Convex Rewards Token

This is a Solidity smart contract for a reward pool where users can stake a specified token and earn rewards in a different token. The contract keeps track of staked balances and rewards earned. The reward rate is determined based on the duration and the total supplied tokens. The contract has a reward manager who can add extra rewards and clear them. Users can stake and withdraw their tokens, and the contract emits events when a user stakes, withdraws or is rewarded.

Booster is a Solidity smart-contract that provides incentives to Crv stakers, native token stakers, and users who spend gas to make calls. It allows users to deposit and withdraw funds from different pools, and also sets platform fees and treasury values. The contract also contains setter functions to change the owner, fee manager, and other system parameters.
