Gacha-style NFT reveals on Solana blockchain. NFT ≠ JPEG, NFT = dopamine🧠

What it does

From the project README:

1. **No instant reveals** You have to wait before you can see your NFT, and that waiting kills the thrill and breaks the hype. 2. **No clear win or loss** You pay to mint but don’t know if you got something rare or just a common NFT. Mints feel flat—no thrill, no FOMO. 3. **Low liquidity** If you miss out on a rare drop, you can’t sell or trade right away—you’re stuck waiting for a buyer.

Dapp: devnet deploy pending

⏳ Devnet deploy pending — goes live when the devnet wallet is topped up. This fork's own dapp is not deployed yet, so there is no program address or transaction to show. It is queued in dapp-queue.txt; once devnet SOL is available it is deployed, exercised with real devnet transactions, and this section switches to the live dapp at /dapps/dopamint-fun/. Until then, the lesson and step-by-step guide below are complete, and you can run it locally with the commands below.
