# Protocol Integrations (V5)

## Getting Started

For an on-chain integration to a dynamic vault contract, you can start by viewing the contract source code on Etherscan or Snowtrace, which will provide you the contract source code, a list of functions and their descriptions, as well as all of the libraries, interfaces, factories, and controllers. 

{% hint style="info" %}
Dynamic vaults implement the [OpenZeppelin ERC-1967 Upgradeable Beacon Proxy ](https://docs.openzeppelin.com/contracts/4.x/api/proxy#UpgradeableBeacon)Pattern. 
{% endhint %}

## Contract Documentation

{% hint style="info" %}
Each vault is a unique smart-contract with a unique address. You can find a list of vault contracts and their blockexplorer pages [here](/opentrade-sandbox/contract-addresses.md). There you can View the Proxy Contract Source Code and [View the Implementation Contract Source Code](https://etherscan.io/address/0x11fff7f8ffa78c537cab26be142d2ee91ea9622c#code), including the source code, interfaces, factories, controllers, and libraries. 
{% endhint %}

#### Using Etherscan to View Documentation

## Important Functions&#x20;

As a Lender, there are only a handful of functions you will ever need to call.  These three are covered in more detail below. There are quite a number more in detailed in the full code, libraries, and interfaces on Etherscan and Snowtrace but we present the most important below.&#x20;
