What is Optimism?

Optimism (OP) is a Layer 2 scaling solution for Ethereum that uses optimistic rollups to make transactions faster and significantly cheaper than on Ethereum mainnet. Optimism is known for its retroactive public goods funding model, which directs network revenue toward open-source projects that benefit the ecosystem. OP is the governance token used for voting on protocol decisions and treasury allocation. Major DeFi protocols including Aave, Uniswap, and Synthetix are deployed on Optimism.

What is Cosmos?

Cosmos (ATOM) powers an ecosystem of independent, interconnected blockchains known as the 'Internet of Blockchains.' Using the Inter-Blockchain Communication (IBC) protocol, Cosmos enables different chains to transfer tokens and data between each other seamlessly. ATOM is used for staking, governance, and securing the Cosmos Hub — the central chain that coordinates the network. Many major projects including Osmosis, Celestia, and dYdX have been built using Cosmos SDK technology.

How to Exchange Optimism to Cosmos

Select OP and ATOM

Pick OP in “You send” and ATOM in “You get”, then enter the amount. The box shows how much ATOM you get and the minimum OP for this pair.

Enter Cosmos Address

Paste the Cosmos Hub address that should receive the ATOM (it starts with cosmos1). Add a Memo only if that address belongs to an exchange account. Then enter the OP Mainnet address you send OP from; a refund, if ever needed, goes there.

Send Optimism

Send exactly the amount shown from your own OP Mainnet wallet to the one-time deposit address. Keep a little ETH on OP Mainnet in that wallet for the network fee.

Receive Cosmos

Your ATOM is usually paid out 5–15 minutes after you send your OP, and Cosmos Hub then confirms it in under a minute. Follow each step on the status page with your swap ID.

OP to ATOM: questions and answers

Everything you need to know about exchanging OP to ATOM on GhostSwap.

How long does it take to swap OP to ATOM on GhostSwap?

Most OP to ATOM swaps are paid out within 5–15 minutes: the OP deposit needs about a minute to confirm on OP Mainnet, then the ATOM is sent to your wallet, and Cosmos Hub confirms the payout in under a minute. Busy networks can add a few minutes.

How much is 1 OP in ATOM?

1 OP is worth about 0.069016 ATOM at the market rate, before fees (market prices, 8 Oct 2026). GhostSwap's quote in the exchange box already includes the service fee and the ATOM network fee. The rate floats with the market until your OP deposit confirms, so the exchange box shows the exact amount before you send.

Do I need KYC or an account to exchange OP to ATOM?

No. GhostSwap has no accounts: you paste the Cosmos Hub address that should receive the ATOM, send OP from your own wallet, and the ATOM goes straight to that address. No email, phone number or ID upload.

What are the fees for converting Optimism to Cosmos?

The GhostSwap fee is already included in the rate in the exchange box, so the ATOM amount you see is what you receive. On top of that, your wallet needs a little ETH on OP Mainnet to pay the OP Mainnet network fee for sending OP.

What wallet should I use to receive ATOM?

To receive Cosmos from your swap, we recommend using Keplr, Trust Wallet or Vultisig. Make sure your wallet supports the Cosmos Hub network before starting the exchange. Double-check your ATOM address before confirming, cryptocurrency transactions cannot be reversed.

What format is the ATOM address?

Use a Cosmos Hub address: it starts with cosmos1. Copy it from your wallet and paste it; never type it by hand.

Do I need a Memo to receive ATOM?

Only if the ATOM goes to an exchange or custodial account that gave you a Memo; enter it in the field shown in the exchange box. A personal ATOM wallet does not need one.

Can I track my OP to ATOM swap?

Yes. After initiating your swap, GhostSwap provides a transaction status page where you can monitor progress in real-time. You can also track your OP payment on Optimistic Etherscan (https://optimistic.etherscan.io) and your incoming ATOM on Mintscan (https://www.mintscan.io/cosmos).

Is it safe to exchange OP for ATOM on GhostSwap?

GhostSwap is non-custodial: there is no account balance holding your coins. Your OP deposit is converted and the ATOM is sent straight to the Cosmos Hub address you enter, so check that address twice, Cosmos Hub transfers cannot be reversed.

How does a cross-chain OP to ATOM swap work?

Optimism lives on OP Mainnet and Cosmos on Cosmos Hub, two separate blockchains. Instead of a bridge, GhostSwap takes your OP on OP Mainnet and pays native ATOM on Cosmos Hub, so you never hold a wrapped token or pay bridge fees.

What happens if my OP to ATOM exchange fails?

If a swap cannot be completed, the OP is refunded to the OP Mainnet address you entered as the sender address. If something looks stuck, contact support with your swap ID from the status page. Most problems come from sending a different amount than shown or using an address on the wrong network.
