In shortTo swap Tether (Polygon) (USDT) to USD Coin (Solana) (USDC) without KYC, enter the amount, paste your USDC address and send your USDT to the one-time deposit address. AltoSwap compares 20+ exchanges for this pair, keeps the no-KYC ones by default and picks one of the best rates for you. No account, email or ID is needed.
Rates come from live exchange quotes and refresh automatically. Page content reviewed by the AltoSwap team on . How we produce and check these pages.
There is no route for USDT to USDC without an exchange at the moment, so this swap goes through an exchange.
You pay your wallet's own network fee to send USDT on Polygon PoS. The network fee for paying out USDC on Solana is already included in the rate.
Both assets are pegged to the US dollar, so the rate stays close to 1:1. What you pay is the exchange's spread and the network fees, which is why comparing 20+ providers matters most on pairs like this one.
Your USDC is paid on Solana. Use an address that is a 32-44 character base58 string.
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.
Paste the Solana address where you want to be paid. A refund address for your USDT is optional but recommended.
Send the exact amount to the deposit address on Polygon PoS. After it confirms (about 1-3 minutes), the USDC is sent to your address.
You send
Tether (USDT) is the largest US-dollar stablecoin by market capitalisation. It is issued on many blockchains, so the network you pick must match the network your wallet or exchange expects.
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.

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.
The rate moves with the market every few seconds and depends on the amount. The calculator at the top of this page requests live quotes from 20+ exchanges and shows the best current USDT to USDC rate for the amount you enter.
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 5 to 30 minutes. Most of that is waiting for your USDT deposit to confirm on Polygon PoS, 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 Polygon PoS and Solana 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 Solana. Use an address that is a 32-44 character base58 string. 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 Solana 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 Polygon PoS network fee to send the deposit.
Yes. The reverse direction, USDC (Solana) to USDT (Polygon), 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.
