# Public Testnet

The launch of fully-integrated testnet is a public good initiative by Gelato and 10+ partners to lower the barriers for developers and help them build and test the next generation of applications in a production-ready environment. Our public testnet is entirely free to use, opening up a world of possibilities for developers, students, and innovators worldwide.

## What is Gelato's Fully-Integrated Public Testnet?

Developers can start building using this public testnet:

## Obtaining Testnet Tokens

Arbitrum Blueberry utilizes a custom gas token, which requires a different acquisition process. Here's how you can get started:

### 1. Minting CGT on Arb Sepolia

Begin by visiting the designated faucet for Arb Sepolia to mint your CGT. This initial step is crucial for obtaining the gas token needed for transactions on Arbitrum Blueberry. Access the faucet [here](https://app.gelato.cloud/rollups/details/public/arb-blueberry).

### 2. Bridging CGT to Arbitrum Blueberry

After minting CGT on Arb Sepolia, the next step involves bridging these tokens to Arbitrum Blueberry. This process is facilitated through [Arbitrum Blueberry](https://bridge.gelato.network/bridge/arb-blueberry) bridge service designed to seamlessly transfer your CGT, enabling you to use it for transaction fees within the Arbitrum Blueberry environment.
