# Developers

By leveraging W3bstream, developers can efficiently process and validate device data before committing proofs of physical work to the blockchain, ensuring integrity of data processing and reducing on-chain computation costs. 

This guide outlines the steps necessary to integrate W3bstream into your DePIN project, from setting up a local development environment to deploying your configuration on the IoTeX blockchain. To use W3bstream as the off-chain compute layer in a DePIN project, developers should follow these steps:

1. **Run a local W3bstream node**: Set up and run a W3bstream node on your local machine to facilitate the development and testing process.
2. **Build the prover logic**: Develop the logic that processes and verifies device data, ensuring it meets the necessary criteria before being sent to the blockchain.
3. **Create a W3bstream configuration file**: Compile a configuration file that includes your prover code, specifying how W3bstream should handle and process incoming data.
4. **Test the W3bstream prover locally**: Validate your prover logic and configuration file by running tests locally to ensure everything functions correctly.
5. **Deploy the W3bstream configuration to the IoTeX blockchain**: Once testing is complete, deploy your configuration to the IoTeX blockchain, enabling your DePIN project to leverage W3bstream's off-chain compute capabilities in a live environment.

## **Prerequisites**

{% hint style="info" %}

1. **ioctl CLI**

Ensure that you have [installed the IoTeX ioctl client](/depin/builders/reference-docs/ioctl-client.md) before proceeding:

```
curl https://raw.githubusercontent.com/iotexproject/iotex-core/master/install-cli.sh | sh
```

{% endhint %}

2\. **Testnet endpoint**

ioID is currently on testnet. Ensure you have configured ioctl with the IoTeX testnet endpoint:

`ioctl config set endpoint api.testnet.iotex.one:443`

[->See more IoTeX RPC Endpoints](broken://pages/wE7ygzp4L2PEHkewex1X)
{% endhint %}

3\. **Test Tokens**

Ensure you have some IOTX test tokens in your wallet balance
