If you're having trouble transferring an NFT from your Slushy wallet, it might be locked in a Kiosk, which restricts transfers. To fix this, go to the marketplace where you listed the NFT—like Sui Marketplace or Topaz—and exit the Kiosk to regain full control. Once unlocked, try the transfer again. If problems persist, reach out to Slushy support with your NFT ID and transaction hash for assistance.

If you minted or received it via a project that uses Sui Kiosk (like some marketplaces or minting dapps), chances are it’s locked inside a kiosk. Kiosk NFTs can’t be transferred normally via Slushy or any basic wallet transfer.

You should try transferring it through Tradeport from 'my items'. It's important to know that kiosk NFTs can't be transferred directly, which might be the issue you're facing.
