Preparation
Do you know you can always contact the Binace Oracle team for assistance if you come across any issues using our service. Please feel free to drop us a note if you are interested.
For testing on the BSC testnet, you can go to the faucet and get some tBNB.
Preparation
To connect to Binance Oracle VRF, you need to prepare your smart contract to use the VRF. This involves importing the Binance VRF library contracts (provided below) and calling the requestRandomWords function with the required parameters. You also need to set up a callback function to handle the return value from the VRF. Once you have received the random number from the VRF, you can use it in your dApp.
