Klever Development Environment Installer

Install the complete Klever smart contract development environment with a single command.

Quick Start

curl -fsSL https://install.klever.org/install.sh | bash

What Gets Installed

Tool	Purpose
Rust	Smart contract programming language (via rustup)
wasm32v1-none	WebAssembly compilation target for Rust
ksc	Smart contract compiler for KleverVM
koperator	Blockchain CLI — deploy, invoke, and query contracts
klever-sc-meta	Project scaffolding, ABI generation, and builds
wasm-opt	WASM optimization (optional)
Klever MCP	AI tool integration for Claude Code and VS Code (requires Node.js)
Klever KVM IDE	VS Code extension for smart contract development (optional, prompts to install)

Supported Platforms

• macOS (Apple Silicon / arm64)
• macOS (Intel / x86_64)
• Linux (x86_64 / amd64)
• Linux (ARM64 / aarch64)

Windows users should use WSL.

Configuration

Variable	Default	Description
KLEVER_SDK_PATH	~/klever-sdk	Custom install directory for SDK binaries

Example with a custom path:

KLEVER_SDK_PATH="$HOME/.local/klever-sdk" curl -fsSL https://install.klever.org/install.sh | bash

How It Works

1. Platform detection — Identifies your OS and architecture
2. Rust — Installs via rustup if not present, adds wasm32v1-none target
3. SDK binaries — Downloads ksc and koperator from the Klever CDN
4. VM library — Downloads the platform-specific VM execution library
5. Cargo tools — Installs klever-sc-meta and wasm-opt via cargo
6. AI tooling — Configures Klever MCP server for Claude Code and VS Code (if Node.js is available)
7. VS Code extension — Prompts to install the Klever KVM IDE extension (if VS Code is available)
8. PATH setup — Adds the SDK directory to your shell profile

The script is idempotent — safe to run multiple times. It skips already-installed components and upgrades outdated ones. No root access is required for the SDK itself; however, on fresh Linux systems, sudo may be used to install build dependencies (C compiler, pkg-config, OpenSSL headers).
