Introduction

ZombieNet SDK is a Rust testing framework for Polkadot SDK-based blockchains. It spawns ephemeral blockchain networks programmatically for testing and development.

The SDK succeeds the original ZombieNet (TypeScript), offering a type-safe, composable Rust API.

Migrating from TypeScript ZombieNet? The TOML configuration format is largely compatible. See Network Definition Spec for the full reference.

Key Features

• Programmatic Network Spawning - Define and spawn relay chains and parachains from Rust code
• Fluent Builder API - Compose networks using a chainable builder pattern
• Multiple Providers - Run on Kubernetes, Podman, Docker, or natively
• Metrics & Assertions - Query Prometheus metrics and validate network behavior
• Subxt Integration - Interact with networks using subxt

Use Cases

• Integration Testing - Test cross-chain functionality with complete networks
• CI/CD Pipelines - Automate network deployment and testing
• Development - Spin up local networks for development and debugging
• Parachain Testing - Test registration, block production etc.
