Swap Sonic to Polygon without KYC

Enter the S amount on this page, choose an offer, paste your POL address and send your S 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 POL is paid directly to your wallet.

At the last update, 1 S ≈ 0.418576 POL (the best of 7 offers for 2,500 S). 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 40.1 S and the maximum about 12,535,093 S. Limits vary slightly between exchanges and follow market prices; the form tells you immediately if your amount is outside the range.

Usually around 12 min. Most of that is waiting for your S deposit to confirm on Sonic, which takes a few seconds. 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 Sonic 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 POL 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 Sonic network fee to send the deposit.

Yes. The reverse direction, POL to S, 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.
