Getting Started

Developing interoperability technology—or working across multiple chains simultaneously—requires a complex local development setup. You'll often need to run various chains and off-chain services concurrently. Consider a simple application that aggregates traffic from Ethereum, Solana, and Hyperliquid. Such an application would need to operate:

Development Environments:

• Ethereum devnet
• Arbitrum devnet (required for Hyperliquid settlement)
• Solana devnet
• Hyperliquid devnet

Services:

• Relayer
• Indexer
• Database
• Frontend

Programming Languages and Tools:

• Solidity (via solc)
• Rust
• Golang
• Typescript
• Docker

This list continues to grow as projects become more sophisticated. Managing tool versions across different developers becomes a significant challenge. Currently, there are two main approaches for handling complex setups like this: Bazel and Nix. Throughout this book, we'll use Nix—our Goblin-approved solution—to manage these development environments efficiently.
