Select USDC as the coin you're sending, paste your USDT wallet address (TRC-20 for dirt cheap fees, ERC-20 if you want to stay on Ethereum, or TON if Telegram is basically your operating system), and hit swap. CoinVast grabs you a rate near 1:1 with a flat 2% spread, locked the moment you create the swap, shows a deposit address, and once your USDC confirms on chain, your USDT lands in your wallet. Minimum send is 10 USDC. Nobody asks for your name, your email, or a selfie of you holding yesterday's newspaper.

This might be the most boring swap in all of crypto, and that's exactly why it works. You're not speculating. You're not timing the market. You're taking one dollar and turning it into a slightly different dollar. USDC and USDT are both stablecoins pegged to the US dollar, both backed by reserves, both sitting at roughly $1.00 at all times. The difference is who's behind them, where they're accepted, and which ecosystem treats them as the default unit of account.
USDC is Circle's baby. Regulated in the US, monthly reserve attestations, strong banking relationships, the kind of stablecoin your compliance officer would take home to meet the parents. It's the coin institutions feel comfortable holding because there's a clear legal entity standing behind it, filing reports, playing by the rules, and generally being the responsible adult in the room.
USDT is Tether. The original stablecoin. The one that's been around since 2014 and has survived every crisis, scandal, FUD cycle, and market implosion the crypto world has thrown at it. It's the most traded stablecoin on earth by a mile. More pairs, more liquidity, more exchanges, more volume. If USDC is the regulated bank account, USDT is the cash in your pocket that works everywhere, no questions asked.
In 2026, swapping between them costs almost nothing and takes minutes. The rate hovers around 1:1 with spreads so thin you'd need a microscope to see them. CoinVast handles the swap without accounts, without KYC, and without making you feel like you're applying for a mortgage. You send USDC, you get USDT. Pick your payout network (TRC-20 on Tron is fastest and cheapest, ERC-20 keeps you on Ethereum, TON puts your Tether inside the Telegram world), confirm, and you're done.
The whole point of doing this on CoinVast instead of a centralized exchange is that you skip the account creation, the identity verification, the "please upload a government ID and wait 48 hours" dance. Your wallet sends USDC, your wallet receives USDT. That's the entire relationship.
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 USDC you are sending. The card quotes your USDT payout with the spread and network fee already counted in. Paste the Tron (TRC-20) address the payout should land at, plus an optional USDC refund address in case the swap cannot complete.
You get a deposit address on the Ethereum (ERC-20) network. Send your USDC to it from any wallet, in one payment of at least 10 USDC. No account, no email, nothing to install.
Your deposit needs 12 confirmations on Ethereum (ERC-20), about 3 minutes. We screen it before the exchange starts, then send USDT to your address and post the transaction hash on your order page.
Liquidity is the big one. USDT has deeper order books and more trading pairs on virtually every exchange and DEX in existence. If you're sitting on USDC and you want to trade into some altcoin that only has a USDT pair, you need Tether. It's the universal trading currency of crypto. Converting USDC to USDT before placing a trade is like exchanging your euros for dollars before walking into an American store. The store technically exists either way, but the dollar version has way more stuff on the shelves.
Platform compatibility comes up constantly. Some DeFi protocols, yield farms, and lending pools offer better rates or more options for USDT than USDC. Some exchanges only support USDT for certain features. Some payment processors or P2P markets price everything in Tether. If the tool you want to use speaks USDT, you swap into USDT. It takes two minutes and costs basically nothing.
Geographic reality plays a role too. In large parts of Asia, the Middle East, Africa, and Latin America, USDT is the de facto digital dollar. Local OTC desks, merchant payments, peer to peer transfers, remittances: they all run on Tether. If you're holding USDC and you need to pay someone in a market where Tether is king, the fastest path is a swap, not a lecture about which stablecoin has better reserve attestations.
Risk diversification sounds fancy but it's just common sense. Holding all your stablecoins in one issuer means you're trusting one company, one set of bank relationships, one regulatory jurisdiction. Splitting between USDC and USDT means if something weird happens to Circle or Tether (a bank freeze, a regulatory action, a reserve question), your entire stablecoin position doesn't wobble at once. Smart money holds both and swaps between them depending on what they need at the moment.
Fee savings are real when you're moving money around. USDT on TRC-20 has some of the lowest transfer fees in all of crypto. If you're holding USDC on Ethereum and you want to send stable value somewhere cheaply, swapping to USDT on Tron first can save you more in gas fees than the swap itself costs. It's a two step process that ends up cheaper than the one step alternative.
Privacy matters. Centralized exchanges that let you swap stablecoins also collect your passport, your address, your transaction history, and a detailed map of your financial life. CoinVast asks for a receiving address and nothing else. You provide a wallet, send USDC, and receive USDT. No account, no personal data, no compliance team reviewing your swap of one dollar for another dollar.
10 USDC. That's ten dollars. Enough to test the entire flow without losing sleep over it. Send the minimum, watch your USDT arrive, and then decide if you want to go bigger. The whole test run takes a few minutes and costs you roughly a nickel in spread.
Very close to 1:1. Both coins are pegged to the US dollar, so the exchange rate stays within a tiny band. CoinVast applies a flat 2% spread, locked the moment you create the swap. For 100 USDC, you'd receive approximately 98 USDT. That's the entire cost. No hidden fees, no withdrawal charges, no "processing fee" that appears at the last second.
TRC-20 (Tron) is the fastest and cheapest. Transfers cost fractions of a cent and confirm in seconds. ERC-20 keeps your USDT on Ethereum, which makes sense if you're planning to use it in Ethereum DeFi protocols or your wallet is already on that chain. TON is the pick if you live in the Telegram ecosystem and want your stablecoins right there. Whatever you choose, make absolutely sure your receiving wallet supports that exact network. Sending USDT to the wrong network is the one mistake that can actually cost you money.
Depends on the network you're sending USDC from and the network you're receiving USDT on, but the whole thing usually wraps up in under 10 minutes. CoinVast waits for enough confirmations on the USDC side to consider the deposit final, then sends your USDT. TRC-20 payouts arrive almost instantly. ERC-20 takes a couple minutes depending on gas. You'll spend more time double checking your wallet address than actually waiting.
None. CoinVast is non-custodial. You provide your USDT receiving address, send USDC to the deposit address, and the swap happens automatically. No email, no phone number, no uploading a photo of yourself holding a sign like you're auditioning for a reality show. Automated pre-screening runs on transactions for compliance, but you never create an account or hand over personal data.
The rate is locked the instant you create the swap: the rate you see is the rate you get. CoinVast quotes one number, a flat 2% spread over the mid-market rate, with no floating option and no second tier to weigh up. Since both coins hover around $1, the underlying rate barely moves anyway, but you don't have to think about that. You see the exact USDT figure before you send, it's locked to the penny, and that's the amount that lands in your wallet.
Yes. The reverse pair works with the same non-custodial, no-KYC flow. Select USDT as your send coin (on TRC-20, ERC-20, or TON), paste your USDC address, and go. Same near 1:1 rate, same flat 2% spread locked at quote time, same lack of paperwork. Useful for when you need to rotate back into the regulated stablecoin for DeFi yields or institutional compatibility.
You absolutely can, and for some people that's the right move. DEXes like Uniswap or Curve handle billions in stablecoin swaps and offer extremely tight spreads. But they require gas fees, wallet interactions, and some familiarity with on-chain mechanics. Centralized exchanges have even tighter spreads but require full KYC, account creation, and custody of your funds. CoinVast sits in the middle: no account, no KYC, no custody of your coins, and you don't need to know how to interact with a smart contract. You just paste an address and send.
CoinVast is non-custodial, meaning it never holds your funds beyond the time needed to complete the swap. You send USDC, the swap executes, and USDT goes to the wallet address you provided. There's no account balance sitting on a server waiting to get hacked. The main thing you need to get right is your receiving address and network. Triple check those before confirming. Once a blockchain transaction goes through, there's no customer service number that can undo it.
Setting it up takes under a minute. The blockchain handles the rest.
