# Introduction

BUIDLer is a react component that allows plug-and-play integration with the Etherspot SDK, allowing dApps and developers to easily leverage the SDK in a highly customisable fashion.

## In a nutshell

The Etherspot BUIDLER React component allows anyone to implement transfers, contract interactions, swaps, crosschain bridging and more into their own dApp with just a few lines of code.

The BUIDLER component takes care of the technical requirements behind the scenes to provide a great user experience to your users.

## Everything is a "block"

One of the most important concepts to understand is that every **action** that a user can perform is represented as a **block**. Each block can be performed as a batch transaction (where several actions are executed as one transaction) or in a sequence (where each transaction happens one after another).

We've included several blocks that help facilitate actions out the box, and we've created a guide on how to create your own block.
