Gamba is a decentralized betting platform on Solana. It handles all liquidity and randomness, allowing developers to focus on building games.

When users play on your app you will automatically collect royaltees.

Installation

If you want to create a Gamba project from scratch you can install our main package:

npm i gamba

Example

The following example is a simple game where the user has a 50/50 chance of doubling their money.

import React from 'react'
import { Gamba, useGamba } from 'gamba/react'

function DoubleOrNothing() {
  const gamba = useGamba()

  const play = async () => {
    // Request user to sign transaction
    const request = await gamba.play({
      bet: [0, 2], // 0x or 2x
      wager: 1e9 * 0.1, // 0.1 SOL
    })
    // Await the result
    const result = await request.result()
    // ... Visualize the result however you want
  }

  return (
    <>
      <button onClick={play}>
        Double or Nothing
      </button>
      {gamba.user.balance > 0 && (
        <button onClick={() => gamba.withdraw()}>
          Claim {gamba.user.balance / 1e9} SOL
        </button>
      )}
    </>
  )
}

function App() {
  return (
    <Gamba creator="<PUBLIC KEY>">
      <DoubleOrNothing />
    </Gamba>
  )
}
