Using RNDFusion Hub

We are currently Avalanche Testnets and on Sepolia soon!

Create the interface

interface RndFusion {
    function RequestRandomNumber(uint256) external payable;
}

Define the interface

 RndFusion rndFusion;

Define the interface and contract address

 address rndFusionAddress = 0x748E11Bcabdd0aAf06e9618161061E04F417844A;

Set the contract address in the constructor

 constructor() {
        rndFusion = RndFusion(rndFusionAddress);
    }

(OPTIONAL) Create a function to set the address after deployment

  function SetRNDAddress(address _address) public {
        //Access controll (only owner should be allowed)
        rndFusionAddress = _address;
        rndFusion = RndFusion(rndFusionAddress);
    }

Call the RND fusion contract

    rndFusion.RequestRandomNumber{value: msg.value}(requestID);

Create a function for the callback

 function fulfillRandomWords(uint256 _requestId, uint256 _randomNumber) public {
        require(msg.sender == rndFusionAddress, "Not RNDFusion address");
        //Continue with your code using the request ID and random number
    }
