POWER TOOLS FOR LOTTERIES

VERIFIABLE RANDOMNESS

Earn your players trust by proving them that your lottery is not rigged.

FUN TO PLAY

SECURITY BUILT-IN

AWARD-WINNING TECHNOLOGY

Back your lottery with a trusted algorithm.

RELY ON PROOFS, NOT PROMISES

The old broken way

/* You generate randomness using an unsafe API like
random.org. Even if the website tells you that they
are using quantum technology under the hood to
generate the randomness, you have no way to verify
this claim. They could easily send you a rigged
number for your lottery to claim the prize for
themselves and you wouldn't know about it.
Random.org founder himself admits this is possible. */

const unsafeApi = 'random.org/api/get-random-numbers'
const randomNumbers = await fetch(unsafeApi)

console.log(
`The winning numbers are: ${randomNumbers}.
However, we cannot prove you that these numbers are
random so please trust us. 🙏`
)

/* Your players have no way to verify that your
lottery is not rigged. Some people may not even
want to participate in your lottery at all for this
particular reason, meaning that you are missing on
potential customers. */

The Random.win way

/* You know the numbers you are getting cannot be
rigged because you fetch them directly from our
blockchain algorithm whose code is public, audited,
GLI-certified, and cannot be modified by anyone,
not even by us. */

const randomNumbers = await ethereum.readContract({
address: randomWinContractAddress,
abi: randomWinContractAbi,
functionName: 'getRandomNumbers',
args: ['your-lottery-identifier']
})

console.log(
`The winning numbers are: ${randomNumbers}`
)

/* Anyone can verify your winning numbers on the
blockchain in 10 seconds if they don't trust you */
