### FAQ

<AccordionGroup>
  <Accordion title="What happens if some of the transactions fail?">
    **Fiat purchases** <br />
    When a user submits an order, Crossmint puts a hold on their credit card and attempts the purchase of the NFTs. If the transaction fails, the funds are released instantly (though it may take some time to be reflected on the bank statement) so the customer is never charged.

    If an order results in a mix of successful and failed purchase attempts, Crossmint will only charge for the transactions that went through and return the rest instantly. Users will receive an email receipt with the final transaction amount.<br /><br />
    **Crypto purchases**<br />
    If a transaction fails, Crossmint will return the full amount to the buyer. Any gas fees incurred will be subsidized by Crossmint.

  <Accordion title="Do all NFTs must be on the same blockchain?">
