A machine can only open for a brand new coin. The creator launches the coin and its machine in one transaction, so nobody can trade the coin before the machine exists.

What you choose

  • Name, symbol and image. They go into the coin’s own metadata.
  • Quote token. The token your coin trades against: USDC, SOL, a registered stock token or another registered Solana token. It cannot change later. Buyers still pay for packs in USDC. Your holders’ Mega Pack rewards are paid in this token.
  • Starting liquidity. How many extra jackpots your seed funds. See Seed and jackpot.
  • Machine recharge (optional). Your creator fees buy the coin and refill the prize pool: all of them, or a part. See Machine recharge.
Everything else is fixed for every coin: 9 decimals, 1,000,000,000 coins, the app’s prize table, the trading fees and the move to DAMM v2 at graduation. A client built on the SDK may pass another valid prize table.

What happens in the launch transaction

  1. Meteora DBC creates the Token-2022 coin, with the Gabox transfer hook, and its bonding curve. It uses the quote token’s registered Gabox config.
  2. The hook program creates the coin’s account list. The hook needs it to run.
  3. initialize_pool checks the config, the coin, the hook and the prize table. It refuses a coin that has already traded.
  4. The seed buy is the coin’s first trade. It buys the seed coins straight into the prize pool.
With Machine recharge on, enable_self_sustaining runs right after initialize_pool. It makes the machine’s fee address the coin’s creator on Meteora. If any step fails, nothing happens.

What it costs

  • The seed, paid in the machine’s quote token. There is no swap at launch, so on a machine not quoted in SOL you must already hold that token. The seed buy pays the curve’s trading fee, but no pack fee.
  • SOL for account rent and the network fee.
You sign max_seed_quote_in, the most quote tokens the seed may spend, and max_seed_native_debit, the most SOL it may spend. The app shows the estimated launch cost before you sign.

Launch checks

The program checks that:
  • the config is the one Gabox registered for that quote token, with the Gabox fee terms;
  • the coin has 9 decimals, the fixed supply and the Gabox hook;
  • the curve is new and has had no trade;
  • the prize pool is empty before the seed;
  • the prize table is valid, and even the smallest possible buy on this curve pays every row at least one coin unit.

After launch

The coin’s market terms cannot change. The Gabox admin can later raise the prize table, but only to one that pays at least as much on average; a pack already bought keeps the table it was bought under. As creator, you can add more prize coins with fund_prizes (Fund prizes in the app). You can take them back later with withdraw_reserve (Withdraw prizes): never more than you added, never more than the free coins, and only while no pack is opening and no prize is owed. Only the creator can do either. The seed never comes back. As creator you earn part of every trade’s fee: 0.96% on the curve and about 0.72% after graduation, through your locked share of the pool. You do not earn pack fees on your own machine. See Referrals and earnings. With Machine recharge, all or part of these fees refill your prize pool instead. When the curve reaches its target, the coin graduates. See Transfer hook and graduation.
