# DeFi Smart Account (DSA)

Smart Account for Decentralized Finance

## What is a DeFi Smart Account?

The DeFi Smart Account or DSA for short; is a smart contract wallet and smart contract infrastructure that allows for extensible products and composability across a variety of DeFi protocols. The DSA SDK is open source and can be built upon by developers and users alike.

Our flagship interface is located at [defi.instadapp.io](https://defi.instadapp.io/)

## Instadapp GUI and DSA

Instadapp maintains its flagship GUI. DeFi Smart Accounts (DSA) are non-custodial smart contract wallets and therefore any developer can choose to build additional interfaces or add functionality into the DSA or use the SDK to build a separate independent application.

The Instadapp GUI is a streamlined DApp which is meant to offer lots of functionality in a consistent manner. You can also manually execute transactions using the SDK by creating your own transactions.

The SDK is accessible on the interface through the use of console in case you need to execute a function not accessible through the GUI.
