About RethLab
Hyperliquid, Tempo, Base — the new wave of EVM chains is Rust-native. RethLab is the training program that brings you up to speed by walking the real Reth, Revm, Alloy, and Foundry source line by line.

Reth, Revm, and Alloy are at the heart of the most performant chains being built today. But the on-ramp from "I know some Rust" to "I can write production EVM infrastructure" is brutal — the docs are scattered, the source is dense, and there is no clear path. RethLab is that path: 4 tiers, ~74 lessons, every advanced concept grounded in actual production source. Finish it and you can read Reth's stages, write custom Revm precompiles, ship an ExEx, and apply for grant work with code samples that prove you understand the stack.
Memory safety, zero-cost abstractions, and an ecosystem mature enough to power serious blockchain infrastructure.
A modular, blazing-fast Ethereum client from Paradigm — the foundation many App-chains build on.
The Rust EVM that powers Reth, Foundry, and most modern simulation tooling.
The next-generation type-safe library for Ethereum in Rust — the modern replacement for ethers-rs.
Why This Stack?
Reth, Revm, and Alloy are quietly becoming the standard for serious Ethereum infrastructure.
Reth: Modular Rust Ethereum client — faster sync, lower memory, and the basis of many App-chains.
Revm: World-class Rust EVM — used inside Reth, Foundry, OP-Reth, and most zkVMs.
Alloy: Type-safe Ethereum primitives — the modern replacement for ethers-rs.
ExEx: Reth Execution Extensions — hook directly into the execution loop in Rust.
Compose: Use Alloy to talk to any chain, drive Revm in process, or extend Reth as a node operator.
Career value: Infra engineers who can read this stack are some of the highest-paid in Web3.
Why this exists
Most EVM tutorials describe what's happening. The kind of engineers Paradigm, Hyperliquid, and Monad hire have actually read the source. RethLab closes that gap by walking you through real Reth, Revm, Alloy, and Foundry source code — line by line, with the design intent — so by the time you open a crate, you've already seen its key code.
What's Next
More Content
Deeper Revm internals (precompiles, EOF), Reth SDK walkthroughs, and ExEx case studies.
Multi-Language
Available in English and Japanese, with parity across both. More languages planned as the community grows.
More Courses
As the Rust Ethereum ecosystem evolves — new opcodes, new ExEx patterns, new chains — new lessons will follow.
Support this work
RethLab is free and open. If the lessons helped you ship Rust EVM code, sponsoring on GitHub or a one-time donation keeps the course running and the existing material updated against upstream.
