What is Gamba?

Gamba is a decentralized betting platform on Solana. It allows anyone to build on-chain casino games without deploying any backend code or providing any of their own liquidity.

When users play on your app you automatically collect royaltees.

Code example

Here's a very simple example where the player has a 50/50 chance of doubling their money. By changing the creator property to your own wallet address, all bets made in your app will earn you royaltees.

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>
  )
}
