How it differs from a new-coin machine
Which coins can have one
The program checks the coin when a machine opens. It accepts:- a classic SPL token with no freeze authority; or
- a Token-2022 token with no mint authority and no freeze authority. Its only extensions may be metadata and group extensions. A transfer hook is allowed only when it does nothing, as on a graduated Gabox coin.
One coin, many machines
Anyone can open a machine on a coin that passes these checks, as many times as they like. Each machine has its own address, its own prize pool, its own prize table and its own page athttps://gabox.fun/<machine address>. Two machines on the same coin share only the coin.
So a machine’s name tells you little. Check the coin’s address before you buy. In the app, coins on Jupiter’s verified list, and $GABOX, carry a blue mark.
Opening one
The creator chooses two things:- The top prize. In the app, 3×, 5×, 8×, 10×, 20×, 50× or 100× the pack coins. Each choice comes with its own table of Common, Rare, Epic and Mythic rows. Every table pays back about 0.95× to 0.955× of a pack on average, so no choice is a better deal. A higher top prize comes with smaller wins most of the time. The 8× choice is the app’s default table.
- The seed. The creator’s own coins. They move into the prize pool when the machine opens. There is no buy and no swap at launch. The program only needs a seed above zero. The app sizes the seed in US dollars and asks for at least $20 of the coin.
How a pack works
- You pay the pack price in USDC. Packs have a fixed range of USDC prices.
- The program takes the 2% pack fee from the price.
- The rest is swapped into the coin in the same transaction. In the app, Jupiter finds the swap route. The app sets the fewest coins you accept,
min_net_tokens, so the purchase fails rather than buy fewer. - All the bought coins go into the prize pool. They are your pack coins: every prize is a multiple of them.
- From here the pack works like any other. Your draw keeps its own copy of the prize table, MagicBlock picks the ticket, and the prize goes to your coin account. The prize pool caps a prize the same way. See Opening a pack and Always funded.
Where the pack fee goes
The pack fee is 2% of the pack price. It is inside the price and paid in USDC.
A Fan coin machine has no Gabox market, so its creator earns no trading fee. Instead the creator earns part of every pack. Referral links work as on new-coin machines. Each wallet claims its USDC fees from its profile. See Referrals and earnings.
Keeping or selling a prize
A prize arrives as the coin. You can keep it. In the app you can also sell it for USDC. The app swaps it through Jupiter. The swap includes a 0.15% Gabox fee. A sale is your own trade at the market price, so its result can be lower than the value the app showed.Funding and withdrawing prizes
Only the machine’s creator can add more prize coins (Fund prizes in the app) and take them back (Withdraw prizes). The rules are the same as on a new-coin machine: never more than the creator added, never the seed, and only while no pack is opening and no prize is owed. See After launch.Gifts
You can send a pack on a Fan coin machine as a gift. The gift holds its USDC until it is opened. The opening pays the same 2% pack fee as a purchase. See Gift packs.In the app
- Launching. “Fan coin” on the launch page opens one. It is open to everyone.
- The machine list. A Fan coin machine shows on the home list once its free prize pool is worth at least $10. Its own page works from the start.
- The leaderboard. It ranks wallets by packs opened only. It does not list the coin’s largest holders, because most of them never used this machine.
