# Can I sell NFTs minted on Universe on other platforms?

Yes, for instance, an NFT minted on **OpenSea** can be sold on **Universe** and vice versa.

**Note**— If listed and sold on one platform, you will not be able to sell that NFT again on another platform.

All sales and transfers on the blockchain are **final**. There are no tools to reverse transactions. You can always use block scanners such as [Etherscan](https://etherscan.io/) to audit or verify successful transactions. Anything that says '[pending](https://docs.universe.xyz/universe-basics/wallet-faqs/my-transaction-is-stuck)' has yet to be confirmed 'on chain'.
