<title>Install and configure Rust to deploy smart contracts.</title>Soroban contracts are small programs written in the Rust programming language.
To build and develop contracts you need only a couple prerequisites:
- A Rust toolchain
- An editor that supports Rust
- Soroban CLI
If you use macOS, Linux, or another Unix-like OS, the simplest method to install a Rust toolchain is to install rustup
. Install rustup
with the following command.
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
If you use Windows, or need an alternative method of installing Rust, check out: https://www.rust-lang.org/tools/install
Install the wasm32-unknown-unknown
target.
rustup target add wasm32-unknown-unknown
Many editors have support for Rust. Visit the following link to find out how to configure your editor: https://www.rust-lang.org/tools
A popular editor is Visual Studio Code:
- Visual Studio Code editor.
- Rust Analyzer for Rust language support.
- CodeLLDB for step-through-debugging.
The Soroban CLI can execute Soroban contracts in the same environment the contract will execute on network, however in a local sandbox.
Install the latest released version of Soroban CLI using cargo install
.
cargo install --locked soroban-cli

Run the soroban
command and you should see output like below.
soroban
$ soroban
Build, deploy, & interact with contracts; set identities to sign with; configure networks; generate keys; and more.
Intro: https://soroban.stellar.org
CLI Reference: https://github.com/stellar/soroban-tools/tree/main/docs/soroban-cli-full-docs.md
Usage: soroban [OPTIONS] <COMMAND>
Commands:
completion Print shell completion code for the specified shell
config Deprecated, use `soroban keys` and `soroban network` instead
contract Tools for smart contract developers
events Watch the network for contract events
keys Create and manage identities including keys and addresses
lab Experiment with early features and expert tools
network Start and configure networks
version Print version information
Options:
--global Use global config
-f, --filter-logs <FILTER_LOGS> Filter logs output. To turn on "soroban_cli::log::footprint=debug" or off "=off". Can also use env var `RUST_LOG`
-q, --quiet Do not write logs to stderr including `INFO`
-v, --verbose Log DEBUG events
--very-verbose Log DEBUG and TRACE events [aliases: vv]
--list List installed plugins. E.g. `soroban-hello`
-h, --help Print help (see more with '--help')
-V, --version Print version
TESTING_OPTIONS:
--config-dir <CONFIG_DIR> Location of config directory, default is "."
:::info
Protip: You can use soroban completion
to generate shell completion for bash
, elvish
, fish
, powershell
, and zsh
. You should absolutely try it out. It will feel like a super power!!
To enable autocomplete in the current bash shell, run:
source <(soroban completion --shell bash)
To enable autocomplete permanently in future bash shells, run:
echo "source <(soroban completion --shell bash)" >> ~/.bashrc
Users of non-bash shells may need to adapt the above commands to suit their needs.
:::
Soroban has a test network called Testnet that you can use to deploy and test your smart contracts. It's a live network, but it's not the same as the Stellar public network. It's a separate network that is used for development and testing, so you can't use it for production apps. But it's a great place to test your contracts before you deploy them to the public network.
To configure your CLI to interact with Testnet, run the following command:
soroban network add --global testnet \
--rpc-url https://soroban-testnet.stellar.org:443 \
--network-passphrase "Test SDF Network ; September 2015"
Note the --global
flag. This creates a file in your home folder's ~/.config/soroban/network/testnet.toml
with the settings you specified. This means that you can use the --network testnet
flag in any Soroban CLI command to use this network from any directory or filepath on your system.
If you want project-specific network configurations, you can omit the --global
flag, and the networks will be added to your working directory's .soroban/network
folder instead.
When you deploy a smart contract to a network, you need to specify an identity that will be used to sign the transactions.
Let's configure an identity called alice
. You can use any name you want, but it might be nice to have some named identities that you can use for testing, such as alice
, bob
, and carol
.
soroban keys generate --global alice --network testnet
You can see the public key of alice
with:
soroban keys address alice
Like the Network configs, the --global
means that the identity gets stored in ~/.config/soroban/identity/alice.toml
. You can omit the --global
flag to store the identity in your project's .soroban/identity
folder instead.
By default, soroban keys generate
will fund your account using Friendbot. If you don't want this behavior, run this command with --no-fund
.
