live values our exchange engine uses, not marketing copy. Block times are network averages and can vary.
Choose how much USDT you are sending. The card quotes your USDC payout with the spread and network fee already counted in. Paste the Ethereum (ERC-20) address the payout should land at, plus an optional USDT refund address in case the swap cannot complete.
You get a deposit address on the Tron (TRC-20) network. Send your USDT to it from any wallet, in one payment of at least 10 USDT. No account, no email, nothing to install.
Your deposit needs 20 confirmations on Tron (TRC-20), about 1 minute. We screen it before the exchange starts, then send USDC to your address and post the transaction hash on your order page.
Issuer diversification, the boring kind of smart. Keeping all your stablecoin savings in one company's IOU is a single point of failure, and both of these coins have wobbled. USDC fell hard for one weekend in March 2023 when a bank holding part of its reserves collapsed. USDT has traded under the peg in stressed markets and spent years fielding questions about its books. Both recovered every time. Neither is guaranteed to next time. Splitting the pile across issuers is the kind of risk management that costs little and asks nothing of your forecasting skills.
Requirements, not preferences. Payroll services that settle in USDC. Lending markets where the USDC side is twice as deep. OTC desks, US-registered platforms, accounting departments that want the coin with monthly attestations from a major audit firm. When the counterparty names the coin, the debate is over, and the only question left is how to convert without a three-day exchange onboarding.
The rail change is part of the trade. Your Tether arrives here on Tron, where fees are pennies and most P2P flow lives. Your USD Coin leaves on Ethereum, where the bulk of DeFi liquidity and ERC-20 infrastructure sits. So the swap moves your dollars from the cheap payments rail to the deep liquidity rail in the same motion. For plenty of users that, not the issuer question, is the actual point.
What this swap does not change: both coins are centralized, both issuers can freeze addresses at law enforcement's request, and both ledgers are public. Swapping USDT for USDC swaps one counterparty for another. It does not buy privacy and it does not buy immunity. If nobody-can-freeze-it money is what you want, that is Monero's department, and we run those corridors too.
We launched CoinVast in 2026 for exactly these one-payment conversions. Deposits are screened before the exchange starts, so your Tether either proceeds at the quoted terms or returns to your refund address. No mid-swap freezes, no documents demanded halfway through, and a completed swap is final.
Three small things sit between the two dollars. USDT and USDC each trade within a whisker of $1.00 but rarely at it, so there is a tiny market rate between them. Our flat 2% spread sits on top of that. And the Ethereum network fee for the payout comes out as well. The card adds all of it up and shows the final USDC amount before you send, locked the moment you create the swap, so there is no arithmetic homework and no surprise on the order page.
About 5 to 15 minutes for most orders. The Tron deposit needs 20 confirmations at roughly 3-second blocks, which is about one minute. The exchange itself takes seconds, and the ERC-20 payout typically confirms on Ethereum within a couple of minutes of being sent. Stablecoin in, stablecoin out, with barely enough waiting to make tea.
Yes. Circle can blacklist addresses, exactly as Tether can, and both have done it when law enforcement asked. That is the nature of centralized stablecoins, not a quirk of either company. Our screening runs before the exchange starts, so the swap itself will not be frozen midway. What the coins do after they reach your wallet follows the issuer's rules, whichever issuer you picked.
It is differently risky, which is not the same as safer. Circle publishes monthly reserve attestations and operates squarely inside US regulation. Tether has the longest track record, the deepest liquidity in most of the world, and a history of answering reserve questions later than people would like. Note that the regulated one is also the one that depegged hardest in recent memory, during the March 2023 bank failure. We sell the swap, not a verdict. Decide whose story you trust and size your holdings accordingly.
Yes. The card lets you switch the payout network, and Base fees run far below Ethereum mainnet fees. Both networks use the same 0x address format, and most self-custody wallets can hold USDC on either. The thing to check is the receiving side: if the payout goes to a service or an exchange, confirm it actually supports USDC on Base before choosing it, because tokens credited on a network a platform ignores are a headache you do not need.
The minimum is 10 USDT, and honestly, at that size the spread plus the Ethereum fee takes a visible bite out of a dollar-for-dollar trade. The quote makes the cost obvious before you commit, which is the point of printing it. Small test swaps to check us out make sense. Small swaps as a habit, on this particular pair, mostly pay for gas. There is no upper limit on the card, though very large deposits can get a human look before the exchange starts.
No. No registration, no email, no KYC under the screening threshold. You paste an Ethereum address, send one TRC-20 payment, and bookmark the order page, which carries the amounts, the rate, and both transaction hashes. Screening happens before the exchange begins: pass and it proceeds, fail and your Tether returns to your refund address minus the network fee.
Setting it up takes under a minute. The blockchain handles the rest.
