In shortTo swap Cosmos (ATOM) to Tether (Polygon) (USDT) without KYC, enter the amount, paste your USDT address and send your ATOM to the one-time deposit address. AltoSwap compares 20+ exchanges for this pair, keeps the no-KYC ones by default and routes your swap to the offer that pays the most USDT. 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.
Swapping into USDT moves value into a dollar-pegged asset without leaving crypto. It is the no-account way to lock in the current ATOM price: no order book, no verification, and the USDT lands in a wallet you control.
Your USDT is paid on Polygon PoS. Use an address that starts with 0x and is 42 characters long.
Type how much ATOM you want to swap (minimum about 2.2 ATOM). The USDT you will receive updates live.
The top no-KYC offer is preselected. Open 'All offers' to compare fixed and floating rates, speed and each exchange's KYC rating.
Paste the Polygon PoS address where you want to be paid. A refund address for your ATOM is optional but recommended.
Send the exact amount to the deposit address on Cosmos Hub. After it confirms (under a minute), the USDT is sent to your address.

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.

Enter the ATOM amount on this page, choose an offer, paste your USDT address and send your ATOM to the deposit address shown. AltoSwap has no accounts and asks for no identity documents, and by default it only shows exchanges rated A for KYC, meaning providers that do not run identity checks. The USDT 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 ATOM to USDT rate for the amount you enter.
The minimum is about 2.2 ATOM and the maximum about 687,000 ATOM. 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 ATOM deposit to confirm on Cosmos Hub, which takes under a minute. 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 Cosmos Hub and Polygon PoS 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 USDT is paid on Polygon PoS. 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 Polygon PoS 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 Cosmos Hub network fee to send the deposit.
Yes. The reverse direction, USDT (Polygon) to ATOM, 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.
