Address and network checks
Use the order’s Arbitrum One deposit address for ARB, and your own Cosmos Hub receiving address for ATOM. Keep the refund address on Arbitrum One; the payout address is not automatically a valid refund destination.
Sending ARB
Choose Arbitrum One using the Mainnet option shown in this directory. Follow the selected provider’s exact deposit instructions before sending. Select the Arbitrum network for this listed ARB asset and retain ETH on that network for an ordinary wallet transfer. Holding ARB does not by itself pay the ETH gas fee.
For a standard self-custody transfer on Arbitrum One, allow for network fees in ETH, separately from your ARB balance. Wallet sponsorship and exchange withdrawal charges can differ; check the sending wallet’s final fee.
Receiving ATOM
Choose Cosmos Hub using the Mainnet option shown in this directory. Follow the selected provider’s exact deposit instructions before sending. Use the Cosmos Hub ATOM network specified by the order. An ATOM representation reached through IBC on another chain is not automatically a compatible deposit. This listed ATOM/Mainnet option is marked for an extra ID by the provider directory. Enter the receiving service’s required memo or extra ID. Use 0 only if your receiving wallet requires none. This flag does not mean every Cosmos Hub wallet requires a memo.
Refund address for this pair
Enter a refund address that accepts ARB on Mainnet. The refund is sent in ARB on Mainnet; verify that your refund wallet supports this exact asset and network.
Swap the other direction: ATOM to ARB
