Enter the ETH amount on this page, paste your OP address and send your ETH 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 OP is paid directly to your wallet.
At the last update, 1 ETH ≈ 20,318.8 OP (the best of 2 no-KYC offers for 0.1 ETH). 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 0.00182 ETH and the maximum about 569 ETH. Limits vary slightly between exchanges and follow market prices; the form tells you immediately if your amount is outside the range.
Usually around 14 min. Most of that is waiting for your ETH deposit to confirm on Arbitrum One, which takes about 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 Arbitrum One and OP Mainnet 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 OP is paid on OP Mainnet. 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 OP Mainnet 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 Arbitrum One network fee to send the deposit.
Yes. The reverse direction, OP to ETH (Arbitrum), 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.
