Configuración
Los contratos inteligentes Stellar son pequeños programas escritos en el lenguaje de programación Rust.
Para crear y desarrollar contratos, necesitas los siguientes requisitos previos:
- Una cadena de herramientas de Rust
- Un editor que admita Rust
- Stellar CLI
Instalar Rust
- macOS/Linux
- Windows
- Other
Si usa macOS, Linux u otro sistema operativo tipo Unix, el método más simple para instalar una toolchain de Rust es instalar rustup. Instala rustup con el siguiente comando.
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Luego reinicia la terminal.
En Windows, descarga y ejecuta rustup-init.exe. Puedes continuar con la configuración predeterminada presionando Enter.
El Stellar CLI usa emojis en su salida. Para renderizarlos correctamente en Windows, se recomienda usar el Windows Terminal. Consulta cómo instalar Windows Terminal en Microsoft Learn. Si se usa la CLI en la ventana de comandos de Windows o en PowerShell, funcionará como se espera, pero los emojis aparecerán como signos de interrogación.
Si ya estás usando WSL, también puedes seguir las instrucciones para Linux.

Instalar el objetivo
You'll need a "target" for which your smart contract will be compiled. Qué objetivo necesitas dependerá de la versión de Rust que estés usando.
Para Rust v1.85.0 o superior, instala el objetivo wasm32v1-none.
rustup target add wasm32v1-none
Para versiones anteriores de Rust, instala el objetivo wasm32-unknown-unknown.
rustup target add wasm32-unknown-unknown
Configure an editor
Many editors have support for Rust. Visit the following link to find out how to configure your editor: https://www.rust-lang.org/tools
Here are the tools to you need to configure your editor:
- Visual Studio Code as code editor (or another code editor that supports Rust)
- Rust Analyzer for Rust language support
- CodeLLDB for step-through-debugging
Install the Stellar CLI
The Stellar CLI can execute smart contracts on futurenet, testnet, mainnet, as well as in a local sandbox.
The latest stable release is v22.6.0.
Install
There are a few ways to install the latest release of Stellar CLI.
- macOS/Linux
- Windows
Install with Homebrew (macOS, Linux):
brew install stellar-cli
Install with cargo from source:
cargo install --locked [email protected] --features opt
Using the installer:
- Download the installer from the latest release.
- Go to your Downloads folder, double click the installer and follow the wizard instructions.
- Restart your terminal to use the
stellarcommand.
Using winget:
winget install --id Stellar.StellarCLI --version 22.8.1
Install with cargo from source:
cargo install --locked [email protected] --features opt

Autocompletion
You can use stellar completion to generate shell completion for different shells. You should absolutely try it out. It will feel like a super power!
- Bash
- ZSH
- fish
- PowerShell
- Elvish
Para habilitar el autocompletado en la sesión actual del shell:
source <(stellar completion --shell bash)
To enable autocomplete permanently, run the following command, then restart your terminal:
echo "source <(stellar completion --shell bash)" >> ~/.bashrc
Para habilitar el autocompletado en la sesión actual del shell:
source <(stellar completion --shell zsh)
To enable autocomplete permanently, run the following commands, then restart your terminal:
echo "source <(stellar completion --shell zsh)" >> ~/.zshrc
Para habilitar el autocompletado en la sesión actual del shell:
stellar completion --shell fish | source
To enable autocomplete permanently, run the following command, then restart your terminal:
echo "stellar completion --shell fish | source" >> ~/.config/fish/config.fish
To enable autocomplete on the current shell session:
stellar completion --shell powershell | Out-String | Invoke-Expression
To enable autocomplete permanently, run the following commands, then restart your terminal:
New-Item -ItemType Directory -Path $(Split-Path $PROFILE) -Force
if (-Not (Test-Path $PROFILE)) { New-Item -ItemType File -Path $PROFILE | Out-Null }
Add-Content $PROFILE 'Set-PSReadlineKeyHandler -Key Tab -Function MenuComplete'
Add-Content $PROFILE 'stellar completion --shell powershell | Out-String | Invoke-Expression'
If you get an error like cannot be loaded because running scripts is disabled on this system, you may need to change your Execution Policy with Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope CurrentUser. Before running this command, be sure you understand the implications of doing so.
To enable autocomplete on the current shell session:
source (stellar completion --shell elvish)
To enable autocomplete permanently, run the following commands, then restart your terminal:
echo "source (stellar completion --shell elvish)" >> ~/.elvish/rc.elv
Configuring the CLI for Testnet
Configure an Identity
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. Notice that the account will be funded using Friendbot.
stellar keys generate --global alice --network testnet --fund
You can see the public key of alice with:
stellar keys address alice
Like the Network configs, the --global means that the identity gets stored in ~/.config/stellar/identity/alice.toml. You can omit the --global flag to store the identity in your project's .stellar/identity folder instead.
We previously used ~/.config/soroban (global) and .soroban (local) as the configuration directories. These directories are still supported, but the preferred name is now ~/.config/stellar and .stellar moving forward.
