Klave Rust Templates Collection

A collection of Rust templates for building Klave applications using cargo-generate. Each template provides a specialized foundation for different use cases within Trusted Execution Environments (TEEs).

📖 About

Klave aims to make it easy to build and deploy WebAssembly applications within Trusted Execution Environments (TEEs) and leverage the latest developments in the WebAssembly component model and Wasmtime runtime.

For detailed documentation, please read the Klave docs.

📦 Prerequisites

To use these templates, ensure the following tools are installed:

• The Rust Toolchain (incl. rust, rustup, cargo)
• cargo-generate: cargo install cargo-generate
• cargo-component: cargo install cargo-component
• wasm32-unknown-unknown target: rustup target add wasm32-unknown-unknown

🧩 About Klave Applications

All Klave apps are WebAssembly components that:

• Run within Trusted Execution Environments (TEEs)
• Provide cryptographic guarantees of integrity and confidentiality
• Support both queries (read operations) and transactions (write operations)
• Use the WebAssembly Interface Types (WIT) for component interfaces
