# Rewards

This document aims to allow external developers to integrate with Mito's LP Staking Rewards from within their dApps. We will only show the message examples, how will you integrate them within your dApp is your own choice. Documentation on broadcasting the transactions containing these messages can be found [here](https://docs.ts.injective.network/transactions/msgbroadcaster#msgbroadcaster--wallet-strategy).
