In shortTo swap Cosmos (ATOM) to Arbitrum (ARB) without KYC, enter the amount, paste your ARB address and send your ATOM to the one-time deposit address.

Cosmos and Arbitrum live on different blockchains, and this swap uses the native assets on both, with no bridge contract and no wrapped token. The exchange receives ATOM on Cosmos Hub and pays out ARB on Arbitrum One.
Your ARB is paid on Arbitrum One. Use an address that starts with 0x and is 42 characters long.
Type how much ATOM you want to swap (minimum about 2.2 ATOM). The ARB you will receive updates live.
The best 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 Arbitrum One address where you want to be paid. A refund address for your ATOM is optional but recommended.
Send the exact amount to the deposit address on Cosmos Hub. After it confirms (under a minute), the ARB is sent to your address.

Enter the ATOM amount on this page, paste your ARB address and send your ATOM 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 ARB 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 ATOM to ARB rate for the amount you enter.
The minimum is about 2.2 ATOM and the maximum about 687,000 ATOM. 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 ATOM deposit to confirm on Cosmos Hub, which takes under 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 Cosmos Hub and Arbitrum One 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 ARB is paid on Arbitrum One. 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 Arbitrum One 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 Cosmos Hub network fee to send the deposit.
Yes. The reverse direction, ARB to ATOM, 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.
