The illustrative proof of concept app gamifies the minting of an on-chain NFT, providing a speedbump to mass minting by any single actor. It accomplishes this by requiring that the player randomly draws a prime number between 1 and 100 before being able to mint a NFT. Being able to win a portion of the accumulated balance provides the risk/reward element of the game. The gameplay is designed to teach basic concepts of Ethereum and blockchain technology to new users. ๐
The smart contract
YourContract.sol
contains detailed comments regarding the relevant smart contract considerations for this build
๐ You can find the core smart contract YourContract.sol
in packages/hardhat/contracts
. You will need to update this file for your own subscrition ID (check out the constructor within the YourContract.sol
file) to make it work.
Go here (https://vrf.chain.link/) to create and manage your subscriptions (i.e. add your newly deployed smart contract to the list of consumers).
๐ฑ You will need to deploy it to Goerli to make it work
