## FAQ

### How long does it take to swap OP to CRO on GhostSwap?

When you exchange Optimism to Cronos on GhostSwap, the process typically takes about a minute on OP Mainnet for your OP to confirm on the OP Mainnet (Ethereum layer 2) network. Once confirmed, your Cronos is sent to your wallet and arrives within a few minutes on Cronos. Most OP to CRO swaps are paid out within 5–15 minutes after you send; network congestion can occasionally add time, and the status page shows each step.

### Do I need KYC or an account to exchange OP to CRO?

No. GhostSwap is a non-custodial, no-KYC exchange. You can convert Optimism to Cronos without creating an account, uploading ID documents, or providing any personal information. Just enter your Cronos wallet address, send your OP, and receive your CRO, that's it.

### What are the fees for converting Optimism to Cronos?

GhostSwap charges a small service fee that's already included in the exchange rate you see, there are no hidden fees. On top of that, OP Mainnet fees are usually a few cents, paid in ETH. The swap box shows the estimated amount of CRO after fees before you send. The rate floats, so the final amount can differ slightly if the market moves before your deposit confirms.

### What wallet should I use to receive CRO?

To receive Cronos from your swap, we recommend using Crypto.com DeFi Wallet or Trust Wallet. Make sure your wallet supports the Cronos network before starting the exchange. Double-check your CRO address before confirming, cryptocurrency transactions cannot be reversed.

### Can I track my OP to CRO 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 CRO on the Cronos explorer.

### Is it safe to exchange OP for CRO on GhostSwap?

Yes. GhostSwap is a non-custodial exchange, which means we never hold your funds or private keys. Your Optimism is converted and sent directly to your Cronos wallet address. Standard swaps need no account, email or ID, and all swaps run over encrypted connections.

### How does a cross-chain OP to CRO swap work?

Optimism runs on the OP Mainnet (Ethereum layer 2) network while Cronos runs on the Cronos network, they can't be sent directly to each other. GhostSwap handles the cross-chain conversion for you: you send OP to our temporary deposit address, we convert it, and send the equivalent CRO to your wallet. No bridge protocols or technical knowledge required.

### What happens if my OP to CRO exchange fails?

In the rare case of a failed exchange, your OP is refunded to the address you entered as the sender address. If something looks stuck, contact support with your swap ID from the status page. Most problems are caused by sending a different amount than shown or using an address on the wrong network.
