Swap Sonic to Avalanche without KYC

Enter the S amount on this page, paste your AVAX address and send your S 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 AVAX 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 S to AVAX rate for the amount you enter.

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 5 to 30 minutes. 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 Avalanche C-Chain 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 AVAX is paid on Avalanche C-Chain. 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 Avalanche C-Chain 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, AVAX 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.
