# Smart Contracts and Documentation

Summer.fi's code is **fully open-source,** giving everyone in the community the ability to pressure test and audit the core technology. We built on top of heavily audited and long standing lending protocols. 

This page provides all relevant links and documentation as a reference. If you think you have found a bug or security issue you can report it on immunefi: <https://immunefi.com/bounty/summerfi/> and your report will be treated with the highest priority.

### High level Summer.fi Architecture

The architecture of Summer.fi consists of 5 layers:

1. Summer.fi webapp - <https://summer.fi/>
   * This is where the magic happens. Here you view & interact with your DeFi positions.
   * Code for the UI: <https://github.com/OasisDEX/oasis-borrow>
2. DeFi Smart Account Layer
   * To enable better UX, users first need to create a DeFi Smart Account. This is a proxy layer that manages positions on the blockchain.
   * Code for the contracts: <https://github.com/OasisDEX/oasis-earn-sc>
3. Summer.fi Automation contracts & Automation workers
   * If you wan to automate your position with a stop loss or other trigger, then those will be recorded in the automation trigger contracts, which get executed only when eligible by the Automation workers. &#x20;
   * Code for automation  <https://github.com/OasisDEX/automation-mono> , <https://github.com/OasisDEX/automation-workers>
4. Summer.fi Contract layer
   * The smart contracts that enable the Borrow, Multiply and Earn functionality.
   * Code for the contracts <https://github.com/OasisDEX/multiply-proxy-actions>, <https://github.com/OasisDEX/oasis-earn-sc>
5. The Defi protocols themselves, that Summer.fi users interact with through the above layers.

High level, this is how these layers fit together.
