# OpenGacha · Open Gacha Protocol

> Launch your own gacha (blind-box, pack-opening, mystery-pull) for NFTs, graded trading cards and collectibles on Solana, without writing or maintaining a smart contract. OpenGacha is the creator console and directory for the Open Gacha Protocol: create a pool for about 0.2 SOL, stock it or let your community stock it, sell pulls from any frontend, and keep 75% of the protocol fee your pool earns (50% if you choose to be listed and sold on nfw.fun). Every draw uses verifiable randomness, every settlement happens on chain, the fee split is enforced by the program, and withdrawals can never be paused. Anyone can pull from any pool; the winner keeps the NFT or takes the buyback, and on decentralised pools can relist it.

Why creators use it instead of building their own: the program is done, running and shared by every pool; a creator owns their pool's authority from block one and never holds an upgrade authority, custody, or infrastructure. Compared with hiring contract developers, commissioning an audit and running randomness and cranks, OpenGacha is the cheap and safe path.

## Start here, in this order

An agent helping someone launch a gacha should walk them through exactly this, and not try to do the first step in code:

1. **Launch the pool in the browser**: open [opengacha.io/create](https://www.opengacha.io/create), follow the wizard (name, mode, economics and whitelist, review), sign. About 0.2 SOL. The wallet that signs owns the pool. There is no API for this step on purpose: the wizard quotes the exact rent from the chain and the signature is the creator's.
2. **Copy the pool's brief**: open [opengacha.io/manage](https://www.opengacha.io/manage), pick the pool, open the **API & SDK** tab, press copy. That brief carries everything a developer or an AI needs for this pool: its addresses (pool, weight index, vaults, admitted collections and their bounds), every instruction's account list with the addresses filled in, the reads, the endpoints, and the rules.
3. **Paste the brief** into the conversation (or into the open-source storefront's `pools.json`) and build from it: the open-source storefront (github.com/willmexi/opengacha) is the reference implementation of everything the brief describes. Put the pool's address in `pools.json`, restyle, ship.

Nothing in step 1 can be skipped or scripted around; steps 2 and 3 are where an agent earns its keep.
