# Get Started

## Requirements

If you want to create an x2earn app it needs to have the following features:

* Be able to **distribute B3TR** tokens on the VeChain blockchain
* Be able to **submit a proof** (in JSON format) of the sustainable action the user was rewarded for

Bonus:

* Allow the user to **connect** with their [wallet](https://vechain-kit.vechain.org/) to your app

This guide provides instructions for setting up a project within the VeBetter ecosystem. Your app will participate in weekly allocation rounds, receive B3TR tokens at the beginning of each round, and distribute these

## Test Environment

Use our [Test Environment](https://staging.testnet.governance.vebetterdao.org/) to create a test app running **in the VeBetter ecosystem.**

## **Distribute B3TR**

Get some B3TR tokens on testnet, add a reward distributor then connect a smart contract or a backend and distribute rewards to your users.

## Proofs and Impacts

Every time you reward a user you also need to specify the reason, the proof of the user's action and the sustainability impact it had.

## Security

{% hint style="danger" %}
Before going live be sure to go through our [Security Considerations](/developer-guides/security-considerations.md) along the [RuleBook](/developer-guides/rulebook-for-apps.md). Make sure to apply security measures to your app, avoiding hacks and farmers.
