Setting Up Your Environment

Environment configuration instructions to get started developing on Secret Network.

Secret Contracts are written using the CosmWasm framework. CosmWasm contracts are written in Rust, which is later compiled to WebAssembly (or WASM for short). To write our first Secret Contract, we need to set up a LocalSecret development environment with all the tools required so that you can upload, instantiate, and execute your smart contracts.

For a step-by-step Secret Network environment configuration video tutorial, follow along here πŸŽ₯. Otherwise, continue reading!

What Is LocalSecret?

LocalSecret is a complete Secret Network testnet and ecosystem containerized with Docker. It simplifies the way secret contract developers test their contracts in a sandbox before they deploy them on a public testnet or mainnet (You can think of it like a local testnet that only you have access to).

There are 3 main tools we will use -

  • IDE - a development environment (usually VS Code or JetBrains CLion/IDEA with Rust support)

  • SecretCLI - a command-line tool to interact with the blockchain

  • LocalSecret - a local Secret Network chain set up for development purposes

We're going to install our environment manually so that you can code in a text editor of your choosing, but if you would prefer to work with JetBrains you can also configure your environment that way using the resources at the bottom of this page.

Install Requirements

To follow along with the guide, we will be using git, make, rust, and docker.

sudo apt-get install git make

Install Rust

curl --proto '=https' --tlsv1.2 -sSf | sh

Add WASM build target

rustup target add wasm32-unknown-unknown

Having Trouble? You might need to restart your terminal, or run a command like:

source "$HOME/.cargo/env"

After installing Rust to configure the current shell

Install Cargo Generate

Cargo generate is the tool you'll use to create a smart contract project. Learn more about cargo-generate here.

cargo install cargo-generate --features vendored-openssl

Install Docker

Docker is an open platform for developing, shipping, and running applications.

Install SecretCLI

SecretCLI is a command-line tool that lets us interact with the Secret Network blockchain. It is used to send and query data as well as manage user keys and wallets.

chmod +x secretcli-Linux
sudo mv secretcli-Linux /usr/local/bin/secretcli

For a more detailed and in-depth guide on SecretCLI installation and usage, check out the documentation here.

Install LocalSecret

An instance of LocalSecret requires approximately 2.5 GB of RAM to run. You may need to increase the resources available in your Docker settings.

The installation methods differ based on the processor architecture. This is because Secret Network makes use of Intel SGX to protect private data.

Now that you have docker installed, open the docker application and then in your terminal run:

docker run -it -p 9091:9091 -p 26657:26657 -p 1317:1317 -p 5000:5000 \
  --name localsecret

Congrats! You now have a containerized version of LocalSecret running inside docker! You should see blocks being created in real time:

Now it's time to learn how to compile and deploy your first smart contract πŸŽ‰

Additional Resources

JetBrains Dev Environment (Secret IDE)

The amazing folks at Digiline created a prebuilt containerized environment containing an IDE (IntelliJ IDEA) that contains everything you need to get started. If you're comfortable with JetBrains IDEs, this may be a good choice for you.

To complement Secret IDE, we will set up another docker container with LocalSecret, where we will deploy our contracts to test and play around with.

To get started, visit, or just go for it and run the IDE from docker:

docker run -p 8888:8888 -it

Then after a few seconds you will be able to access your in-browser IDE at https://localhost:8888.

Once the environment loads, clone the repository from

Secret IDE has built-in support for both the Pulsar testnet and mainnet, but for the purposes of this guide we will be using the SecretCLI via terminal.

Secret-IDE is also available as a plugin for IDEA, so you can just install it from the marketplace.

Lastly, it will be helpful to configure SecretCLI by using the included "Configure secretcli" command which will set up SecretCLI to target the public testnet

Gitpod Set Up Instructions (for M1 Mac users)

LocalSecret cannot be run on an M1 Mac.

To know whether you have a Mac with an M1 chip or an Intel chip, click on the Apple logo located in the lefthand corner of your desktop and navigate to About This Mac/Overview, and confirm whether the processor is M1 or Intel. If you have an Intel chip, you can run LocalSecret in docker, otherwise, proceed with these set up instructions to learn how to run LocalSecret in Gitpod.

  1. Run an instance of LocalSecret in Gitpod by clicking here.

  2. Gitpod will automatically create a workspace and ask if you want to open it in your text editor. It will then prompt you to allow an extension to open the URI. Select "Open" to proceed.

  3. If you don't have a registered SSH public key for your computer in your Gitpod account, it will ask you to copy a temporary password to use until you restart the workspace at a later date. Copy the password.

  4. Enter the password you copied in your text editor to finish setting up the SSH host connection.

  5. Congrats! You have successfully set up an instance of LocalSecret in Gitpod which you can use for testing your smart contracts.
