# Introduction to GEB [GEB](https://en.wikipedia.org/wiki/G%C3%B6del,_Escher,_Bach) is a framework for deploying systems that can issue [stablecoins](https://medium.com/reflexer-labs/stability-without-pegs-8c6a1cbc7fbd). Stablecoins don't look like [this](https://www.coingecko.com/en/coins/usd-coin) (that's a pegged coin), but rather like [this](https://duneanalytics.com/HggqX/Reflexer-RAI). Stablecoins are a great collateral source for other DeFi protocols (compared to ETH or BTC) and are also a store of value with an embedded funding rate.\ \ This documentation is meant to explain all the components behind GEB. Before diving in the docs, we recommend reading our original [whitepaper](https://github.com/reflexer-labs/whitepapers/blob/master/English/rai-english.pdf).\ \ GEB is a modified fork of [MCD](https://github.com/makerdao/dss) that has several core differences: * Variable names you [can actually understand](https://docs.reflexer.finance/contract-translation/naming-transition) * An autonomous feedback mechanism that changes the incentives of system participants * The possibility to add insurance for SAFEs * Fixed and increasing discount auctions (instead of English auctions) used to sell off collateral * Automatic adjustment of several parameters in the system * A set of contracts that bound control over parameters that are governed in the long run * The possibility to send stability fees at once to multiple addresses * The possibility to switch between surplus auctions and other types of strategies meant to remove surplus from the system * Two prices for each `CollateralType`: one used for generating debt, the other one used exclusively when liquidating SAFEs * A stability fee treasury that can pay for oracle calls or other contracts that automate the system ### GEB Overview Diagram Explore the diagram in detail [here](https://viewer.diagrams.net/?target=blank\&highlight=0000ff\&layers=1\&nav=1\&title=GEB_overview.drawio#Uhttps%3A%2F%2Fdrive.google.com%2Fuc%3Fid%3D1nIcaY8N8StVCfyAL_ztbmETJX2bvY3a9%26export%3Ddownload). ![](https://4210779308-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-M9jdHretGKCtWYz5jZR%2F-MZCEBuqpWiVDbzkVeUa%2F-MZCEJv2Xvz-xIw0JAwy%2FGEB_overview%20\(1\).png?alt=media\&token=d1233706-ec95-443b-8d45-97f973d18208) {% file src="" %}
