OP to S: questions and answers
How do I swap OP to S without KYC?
Enter the OP amount on this page, choose an offer, paste your S address and send your OP 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 S is paid directly to your wallet.
What is the OP to S exchange rate?
At the last update, 1 OP ≈ 2.61433 S (the best of 9 offers for 1,000 OP). 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.
What are the minimum and maximum for OP to S?
The minimum is about 16.1 OP and the maximum about 5,027,177 OP. Limits vary slightly between exchanges and follow market prices; the form tells you immediately if your amount is outside the range.
How long does a OP to S swap take?
Usually around 12 min. Most of that is waiting for your OP deposit to confirm on OP Mainnet, which takes about a minute. There is no verification step, so nothing else adds to the wait.
Is swapping OP to S anonymous?
AltoSwap does not know who you are (no account, no email, no identity checks) and the default route uses no-KYC exchanges. Both OP Mainnet and Sonic are public ledgers, though, so the transactions themselves are visible on-chain. For on-chain privacy, swap into a privacy coin such as Monero.
Which S address should I use?
Your S is paid on Sonic. 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.
What fees are included in the OP to S rate?
Everything. The exchange's spread, the Sonic 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 OP Mainnet network fee to send the deposit.
Can I swap S back to OP?
Yes. The reverse direction, S to OP, 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.
