AltoSwap never holds your funds: you send USDT to a one-time deposit address and the USDC is paid straight to the wallet you provide. There is no account, no email and no identity check at any step.

Your USDC is paid on Ethereum. Use an address that starts with 0x and is 42 characters long.

Type how much USDT you want to swap (minimum about 6.9 USDT). The USDC you will receive updates live.
A top no-KYC rate is already chosen for you. The form shows what you receive, how long it usually takes and the KYC rating of the route.

Send the exact amount to the deposit address on Tron. After it confirms (about 1-3 minutes), the USDC is sent to your address.
You send

You receive
USD Coin (USDC) is a US-dollar stablecoin issued by Circle and backed by cash and short-dated US Treasuries. It circulates on Ethereum, Solana, Base and many other chains.

No. AltoSwap holds no licence in Spain. It is a non-custodial aggregator: it never holds your coins, and each swap is carried out by the exchange or network on the route.
No. AltoSwap swaps crypto for crypto only. Buy your USDT first, then swap it here.
No. AltoSwap asks for no account, email or documents, and by default routes through exchanges rated A for KYC, which do not ask for them either.
Enter the USDT amount on this page, paste your USDC address and send your USDT to the deposit address shown. AltoSwap has no accounts and asks for no identity documents, and it routes your swap through exchanges rated A for KYC, meaning providers that do not run identity checks. The USDC is paid directly to your wallet.
At the last update, 1 USDT ≈ 0.975492 USDC (from 4 no-KYC offers compared for 500 USDT). Rates move with the market every few seconds, so use the calculator at the top of the page for the live rate on your exact amount.
The minimum is about 6.9 USDT and the maximum about 2,157,687 USDT. Limits vary slightly between exchanges and follow market prices; the form tells you immediately if your amount is outside the range.
Usually around 10 min. Most of that is waiting for your USDT deposit to confirm on Tron, which takes about 1-3 minutes. There is no verification step, so nothing else adds to the wait.
AltoSwap does not know who you are (no account, no email, no identity checks) and the default route uses no-KYC exchanges. Both Tron and Ethereum are public ledgers, though, so the transactions themselves are visible on-chain. For on-chain privacy, swap into a privacy coin such as Monero.
Your USDC is paid on Ethereum. Use an address that starts with 0x and is 42 characters long. Always use an address in a wallet you control and double-check the first and last characters before sending.
Everything. The exchange's spread, the Ethereum network fee for the payout and any service commission are already inside the quoted rate, so the amount shown is what you receive: exactly on a fixed rate, approximately on a floating rate. You only pay your own Tron network fee to send the deposit.
Yes. The reverse direction, USDC to USDT, works the same way and has its own page and live rate on AltoSwap. Each direction is quoted independently, so the two rates are not exact mirrors of each other.
