Swap USDC to ATOM

Exchange USDC from Base into ATOM on Cosmos Hub. The provider waits for the USDC deposit before arranging the ATOM payout on the destination network. Track those as separate transactions rather than using a sending-chain confirmation as proof of receipt.

USDC (Base) to Cosmos (Mainnet)

You send: USDC (Base)USDC · base
You receive: Cosmos (Mainnet)ATOM · Mainnet

Enter your amount to check live availability for USDC on base → ATOM on Mainnet. A provider quote is required before you can create a swap.

Address and network checks

Use the order’s Base deposit address for USDC, and your own Cosmos Hub receiving address for ATOM. Keep the refund address on Base; the payout address is not automatically a valid refund destination.

Sending USDC

Switch the wallet to Base. ETH on Ethereum mainnet cannot pay the normal gas fee for a separate token transfer on Base. Confirm the destination supports the exact USDC version returned by the provider. In particular, do not assume USDC, USDC.e and Binance-Peg representations are interchangeable.

For a standard self-custody transfer on Base, allow for network fees in ETH, separately from your USDC 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 USDC on base. The refund is sent in USDC on base; verify that your refund wallet supports this exact asset and network.
