How to generate random numbers

True randomness is a hard topic in computer science, and it is difficult to achieve all by yourself. When randomness is key to your project, we advise you to use a reputed Random Number Generator (RNG).

What is an RNG?

By producing sequences of numbers that cannot be predicted, RNGs ensure fairness and uniqueness in blockchain projects. This enhances the integrity and trustworthiness by preventing manipulation and ensuring equitable results.

What does it mean for Chiliz Chain developers

By incorporating RNGs, sports & entertainment projects can significantly boost the trust, excitement, and fairness of what they offer.

How to do it using Pyth?

Chiliz Chain's testnet "Spicy" supports Pyth's Entropy.

Entropy allows developers to quickly and easily generate random numbers on the blockchain for applications such as NFT mints, gaming, and more. Through the Solidity SDK, this enables developers to easily integrate RNG into their EVM applications.

Use the following address to use Entropy using Chiliz.
