Networks and wallets for ATOM to ARB
Cosmos Hub mainnet (native ATOM)
Check whether the ATOM balance is on Cosmos Hub or represented through IBC on another chain. For a Cosmos Hub deposit, follow the provider’s address and memo instructions on the Hub.
Arbitrum One (ERC-20 ARB)
Check that the receiving service credits ARB on Arbitrum One specifically. If you plan to send it onward from self-custody, leave some ETH on Arbitrum One for fees.
Check ATOM deposit and ARB payout availability separately. The live service needs to accept your source network and offer the destination network that your ARB wallet expects.
How to convert ATOM to ARB
- Enter the ATOM amount to see the estimated ARB payout.
- Enter a receiving address on Arbitrum One · ERC-20 ARB and a refund address on Cosmos Hub mainnet. Check any destination tag your wallet requires.
- When the route accepts orders, review the exact amounts and follow the deposit instructions. Submit the ATOM transaction ID and use your private order link to track the ARB payout.
How to compare ATOM to ARB rates
For a rough pre-fee estimate, multiply the ATOM amount by the rate expressed in ARB per ATOM. Then compare the actual ARB payout for the same ATOM amount and network. Check whether the withdrawal fee comes out of what you send or is charged separately.
Swap Crypto has a $100 minimum. Estimates use market prices before fees. The order page shows the exact send and receive amounts, and your wallet may charge a separate network fee for sending the deposit.
