In shortTo swap Tether (Polygon) (USDT) to Filecoin (FIL) without KYC, enter the amount, paste your FIL 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 FIL 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 FIL on Filecoin is already included in the rate.
Because USDT is pegged to the US dollar, this swap is effectively buying Filecoin at its dollar price, minus the spread, without opening an exchange account, passing verification or waiting for a withdrawal.
Your FIL is paid on Filecoin. Use an address that starts with f1. If your wallet or exchange gave you a memo, enter it as well; for a personal wallet it can usually be left empty.
Type how much USDT you want to swap (minimum about 6.9 USDT). The FIL 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 Filecoin address where you want to be paid, plus a memo if you were given one. 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 FIL 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
Filecoin is a decentralised storage network in which FIL pays storage providers for keeping data available.

Enter the USDT amount on this page, paste your FIL 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 FIL 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 FIL 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 Filecoin 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 FIL is paid on Filecoin. Use an address that starts with f1. If your wallet or exchange gave you a memo, enter it as well; for a personal wallet it can usually be left empty. 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 Filecoin 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, FIL 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.
