revm is a high-performance Ethereum Virtual Machine (EVM) written in Rust. Designed with an emphasis on speed and simplicity, revm provides a fast and flexible EVM implementation, featuring a simple interface and an embedded Host. It successfully passes all the ethereum/tests test suites, ensuring compatibility and reliability.

Guiding Principles

revm adheres to several core principles:

  • EVM Compatibility and Stability: Ensuring stability is paramount in the blockchain industry.
  • Speed: Optimization for high performance, with most decisions aimed at enhancing speed.
  • Simplicity: Simplified internals for easier understanding and extension, and an interface that integrates seamlessly into other projects.
  • Interfacing: [no_std] compliance, enabling use as a WebAssembly (wasm) library and integration with JavaScript and C++ bindings if needed.

Project Structure

The revm project is organized into several crates and binaries:

  • Crates:
    • revm: The main EVM library.
    • revm-primitives: Contains primitive data types.
    • revm-interpreter: Houses the execution loop and instructions.
    • revm-precompile: Manages EVM precompiles.
  • Binaries:
    • revme: A CLI binary used for running state test JSONs.

Building from Source

To build revm from source, follow these steps:

  1. Clone the repository:

    git clone
    cd revm
  2. Build the project:

    cargo build --release

Note: clang is required for building revm with c-kzg or secp256k1 feature flags due to dependencies on C libraries. Install it via apt install clang if not already installed.

Running Ethereum Tests

  1. Navigate to the revme directory:

    cd bins/revme/
  2. Download Ethereum tests:

    git clone
  3. Run the tests:

    cargo run --release -- statetest tests/GeneralStateTests/ tests/LegacyTests/Constantinople/GeneralStateTests

Running Benchmarks

Benchmarks for revm can be found in crates/revm/benches. To run the snailtracer benchmark:

cargo bench --package revm --profile release -- snailtracer

To generate a flame graph for visualizing the runtime of various sections:

cargo flamegraph --root --freq 4000 --min-width 0.001 --package revm --bench bench -- snailtracer

Note: Install flamegraph via cargo install flamegraph if not already installed.

Running Examples

To run an example, such as fork_ref_transact:

cargo run -p revm --features ethersdb --example fork_ref_transact

To generate block traces and write them to JSON files:

cargo run -p revm --features std,serde-json,ethersdb --example generate_block_traces

Used By

revm is utilized by several prominent projects, including:

  • Foundry: A toolkit for Ethereum application development.
  • Helios: An efficient Ethereum light client.
  • Reth: A fast implementation of the Ethereum protocol.
  • Arbiter: A framework for stateful Ethereum smart-contract simulation.
  • Zeth: An open-source ZK block prover for Ethereum.
  • VERBS: An Ethereum agent-based modeling and simulation library.
  • Hardhat: A development environment for Ethereum software.
  • Trin: A Portal Network client providing execution archival access.
  • Simular: A Python smart-contract API with an embedded EVM.
