What wallet should I use to receive SEI?

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 Sei wallet address. We don't store personal data, and all swaps are processed through secure, encrypted connections.

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

Optimism runs on the Optimism network while Sei runs on the Sei 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 SEI to your wallet. No bridge protocols or technical knowledge required.

What happens if my OP to SEI exchange fails?

In the rare case of a failed exchange, GhostSwap will automatically attempt to refund your OP to the refund address you provided. If you didn't provide a refund address, or if you need assistance, our support team is available to help resolve the issue. Most problems are caused by sending the wrong amount or using an incompatible wallet address.
