The following smart contract is a base reward pool contract that allows users to stake tokens and earn rewards. It includes functions for staking, withdrawing, and claiming rewards. The contract also allows for the addition of extra rewards and the queuing of new rewards. The contract uses SafeMath and SafeERC20 libraries for safe arithmetic and token transfers.
