### FAQs

<Accordion title="Does the NFT type need to be the same for all NFTs in a multiple NFT transaction?">

<Accordion title="Can I buy NFTs from different collections in a single transaction?">
  No, currently Transak allows buyers to only buy multiple NFTs of the same collection.
</Accordion>

<Accordion title="Does the blockchain need to be the same for all NFTs in a group?">
  Yes. All NFTs in a transaction need to be part of the same blockchain.
</Accordion>

<Accordion title="How many NFTs can be grouped into a single order?">
