Setting up the GenLayer Simulator is like getting ready to play with your very own high-tech vending machine. The Simulator lets you build and test Intelligent Contracts in a safe space before launching them on the real blockchain. Don’t worry, it’s easier than you think!
Curious to learn more about Intelligent Contracts? Then read this blog post!
Step 1: Install the GenLayer SDK
First, you need the tools to start building. To do that, you’ll install the GenLayer SDK (Software Development Kit). This is like the foundation you need to create your Intelligent Contracts. The SDK helps you connect to the Simulator, write your contracts, and see how they would work on the testnet.
Here’s how to install it:
- Download the SDK: Head to the official GenLayer documentation and download the SDK onto your computer.
- Follow the installation steps: The SDK comes with everything you need, so just follow the instructions, and you’ll be ready to go.
Step 2: Connect to the Simulator
Once the SDK is installed, you’re ready to connect to the GenLayer Simulator. This is the part where you get to test out your ideas in a safe environment without worrying about making mistakes.
- Open the SDK: Launch the SDK on your computer.
- Run the Simulator: From the SDK, connect to the GenLayer Simulator. It’s like opening a practice space where you can see how your contracts will behave.
- Start coding: Now you’re all set to write your first Intelligent Contract! The best part? You can use Python, so if you’ve ever written even basic code, you’ll feel right at home.
Step 3: Build and Test
Now the fun part begins—start building! In the Simulator, you can create your Intelligent Contracts, test them out, and fix any issues along the way.
- Experiment freely: Since you’re working in a safe environment, there’s no risk of messing up real transactions.
- Seamless transition: Whatever you create in the Simulator can be transitioned to GenLayer’s testnet later, so your work won’t be wasted!
Step 4: Join the Community
GenLayer has an active community of developers, so if you ever get stuck or need help, there are plenty of resources and people to guide you. Whether it’s through forums or Discord channels, you’re never alone when setting up the Simulator.

Code with the GenLayer Studio
GenLayer has launched Studio, an upgraded, browser-based application for developing Intelligent Contracts. Using a Python-based SDK and the GenVM execution environment, Studio enables developers to prototype contracts with AI-powered functionality and native internet access. Ideal for use cases like prediction markets and parametric insurance, Studio supports testing and debugging, preparing developers for GenLayer’s testnet and mainnet.

How Can I Set Up the GenLayer Simulator?
The GenLayer Simulator allows developers to build and test Intelligent Contracts in a safe environment before launching on the real blockchain. By installing the GenLayer SDK, connecting to the Simulator, and using familiar coding languages like Python, developers can experiment freely, refine their contracts, and seamlessly transition them to the testnet.

Why does GenLayer have a simulator and how to use it?
GenLayer’s Simulator provides a safe environment for developers to test and build decentralized applications (dApps) using Intelligent Contracts. It allows experimentation without risking real blockchain errors. Developers can code in Python or WASM, transition projects smoothly to the testnet, and perfect dApps before official deployment, improving reliability and user experience.
