Urgently solana developer must be mastered in Rust just in 2 days!

phase 1 you buy a golden ticket NFT (same for all)
phase 2 or "reveal day", you exchange your ticket with the real NFT

until the reveal day you don't know which NFT you've got

my idea of the approach is:
- you mint the ticket (minting of tickets should be available only in pre-defined time slots)
- reveal day you send the ticket to a wallet
- wallet check ticket against a whitelist
- if check is ok wallet send you the first element in queue of a collection he already own (pre-generated or minted on the spot, no preferences)
