# Introduction

These docs are a comprehensive guide to the [88mph protocol v3](https://88mph.app/), to help end-users and developers.

The protocol codebase is open-sourced and hosted on [Github](https://github.com/88mphapp). It's maintained by 88mph core contributors and the [community](https://docs.v3.88mph.app/grants-funding). It has been fully audited several times by [security audits firms](https://docs.v3.88mph.app/developer-docs/security). In parallel, 88mph maintains a [bug bounty program](https://immunefi.com/bounty/88mphv3/).

88mph is continuously iterating on the best way to operate a non-custodial, fully on-chain fixed yield rate protocol, don't hesitate to send us your direct and honest feedback [here](https://forms.gle/UqKQ1LqhwAFCBWGBA).

Learn more about the [key upgrades](https://docs.v3.88mph.app/changelog) between 88mph v2 currently available on [Ethereum Mainnet](https://88mph.app/) and v3 on [Ethereum Rinkeby](https://88mph.app/rinkeby/).

## 88mph products

88mph offers two non-custodial on-chain products:

1. A [fixed-term fixed-rate yield product](https://docs.v3.88mph.app/getting-started/fixed-apy) acting as an intermediary between you and third-party variable yield rate lending protocols to offer the best fixed yield rate on your capital, with a custom or preset maturity.
2. A yield speculation instrument, called [Yield Tokens](https://docs.v3.88mph.app/getting-started/yield-tokens) (YTs),  allowing users to speculate on the variable yield rate of third-party protocols such as Compound or Aave.

By using these products, users receive[ MPH tokens](https://docs.v3.88mph.app/mph-token/mph-rewards) that can be [staked](https://docs.v3.88mph.app/mph-token/mph-staking) to earn protocol revenues and exercise voting rights.
