ATOM to ARB: questions and answers
How do I swap ATOM to ARB without KYC?
Enter the ATOM amount on this page, choose an offer, paste your ARB address and send your ATOM 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 ARB is paid directly to your wallet.
What is the ATOM to ARB exchange rate?
At the last update, 1 ATOM ≈ 8.54907 ARB (the best of 12 offers for 200 ATOM). 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 ATOM to ARB?
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.
How long does a ATOM to ARB swap take?
Usually around 12 min. 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.
Is swapping ATOM to ARB anonymous?
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.
Which ARB address should I use?
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.
What fees are included in the ATOM to ARB rate?
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.
Can I swap ARB back to ATOM?
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.
