If an attendee reports a lost NFT Ticket, verify their purchase details first. Since are digital assets stored in a blockchain wallet, they can't be lost in a traditional sense. Advise the attendee to access their digital wallet where the NFT Ticket is stored. If they have issues accessing their wallet, they should follow the wallet provider's recovery process. In cases where the ticket is irrecoverable, assess the situation and your event's policy on such matters. You may reissue the ticket to the attendee's new wallet address after proper verification. It's important to have a clear policy for such scenarios to guide your response.
